Tonight on The Curse of Oak Island.

The plan is to go in the water to find the anomalous stone.

I swam that northerly bearing and I came across another big triangle rock.

Christopher Columbus was responsible for the ark coming to Oak Island.

You good?

Okay, let's go. We're two dives away from getting answers to a 40-year quest.

He's under. Finish 10x. What's in the bottle? Michael, do you copy?

Can you hear me?

there is an island in the north atlantic where people have been looking for an

incredible treasure for more than two hundred years so far they have found

bits of gold chain a stone slab with strange symbols carved into it even a

seventeenth-century spanish coin to date six men have died trying to solve the

mystery and according to legend One more will have to die

before the treasure can be found.

It is the start of another challenging week on Oak Island, and brothers Rick

and Marty Lagina remain determined to reach this year's biggest goal.

to get a human being to the bottom of borehole 10X.

Okay, time to talk to Harvey.

After weeks of searching and several setbacks, they believe they have finally

found someone who is both qualified and courageous enough to attempt the

perilous 235-foot dive.

Now, have we decided he's going to do it? Well, I think he has to decide that.

So, Harvey, good morning. Good morning. Good morning. Gentlemen.

Wait, who are you talking to?

Yeah, use that term very loosely.

Harvey Morash is a certified deep-wreck diver from Cape Breton, Nova Scotia, who

has nearly 25 years of experience exploring dangerous and confined

environments from shipwrecks to underwater cave systems.

Where are you at emotionally on the thing?

It's definitely very interesting. Okay. I mean, who doesn't want to explore?

Yeah. Who doesn't want to go on a treasure hunt?

Well, to me, it's not even about treasure. It's just the exploration.

Right. It's not so much the dive. It's the deal with problems.

Right. You know, for technical diving, that's the key, being able to deal with

a problem and keeping a cool head.

Right. Yeah. Because the second you panic, it's game over. You're going to

make a bad situation much worse.

I think Harvey's a good candidate.

He's a cave diver. This is very akin to a cave with a shaft going to it.

You know, so cave divers are used to being in enclosed spaces. They're used

to visibility being an issue.

Coming up easy.

Although the team has spent the last several weeks clearing debris and

obstructions from 10X all the way down to the 181-foot level, Marty and

Rick remain concerned.

that an old drill bar that fell down 10x some 30 years ago is still wedged

somewhere in the 27 inch portion of the shaft it could present an insurmountable

obstacle especially if harvey is uncertain at exactly what depth the

drill bar is located the exploration part would be to see or feel the top end

of the bar yeah yeah the other thing you'd want to do when you get on bottom

is give that pipe a good tug and push down on and everything before you go in

it because i wouldn't want to be underneath it if it let go that would

make for a very bad dive real bad it's either going to be doable or not yeah

if i can even get in that restriction you can get in we know that's been done

before but harvey uses tanks

If squeezing himself through the 27-inch wide portion of 10X weren't difficult

enough, Harvey will be attempting it while wearing two air tanks on his back.

I can't say how tight it is, but I'm assuming a 27-inch hole, you don't have

a whole lot of room to deal with something, right?

Yep. From a logistical standpoint, I believe it makes much more sense to do a

test run of similar size in 20 feet of water to make sure I can actually fit.

as opposed to 181 feet. Well, we can lay it down flat, then you can just swim

right through it. Yeah. That makes sense, and we want to do this as safely

as possible.

Yes, I agree.

If we set up the practice dive, and it seems feasible after that, then you are

very interested in doing this. Is that a fair statement?

That is a fair statement.

So, Harvey, we will rig up a pipe.

Call you back with the details. We'll see you in a few days. Okay, looking

forward to it.

Good enough.

Thanks, Harvey. Thanks a lot. Take care.

There's no point in this proceeding if he can't get into the 27-inch shaft.

Can he do it or can't he?

Morning.

Here, Skipper, can you stow this?

