Dive 2 - Let's see how far we can go
As we are exiting from our previous dive, our third team member for dive two shows up. I setup my tanks, and have lunch while he is gearing up. He will be diving sidemount AL80s with a stage bottle, so we discuss gas planning since now we have a dissimilar configuration. Next we discuss the dive plan. Since we still have the reels at cisteen and Nicholson we plan to head down Nicholson, let our new team member look at the T and cookie it, and then head down the cisteen line to see how far we can go. Since I had a little deco on the last dive I decide to bring my deco bottle.
We gear up, do our pre-dive checks, dive briefing and start blowing bubbles. I head down and slip my deco bottle to our line, circle the restriction ok, get a response back, and down we go. I do the same stop at the bottom to give my team time to catch up. Once the team is down, ok everyone and off we go. A couple hundred feet in I realize that it is hard to see our new team member's light so both Chris and I turn down our lights. Again pretty uneventful swim to Nicholson. Once in Nicholson, I try to stay higher to avoid puffing, I'm going to have to develop a better sense for being so high as I was contacting the rock with my fin more than I would like.
We make it to the T with cisteen, our new team member cookies the planned exit side of cisteen, and we head further into cisteen. We pass the big red arrow, I stopped to examine it, but I made the mistake of not doing the circle to notify my team members. Our new team member helpfully points that out, which annoyed Chris a little as I would've earned a drill because of that. Next we made it to the cisteen T. We didn't brief this because I don't think he tought that we would get this far. I figured we would go up to cisteen because I like the idea of popping out of another hole. After a brief "discussion" we go further into the cave toward Wishbone IIRC, we probably get another couple hundred feet beyond the T before our new team member signals me that it was time to turn the dive, which wasn't much sooner than I would've turned it, I think I had maybe a 100 psi left of my 1,100 third.
We briefed that I would remain in the lead for everything except reel work, so I swam in front of the group. Sometime after the cisteen T, but before the Nicholson T, Chris signaled me and told me that my primary light failed. I clip it off, shut it down, and pull out one of my back up lights. As we swim along we pull our cookies at the Ts. Once we get to the end of the cisteen line, I signaled the team to swim ahead of me, once they were ahead of me, I pulled the reel. Get to the mainline, store the reel, signal the team and proceed down the cave, acknowledging the double arrows as we pass them. Next stop was the Nicholson reel, I stop, turn around, signal "hold" get the reply and them swam over to pull the reel. Same procedure as last time, and we continued I pulled a final reel that we had placed when we went "exploring."
As I swam the last couple of hundred feet I noticed that all my reels were clattering together. We make up to the mainline to the cavern zone, I pick up my deco bottle, and pull the primary reel. Once the primary reel is stored I switch to my deco bottle, this was a much longer dive than any of us expected and I racked up 7 minutes of accelerated deco. Once I was done with my deco, Chris briefly considered using my deco bottle, but decided against it as the new standards don't allow for that. So we stayed down and stacked rocks while he did his 20 minutes of deco.
In water deco done, we ascend to do our debrief while doing surface deco. The only real comments were that I needed to work on keeping my team a little closer, which is why he failed my primary light, and of course the mistake at the red arrow. Beyond that it was a pretty clean dive. He also mentioned that it was the farthest he has seen a student take LP85s, which was probably why we didn't brief the cisteen T, or expect as much deco.
