Suzie could not get the time off work so I did my first few rebreather dives without her for quite a while. I was diving my TOPGUN unit with a 19cf oxygen cylinder and 40cf air cylinder on my back, and a 80 stage of about 30% Helium, 23% oxygen bastard mix as my diluent/bailout. I also had my Predator 2000 up and running, it sure beats swimming against the flow in Ginnie Springs. The 1st dive we scootered to Sweet Surprise which is a scooter / swim dive somewhere up the gold line in the 1000-2000 foot range. We did not make it to the place we wanted to see, one of the team members reaching 1/3rds. So we swam out to the scooter drop on the gold line at 40-45 minutes, and I waved the group good-bye and scootered up the gold line, where I dropped my scooter at the Hinkle/Rouse restriction. I swam upstream from there just past the 3600ft line arrow; the cave get smaller back there, and the flow proportionately stronger. I scootered on out for a 125 min bottom time at 100-110ft, P02 of 0.45 to 0.9, and did 25 minutes of deco PO2 of 0.8-1.0 at 20-50ft. The second dive we hooked up with an Australian named Chris who is working at Ginnie Springs dive shop. He brought back memories of the total strokes in the CDAA (Cave Divers Association of Adelaide) with his stories of refusal of permits to dive despite his US cave cert.. I am definitely pushing for all CDAA divers visiting Florida to complete US cave training from cavern thru full cave before they are allowed to dive here, an a purely reciprocal arrangement for this very requirement of Chris, who is Full cave in the US. Unfortunately on this dive to the insulation room, his torch crapped out and Evie had to escort him out. Anyway after we dived the insulation room, I again waved good-bye to my OC buddies, and scootered up the Gold line in search of some jumps to the right. Unfortunately, after several scooter drops, all the lines turned sidemount and I had to scooter further upstream. Eventually, I found a jump with a nice ledge to drop my scooter on, and I ended up stumbling on a dive I have been wanting to do for a while: a bit of the cave called mainland. Mainland was an excellent dive, and I definitely want to get back in there again with Suzie, and a spare 80 stage waiting outside "just in case" despite a single 80 being enough gas to swim out from the furthest point I eventually turned at, 3900ft. Turned at 80, 105 bottom, 10 deco. After this dive I put Evie on my rebreather for a while, she dropped down to 30ft in little devil and did pretty well considering the differences from OC, and 2 minutes of pre-dive instructions. She will be diving with us with our spare rebreather real soon. The last dive Evie and I planned to dive Mainland, and Evie prepared with a 80 stage so we could do a good bottom time once in mainland. Unfortunately, at about 1500ft, the clutch failed on her scooter, and I had to tow her out to what I know as snap and gap, although the bungy gap line is no longer in place. There we dropped her Predator 3000 (My mother in law has a bigger one than me) and I towed her up to the jump to the double lines, where we did a circuit thru the double lines. My rebreather came in handy in the bedding plain section here, it is lower profile than a single 80. One thing I was amazed at was that I seemed to loose no speed scootering when towing Evie, double 100's, an 80 stage and another scooter. She used the WKPP technique of tucking right in, but I still scootered quick when she stuck her head out to see where we were going (and give me directions!) This dive was shorter than the previous 2, and I ended up with 6 hours in water time on my scrubber.
