Day 5 & 6
On day 5 we started preparing the "big dive" . Today was also the day the concept of ratio deco was thoroughly explained to me. The coolest thing was that i understood it. We also looked at the various digital planners that exist in the deco world and they sometimes give you outputs that are difficult to remember so basically I learned a little bit of Kelvin, deco planners and ratio deco. Put that in a mixer et voila! our deco plan is born. The plan needs to be simple because remember this is all in my head no slates or wetnotes what so ever. And even at depth where you have lots of shit going on in that teeny bit narced out brain of mine i need to be able to focus and most important remember.
The dive today was all about putting the line in so once again i tied into the tree at 27m ( i am beginning to talk to the tree now cuz he has been involved in my course so much hahahaha) then to the 1st nipple ( actually for me it would be a penis) and the 2nd penis...uh nipple. We basically call it that because the 2 stalacmites are well.. sticking out on a formation ;). his time however we did not stop at the second nipple we actually went through and connected to the cave line at 48M. COOL!
On our way back we actually had some real things happening. Franks tank clip of his oxygen tank broke and off course Kelvin took the opportunity to take the tank away from him which basically menat we only had 1 deco tank (mine) between the 2 of us. On top of that He also decided to run out of air ( this was simulated don;t worry). So we started our ascend which I know had to adapt slightly because we had only 1 deco tank.
In the evening I had homework and I had to plan the dive for the next day to 60m in the cave of Cenote the pit. This is slightly tricky cuz remember this is not just a dive that goes down and then up. Lots of thinking about how to attack the dive and lots of math!! guess what ... i liked it :)
here is the proof:
Day 6
Today is the big day. THE dive.... EXCITING!!! So first I had to present my plan. Kelvin drew it out on the board and guess what.... IT MADE SENSE. happy me. So today I would be diving on a proper helium mix. for the ones who understand it my mix was 18/45.
so slightly nervous (well me) we headed to the Pit one more time. Today would be the dive to 60m and I would finally be able to go into the cave. I mean I had been teased for 5 days now and finally I could get in.
We set-up our gear and I briefed Frank at the beginning of the dive what our dive plan was. So we were both clear on the hows, what and when's. Well me being the students you are actually never sure what they are going to do to you (every time I see kelvin go behind me i prepare myself for the worst. Which cable will leak now or what is he signalling to Frank e.g. out of air or whatever. Once we were both clear on the plan we descended to ... guess what.... my tree :) we followed the line, dropped our deco bottles and FINALLY went into the cave. The cave was a bit blurry in the beginning as lots of bacteria had formed over the last couple of weeks. The bacteria was orange and looked like little tear drops in the water. Really cool effect. I cleaned up after we penetrated the cave deeper. Our turn around point was either pressure, depth or time. In this case it was depth, the line was going deeper than 60m so unfortunately we had to turn around. Narcosis was affecting my awareness ... by me being super aware and constantly looking for Frank behind me. haha
Back at the reel I now had to reel in the primary reel and we picked up our deco tanks. Once we arrived at the my tree we were perfectly on schedule and we ascended. We completed our deco plan , which basically means that you hang mid water whilst going up level by level ( shallower depths).
This course has been unbelievable ( i know i say that after every course) and I learned tons! I actually have realised that that little brain of mine is capable of remembering more than i thought. So after I gained some more experienced I will definitely go on to Hypoxic Trimix. For now I am happy being a normoxic trimix diver (or tecnical cave diver whatever you fancy calling it).
Thanks to a great Kiwi instructor and a great Guate buddy, who for some reason always seems to be running out of air ;)
AYO XOXO
