I want to start out by saying I am a recreational diver NOT a tech diver but have some questions to see if a tech course is something I should pursue. I live in Illinois and do a lot of mid west diving. It seams that many of the things I find my self interested in going to see are in 100-140 ft in lake Michigan. However at 120ft only having 13 min of bottom time seams like a lot of work and time for 13 min of bottom time.
I have seen some OLD deco stop tables that im assuming are before nitrox/trimix etc and I am wondering what I would be getting my self into. I would assume I would go to Dual back gas + stage bottles which means loosing the BCD and going to a wing and back plate.
I guess my main question is lets say I was going to go to 120 ft and had a bottom time of 45-60 min. How many different gasses will I need and what would my deco stops and times be. I see a lot of guys in LM with Dual Back gas and 2 stage bottles, but have seen some with dual back gas and 4 stage bottles. I have heard of some CRAZY long deco stops and hanging on a rope for 60 min for a 60 min dive does not sound fun either. but I have heard with mixed gas those stops are much shorter.
can someone give a conservative example of a 120ft dive with 60 min bottom time?