As Rick, Marty, and their partners wait for Harvey Morash to arrive, they once

again turn their attention to the waters surrounding Oak Island.

Okay, good morning, folks. Welcome back to Blue Phoenix.

What we're going to do is we're going to head out and we're going to look at the

Triangle Stone Anomaly that we came across the other day.

Let's get the show on the road. All right.

Last week...

while the team collected side-scan sonar data some 300 feet off the southern

shore. That's interesting. Look at the triangle.

See the triangle?

Oh, wow.

Professional diver and sonar expert Mike Roberts located what appears to be a

mysterious triangle-shaped object lying at a depth of approximately 20 feet on

the ocean floor.

I don't think Mother Nature made that.

Wow.

Now, Marty Lagina.

his business partner, Craig Tester, and their sons, Alex Lagina and Jack Begley,

have joined divers Tony Sampson, Mike Roberts, Dave Delaney, and marine

archaeologist Rob Peterson in an effort to find out if the strange three-sided

object is, in fact, man-made.

What a beautiful day, eh?

Mike, if we can't find it on a day like today, then we're not going to find it.

So if we don't find it now, it's going to be forever covered in silt and the

next treasure hunters may find it in a thousand years.

Okay, we're going to come around the starboard, guys.

Beautiful, Jack.

I've got it all the way, buddy.

You ready?

You're good?

Yeah.

It's a smart spot, my friend.

Okay, the arse end of Blue Phoenix here is sitting right on the X marks the

spot. So the deal is, Rod, you're running the XO mast today.

Mike's going to be your dive supervisor there. We've got live comms.

So hopefully, in a perfect world, you're going to jump over there and you're

going to see this beautiful triangle rock glowing out of the seabed.

Get the gear on, get in. Let's go see what's there, eh?

Let's go have a look.

The plan is for Rod, the marine archaeologist, to go in the water first,

find the anomalous stone, and then we'll go in and look at it afterwards.

Diver's ready for the water. Diver's clear to go?

Yeah.

Diver in the water!

Approximately 300 feet off the south shore of Oak Island, Marty Lagina, his

son Alex.

Craig Tester and other members of the Oak Island team are searching for a

mysterious triangle-shaped object that might be an important clue in solving

the Oak Island mystery.

Hello, Rod.

Hi there.

All right, dive for leaving surface.

Dive for leaving surface.

Copy. As marine archaeologist Rod Peterson begins a careful exploration of

the ocean floor, his communication system.

will allow him to keep the team informed of his progress.

Diver on bottom.

Diver on bottom.

Rug, what's the visibility like?

Not bad.

I'd say about six to eight meters.

Roger that.

It's mostly sandy with small stones.

No sign of the object yet.

Roger that.

Systems are all working good, right?

So now where's the object?

Rod's on the job.

So far, Rod has been unable to locate the strange triangle-shaped object.

Is it possible that it's been covered by silt and underwater vegetation?

Or, as with so many other anomalies associated with Oak Island, has it too

mysteriously disappeared?

I've seen anything of interest yet, Rod.

Nothing yet.

Roger that, Rod.

There's a lot of seaweed on the bottom.

Suddenly, Rod sees a strange stone formation just a few yards away.

Mike, on the sonar image, were there a lot of smaller rocks around the

triangular rock? Yeah, there were actually little rocks around it.

Okay.

I may have found the target.

Roger that. What have you found, Rod?

There's a large rock down here.

Triangular in shape.

It's covered in seaweed.

Roger that. Well, we found it.

We found the rock.

Now we decide if it means anything.

See if you can see any markings on top of the rock.

Roger.

If this rock really does have markings or evidence that it is man-made, it may

also offer the team clues as to what the treasure is.

who buried it, and more importantly, where it might be found.

Now that Rod has found the triangle-shaped rock, he will make

a thorough inspection of it.

Roger that.

Okay, Rod, we need you to mark that location.

