NARRATOR: At the money pit site, Rick Lagina, his nephew Alex,
and Craig Tester, along with representatives
from Divetech Ltd., are just beginning
a Sonar scan of the H8 shaft.
They are eager to obtain more precise imagery
of a large underground anomaly that was recently identified
by seismic scanning, an anomaly the team is hoping
could actually be evidence of a large underground treasure
chamber.
OK, Joey, carry it on down.
Yeah, roger.
NARRATOR: Using motorized propellers operated remotely
from the surface, the sonar-equipped ROV
descends the 50-inch-wide HH steel caisson toward the soil
and possible void below it.
So once we get out of the caisson,
we should see the change from a hard yellow to a softer return
because the clay will be absorbed in the Sonar.
Mike, if there is a void, or a tunnel, or anything down there,
what would we see?
We would just see an open with no return.
There's no video now.
It's just black water, so that's what I expected.
So we're down 20 meters now, so we're just passing 60 feet.
We're coming onto 50 meters or 167 feet.
And that's going to be the bottom of the can.
Let's get a scan rate in here.
OK, Joe, coming to a stop just doing a scan.
Roger that, Mike.
I'm waiting for Mike to have the aha moment.
I'm waiting for him to say, there.
There's what you're looking for.
Did you see that?
See the square corner?
That doesn't go round.
It looks like it comes in an--
just at an angle.
See that?
MAN: There.
Let me go back to 2 meters.
That is something there.
I think so.
See that now?
That is a clear right angle.
We can definitely say that's a 90-degree angle there.
NARRATOR: A right angle?
Could the team actually have found
evidence of a man-made chamber located
some 170-feet deep underground?
Is it possible that you're at the site
of a rather large cavity?
It could be.
NARRATOR: If a large void really does exist
some 170-feet-deep underground, has
the Oak Island team finally located the bottom
of the original money pit?
And if so, could they be just moments away from locating
the legendary Chappell Vault?
- 100,000 pounds, is it? - Uh-oh.
MAN: Yeah.
MAN: That doesn't seem right.
That video is dropping out.
JOE: Like your screen's flickering?
Yeah, roger that.
MAN: Uh, that's not good.
OK, so I can't put autodepth on,
and my video is flickering for some reason.
Yeah, video is flickering really bad.
Yeah we've lost sonar as well.
No more power?
That is odd.
Everything started shutting down.
We got a comms loss alarm.
JOE: OK, well, you may as well power down.
Pull it, and take a look at it.
MAN: Yeah.
Yes, and if you think it can be fixed real quick,
let's go right back to where we want to be
and see if we get some data.
Joe, just pull her up, OK?
JOE: Roger.
NARRATOR: Although the ROV was built to withstand depths
of up to 1,000 feet, it would not
be the first time that equipment suddenly and inexplicably
failed on Oak Island.
For the past two centuries, treasure hunters
have reported bizarre equipment failures and usually
at times when they believed they were
close to a major breakthrough.
Could this be another such occasion?
MAN: OK, you're on surface here.
Going to pull you out of the can.
I'll see if there's any water in this.
Hopefully there isn't.
MAN: Did it flood?
Yeah.
MAN: It is flooded?
MAN: Yeah.
MIKE: That's not good.
MAN: Yeah.
That does it for us, then.
MAN: What are you thinking?
Dig.
NARRATOR: Because it is Mike and Joey's assessment that the ROV
has suffered serious water damage,
the Oak Island team will be forced to suspend
today's Sonar operation.
Nevertheless, evidence that a large, possibly man-made void
exists at a depth of 170 feet has
made them more eager than ever to hammer
grab the contents of H8.
Danny.
MAN: About time you do something, son.
It's happy time for you.
You got to do something.
We would like to hammer grab you today,
and we're running out of time.
So fire it up. - OK, thank you.
I appreciate it.
MAN: Unbelievable.
