Just back from another day at the Cenotes, this was another trim buoyancy and propulsion day but more in the water today, more changes to my rig and yes a bit more cut off but only really to make it look prettier.
Nando explained today how he was going to be 'nasty' too me for the next week, unlike PADI course where everything is positively enforced with a 'high five' or a hand shake when you get something right. The Cave course they only bollock you when you do it wrong and make you keep doing it untill its right :) Bit like being in the Marines then!!
So trim is being level in the water, with your feet up from the knees so you dont move any sediment, Buoyancy is basically staying in the correct position in the water in the correct trim. Propulsion is learning the correct cave diving fin techniques, one of the hardest things to learn today has been going forward then stopping dead and then actually reversing which is something I didnt know was possible and it seemed impossible for the first 15 minutes!! its still not 'pretty' but I can do it (a bit) I am told I will be good at it by the end of the next twenty dives :)
Had a beer with Jason after we got back to the centre, he's a great guy and I'm hoping to do some dives with him after the course. Nando was telling us all about the Bull Sharks that visit in December, you can dive with 7 to 10 at a time, which sounds amazing, he also told us the story of his trimix dive where a 4 metre Tiger Shark kept them company for 45 minutes and came upto them 3 times so close he could see it breathing!! Very scary!!