Okay. Rod then deploys an SMB, or submersible marker buoy, to temporarily

mark the location of the stone.

Roger that. Okay, deploying the SMB.

SMB is going to be deployed.

There it is. New beauty.

While Marty Lagina and members of the team wait for Rod Peterson to return to

the boat for a full debriefing, his brother Rick and fellow treasure hunter

Dave Blankenship begin making the final preparations at 10X for Harvey Morash's

potential dive.

They are also trying to determine the exact location of a 20-foot-long drill

bar that is wedged in the 27-inch portion of the shaft.

Look, if we're going to send divers down into the cavity, they need all the

information we can give them. This probe will tell us when it comes in contact

with metal.

To aid them in their efforts, Rick has obtained the Dipper T well casing

indicator, a probe that can detect and record the depth of underground metallic

objects.

As the probe is lowered down 181 feet and into the 27-inch portion of

10X, the magnetic tip will be able to locate any objects that have a magnetic

field, in this case, a steel drill bar.

Okay, so I'll drop it in the 27-inch. You eyeball the measurement.

As soon as it comes in contact with the top of the bar, we'll know where it is

if we can get right on top of it.

What's 181 in meters?

Roughly, I believe it's 55.

55 okay eyeball that what do we got right now yeah 59 58 right there on top

we're in the 27 inch okay at this point it should ring as soon as it comes in

contact with the steel 62 63 on top got 64 coming

up what was that beep that be the bar

that's a good question Hang on to that. Let me get in there and kind of wave it

around.

I don't like that.

Remember when your father came up on that 90 when she collapsed? Yeah.

And what was the first thing he said? Don't tell your mother. Don't tell my

brother.

You think it's on this side of the 27?

Yep.

It is.

Can't be anything but. Okay, there you go. Okay, I'll just... I got 62, 30,

30... 30? 62, 30.

That's where she is.

The probe has located the drill bar at approximately 62 meters, or 204

feet, meaning that it's 23 feet below the mouth of the 27-inch portion of the

borehole.

We now know after all this time, it's at 204 feet.

We've never known that.

Given the difficulty of reaching the bottom of 10X through a narrow 27-inch

wide hole, knowing the exact location of the drill bar might help Harvey maneuver

around it more successfully.

It could also make the critical difference between the dive's success or

failure.

And if Marty and Rick are ever going to find out if there really is a man-made

treasure vault lying some 235 feet below the island's surface.

Okay, let's go.

Now that marine archaeologist Rod Peterson has located what he believes to

be the mysterious triangle-shaped rock, some 300 feet off of the southern shore

of Oak Island.

Marty Lagina and the team are eager to hear his professional analysis.

debriefing time tell us what did you see what does it mean you know are you

excited about it is it man-made are there chisel marks is it golden idols

you know anchor points what i definitely think it's the object we saw on the

sonar survey it's a larger rock and a field of smaller ones definitely

triangular in shape with indentation on the top that's probably the shadow we

picked up

I took bearings off all points on the triangle, and one of the points on the

indentation was directly 0 to 180, that bearing that we were looking for heading

back towards the island.

Fantastic.

Zero degrees points exactly back to that orange marker on the land, which is the

stone triangle.

Before the dive, Tony Sampson marked the place on the island's south shore, where

a mysterious triangle of stones was first discovered back in 1897.

Although various excavations and treasure searches caused the stones to

be lost over the years, it is believed that they pointed directly at the money

pit.

All right, I think we got something to look at, Alex. Yeah.

I mean, not that we know what we're doing. Yes, let's get in the water, you

know, let's give it a try. What the hell?

The marine archaeologists thought that it could have some man-made features to

it. Hey, that's exciting.

I want to see it.

Okay, you ready?

Yep. Okay.

Okay, guys, the plan?

Go down, check out the rock.

We'll use the line as a reference.

Okay, so follow her down.

