Expedition

Okay every everyone, watch your heads as you're coming in. You see that? The black hole down there? - Yeah. -

Robbie

That is the entrance, that's where we wanna go. So, what's our plan here, Robbie? How do we go about tackling this? First going, which should be me in this case, is installing the guideline. So, visibility goes bad, you only have to hold the line in your hand and come back the way we came in. Are you sure we're gonna get in through there? Oh yeah, we can fit through here right there. And from there on, I don't know what we'll find. (invigorating music) -

Steve

That tiny passageway looks scarily tight, but I'm eager for my first exploratory cave scuba dive. We're gonna be the first ones laying our eyes on that new cave there. It's just incredible. It's a feeling you can't describe. Robbie has your half man, your line cutter. The left side is in there. It's gonna be fun to see Steve's reaction to a virgin cave. Be interesting to see how he handles that. Right now, I've got a sense of extraordinary excitement. But that excitement is tinged with nervousness. You know? This is what all the training's been for. This is what it's been working up to is getting in there and exploring. Yeah, I just have to get my head right. (intense music) There, that's got a spare light in it. One spare light. -

Steve

I've got another spare light in here. Line out, clip these on your pipe. Yeah, I'm good. - Awesome. Running through all my mental check lists making sure I've got everything. (intense music) You know, I've done several thousand dives, but I've done fewer than a hundred in caves, and that's not a lot. It's not a lot to be going and exploring and, so this is well out of my league. And I guess we're about to find out if I'm properly out of my depth.
