Hi All
Doing my TDI Entry Level Trimix in the new year (because I'm starting to forget things below 40m
). My parents are buying me some (more!) dive kit. Existing stage is a steel 5, thinking this could make a drop tank? So, new stage(s), initially thinking 1 stage but is it worth getting 2, but do I go 7's or ALI40's? definately not ALI80's, they're just toooooo big
40 = 5.7litre @ 207 bar = 1150 litres approx
7 = 7litre @ 232 bar = 1600 litres approx
Remember I haven't done the course yet, but if I run a bottom time of say 40 minutes at 50m, END of say 30m (don't know what mix/deco that would give me?), would a single ALI40 be sufficient? (my SAC is 15 on a good day) Also take into account I like to be self-sufficient and hide away from all those box divers, they always look at me funny, on the last trip, I overheard one calling me his bailout
Cheers
G