If the stone triangle in the water can be identified as pointing in the

direction of the old stone triangle, and the money pit it could be evidence that

it was deliberately left there as a marker perhaps centuries ago we'll see

what marty and alex see and decide what to do i went down just fine i descended

just right i got to the bottom i saw the stone it was not that big but it was

certainly triangular

After spending several minutes looking at the strange-shaped rock, Marty and

Alex return to the boat.

Meanwhile, diver Tony Sampson continues searching for a possible connection

between the triangle-shaped rock and strategic areas on Oak Island.

I am not a well-balanced diver, okay? I'll tell you that right now.

You saw it, right?

Oh, I saw it. It was big.

Okay.

I looked at the rock pretty carefully. It's definitely triangular-shaped,

you're right. But I thought it was all... I mean... Does this sound about

right to you? About like that?

Um, maybe it's as large as that.

Yeah, it was definitely elongated on one side. Yes.

You know, it's triangular. I see why you said this is it.

All right, well, mystery's still mystery.

Yeah. Although,

as far as Marty Lagina is concerned, The results of the dive have proven

inconclusive.

Tony Sampson continues his search along the ocean floor.

He is not convinced that the rock Rod Peterson located earlier is the same

triangle-shaped object the team has been looking for.

Suddenly, Tony spots an unusual stone object covered with vegetation.

Tony, let me help you with your kit.

So where the hell did you go?

Oh, I took a bit of a swim.

I got something to tell you when I get up. Get up here and tell us.

Tony had logically decided to follow the magnetic north bearing from the first

stone all the way to shore to see if there was anything lining up.

All right.

Well, so what I did was when we went down on that initial triangular rock

there, I swam that northerly bearing like we talked about. Yeah.

and from the little rock it was approximately 20 meters and i came

across another big triangle rock okay well the strange thing or the weird

thing marty is uh both those rocks the one you and alex dived on and the um and

the bigger triangle rock as well they're both on that same 360 heading you know

going north pointing straight towards the stone triangle on the shore in the

money pit

Do you make heads or tails out of that, Craig?

No, I mean, it's getting shallower, right? Has it got to that big one?

Yeah.

Shallow enough to have been aerially exposed if you throw an erosion?

Maybe. Maybe. You'd have to throw an erosion for sure.

Yeah.

On a recent trip to the Bedford Institute of Oceanography in Halifax,

Alex Lagina, Jack Begley, and island historian Charles Barkhouse were eager

to find out if, several hundred years ago, the Oak Island shoreline could have

had a much different shape.

In the past, sea level was lower, probably a meter or two lower, 300 years

ago or 400 years ago.

So probably the shoreline was out somewhat.

So the Bedford Institute added validity to the shoreline issue.

Not only did the sea level come up, but it's highly erosional apparently near

where we're working.

So the stone that Tony found, if it was placed by humans, would have been above

sea level at the time, or probably above the low tide mark.

So if you think about it, that would be a great way to conceal a marker for only

those who know. One stone you can see, one stone you have to find underwater,

and then you just set a buoy on that one, and then there you go, there's your

sight line.

The team has now found two more possible clues that might help them solve the 220

-year-old mystery.

Clues. that might provide further evidence that the treasure really can be

found at the exact place where the stone triangles point in the oak island

money pit i

guess i have high hopes for

this yeah i do too i think he's going to go in one end come out the other end and

say no problem wow that would be fabulous Then he still has to, you know,

get his courage up to do the actual dive, though. Yeah.

Here we are.

After weeks of preparation and an exhaustive search for someone willing

and able to attempt the dive down 10X, the team is hopeful they have finally

found the right person for the difficult and dangerous job, professional deep

wreck diver Harvey Morash.

This pipe is one inch less in diameter. It's 26 inches in diameter.

The real pipe in the hole is 27 inches.

If he gets through there, he should easily get through the other one.

I'm ready to go.

Okay. We want to see that big thumbs up.

Okay. I hope I can give it to you.

For Rick, Marty, and the team, the stakes of this test dive could not be

greater.

They are determined to send a diver down to the bottom of borehole 10X.

to see if as their friend and partner dan blankenship maintains there really

exists a man-made treasure vault complete with a mysterious chest and

possibly the remains of a dead body lying 235 feet below the island surface

we have some trepidation because if he doesn't fit through that pipe then this

method is basically off the table i mean it's pretty much as simple as that He

has to fit through and he has to fit through comfortably enough to attempt

the dive.

So, you know, we're a little concerned.

He's trying it first with his full normal setup, but then he's got

different stuff if he doesn't fit.

I'm hoping he fits with his normal setup because that would be the safest.

harvey has made it into the 26 inch wide steel casing however he will still need

to maneuver through the narrow hole without damaging his equipment or

getting stuck i can't see him

come

on let's see them bubbles come out the other end close right now

He's out.

Yeah, I still want to see that big grinning thumbs up. Then I'll say it's a

done deal.

There he is.

Thumbs up? Did you do it?

Does that just mean you can breathe?

Put it this way. I'm glad I didn't have a big lunch.

Really? That tight?

It's snug.

Is that your full kit you got on there? That's what I would wear.

Do you have enough to where you want to do this dive?

We want to cross 10X off the list.

And the exciting part will be if he says he's willing to go down there, I think

we'll accomplish our goal.

Yeah.

All right.

So that's the point anyway.

That's great. We got a guy who can do the job. I think so too.

Go in. Have some more fun. Thank you.

Let's move on.

Done? Come on, guys.

It is the end of another long but productive day on Oak Island.

And now, less than 24 hours before Harvey Morash attempts his critically

important dive, Rick, Marty, and their team meet with Oak Island researcher

Jeff Irving.

He has traveled all the way from New Brunswick, Canada, at the invitation of

Jack Begley, who, after hearing Irving's compelling theory, thought it plausible

enough to share with the entire team.

Thanks for having me, fellas.

I think one of the hardest challenges in any conversation is to get to the truth.

I dig like a dog with a bone because I want the truth.

You know, I've been at this eight hours a day.

This is all I have done for the last year and a half.

Basically, I've connected the dots.

Well, start with your first dot and bring us down the dots.

Well, I was researching treasure, but then, you know, I said, what's all the

effort about? It can't be about pirate gold. Too much effort, too many people

involved over time, too much secrecy.

What I think we're looking for is the Ark of the Covenant.

The Ark of the Covenant?

the gold-covered chest which held the Ten Commandments?

Every time somebody says, you know, I've done this study and I've determined that

the Ark of the Covenant is buried over here, you get this sort of little

frisson of excitement because, you know, he does believe and I want to believe.

And so you get these people telling you there's these immense riches on Oak

Island and you get kind of excited about it.

To me, everything's together.

All these religious artifacts, if they've been guarded up until, you know,

the time of the destruction of the temple, then there's 1,500 years worth

of successful guardianship.

One of the aspects is who is involved, okay?

There's a lot of people involved.

Templars are involved.

Masons are involved.

You know, there have been other theories that have proposed that Henry Sinclair,

his voyage supposedly over here, do you buy into that?

Personally, I believe in the Sinclair coming in 1398 because it makes sense.

I support it, just not that he brought anything with him, okay? I think he was

the scout.

At this point, I will tell you that I believe Christopher Columbus.

was responsible for the Ark coming to Oak Island.

At this point, I will tell you that I believe Christopher Columbus was

responsible for the Ark coming to Oak Island.

Christopher Columbus?

The famed Italian explorer credited with discovering the New World on behalf of

Spain in 1492?

Could Columbus's mission to the New World have also had a secret motive to

hide one of the world's most sacred religious treasures on Oak Island?

The only known portrait of Columbus with any accuracy shows him showing the

symbol meaning the Word of God.

Christopher Columbus was supposedly related to the Sinclairs. Of course,

Sinclairs have the Templar connection.

Christopher Columbus has other Templar connections as well.

According to Jeff Irving's incredible theory, Christopher Columbus was

directly connected to the Knights Templar through his wife, Felipa Moniz

Perestrelo, a Portuguese noblewoman.

Her father, Bartolomeo Perestrelo, was a Grand Master in the Knights of Christ.

which was a Portuguese incarnation of the Knights Templar.

Perestrelo was also related to Henry Sinclair by marriage.

Although both the Knights Templar and the Knights of Christ were frowned upon

by the Roman Catholic Church, many of the Portuguese explorers of the New

World were members, including Vasco da Gama, the Corte Real brothers, and Henry

the Navigator.

It is for this reason that they, along with Columbus, sailed across the

Atlantic to the New World with the Portuguese version of the Templar Cross

on their sails.

The same cross that area historian and stone carving expert Terry Duvaux

identified as being similar to the one carved on the so-called Overton Stone,

located 144 miles southwest of Oak Island.

This particular shape of cross is not all that common.

where you have the flaring outwards of the arms. You mainly see it in

Portuguese crosses.

Is it possible that based on his connections to the Knights Templar,

Christopher Columbus knew of an island in the North Atlantic that had secret

tunnels designed to hide sacred treasures?

Pretty much every step he made was documented.

And who did he bring it here with?

A gentleman by the name of Juan Perez.

Juan Perez was the accountant of Queen Isabella. She was one of the two people

that convinced the Spanish crown to fund the expedition.

But he disappeared once he got here. All trace of him is lost.

You're not going to lose the main guy that helped you get all your financing.

Marty, would you lose track of Rick?

No. Exactly. No matter what, you're going to cover his back.

What was he doing while he was lost?

I don't know.

He was up here burying the treasure. Who helped? Who also disappeared shortly

thereafter, long about 1503?

The Real Boys from Portugal.

In 1501, Portuguese explorer and knight of Christ, Gaspar Corteiro, reached

what he called Terra Verde, or what is now known as Greenland.

It has been reported... that he then sailed south, never to be heard from

again. One year later, Gaspar's brother Miguel, who was also a member of the

Portuguese Templar Order, reportedly went to find him, and he too

mysteriously disappeared.

Is it possible, as Jeff Irving believes, that the two brothers did not go

missing, but instead were part of a secret Templar plan to hide sacred

religious treasure on Oak Island?

If you guys buried the treasure here, are you just going to walk away and

leave it?

Assuming that the ground is going to look after it and nobody's going to find

it?

You're just going to walk away, sail away into the sunset? It matters what

our intent is, I suppose.

If it's the hiding spot, why would you? You're going to stay and you're going to

guard it.

You're going to disappear from history.

You're going to make friends with the Aboriginals, you're going to blend in

with them, you're going to marry them, and you're just going to disappear into

the New Guardians.

You have the cross with the circle, the eagle feather, and behind the eagle

feather there are a pair of tobacco leaves.

There you have a friendship treaty between Europeans and Mi'kmaq.

It is my theory that what you're looking for is actually the Ark of the Covenant.

And I believe it was smuggled out of Jerusalem by the Knights Templar where

it went to Scotland and then it was brought here by Columbus and Company,

you know, in 1500.

Well, you know, Jeff, I mean, it's always interesting to meet a theorist,

somebody who has spent the time and due diligence in terms of research. I think

we've all learned something today, and so let us look into it. It's a lot to

digest, but we're very, very grateful. I think we all are.

Might it be Jeff's theory?

Maybe. But it's like all theories. Could it be? I suppose.

Could be.

But it's a theory. Right now, as we sit here, it's a theory.

I appreciate the time.

hopefully it'll be good for you thank you very much

it is the start

of what could be the most important day in the history of oak island as rick

marty craig and the other members of their team once again shift their focus

to getting a diver to the bottom of 10x

We're off to put divers in the hole. Rick, it happened. Not happened yet. No,

but it's happening.

Make it so, then.

We got the right guy, I think, the right crew, the right backup team. We got

everything right.

With any luck, we get a human being into the 10X cavity.

Kept everything warm and ready for us, have you?

Nice to see you again. Good to see you.

You know, what do you think, Charles? I mean, today, you know, this is the

beginning of the end of 10X.

Explore that cavity completely.

Then? Then. Then call it a day.

Who's not excited? We're getting answers to a 40-year quest.

I thought every time we got inside this fence, we're supposed to be wearing a

harness, right?

What's in the bottom? You know, thumbs up, which I believe it will be, or

thumbs down.

It's the beginning of the end of 10X.

See the 10-inch there, Harvey?

Yeah, the 10-inch over here. Right, and it's shackled here.

See that? The 10-inch in the middle of the hole. Yes.

After months of back-breaking preparation and years of planning, Rick,

Marty, and their team could be just minutes away from finding out if a man

-made treasure chamber really does lie at the bottom of 10X.

We'll get everybody over here for a minute. We're going to have a little

safety talk.

Okay, guys, the objective of this dive is to give it our best. We can't make

any promises.

Assisting Harvey Morash will be Michael Gerharts on the audio communication

system. and dive supervisor, Janine Goyesh.

However, only Michael will have the comm system connected to his dive helmet.

Everything comes through Janine. Everything comes through Janine. What

she says goes.

End of.

Any questions on that?

Okay. Now we do have some hazards, and pretty much any of these will end the

dive immediately and we'll begin our ascent.

Some of the hazards are equipment malfunction, our scuba gear.

or the comms, anything like that, dive is over.

Where's the comms person going to be?

The comms person, I guess she should be undercover here.

As close as she can get really undercover, if we have to move the tent

closer than that, that's fine.

Who's going in first?

Apparently I'm going in first.

Okay. The plan is that Harvey's the guy who's going to go in the 27-inch.

Michael is the backup guy, the communications guy.

The safety guy who's gonna be there to help I guess literally pull Harvey out

if it comes to that So we're gonna try to be as efficient as possible, but as

safe as possible We can't eliminate risk, but we can mitigate it. Hopefully

we've set ourselves up for success And we have a good dive because I want I

want to get in there and see what's going on To help prevent him from

getting tangled up in possible debris or other obstructions Harvey will not rely

on a surface supply breathing system.

He will also not be wearing a comm system, which would allow him to talk to

the surface.

Instead, he will wear two scuba tanks with a tri-mix air supply and will

communicate directly with his safety diver, Michael Gerharts.

All right, guys. Get me up. Get me in.

Harvey is lowered into 10x first.

Michael will follow him down, but will remain at the 181-foot level, attached

to Harvey by means of a single tether line.

Going down.

Watch my back, please.

Yeah, that's what I'm concerned about, is tanks hitting on anything.

As Harvey descends and explores the shaft, he and Michael will communicate

with each other by giving short tugs on the line.

Watch your back, Harvey, for that 10-inch.

The only thing we have is Mike's communication to the surface. Harvey

will not have any communication devices.

So we're going to really kind of get a secondhand blow-by-blow, and we're

anticipating low visibility.

So we don't have real good real-time feedback.

You're all set.

Go.

Good? Just give him a minute.

Okay. David, have him up.

You good? Yeah.

Okay. Let's go.

Keep going down.

Both divers are in the water, and Harvey Morash is on his way to being the first

person to successfully reach the bottom of 10X in more than 20 years.

But once down there...

What will he find?

Manmade tunnels?

A treasure chest filled with pirate gold?

Human remains?

Let me know when he's fully under.

Or will he find that Oak Island's secrets really are protected by a deadly

curse? He's under.

Johnny, can you hear me?

I can hear you. Can you hear me?

Do we have communications?

Michael, do you copy?

Johnny, can you hear me?

Next time on The Curse of Oak Island.

Okay, take me up. Up.
