RJP- Correction, I made a slight error yesterday, after going over my tables later I relized that it is 4.94, and not 4.30, so the calculation for my correction comes to: 16.00x4.94= 79, now 3000/79= 37 mins (still close to 40) with a single AL 80 (w/o reserve) as for no deco still that means if you dive air than 10 mins max, with EAN 32 (according to an EAD of 110') that gives you 16 mins, so no I can't stay at 130' for 37 mins and expect not to get bent, I would need more gas for a reserve, and gas for deco + a plan for the deco dive.
Please read my words carefully and try and understand what I am trying to say..
After reading your posts and reply to posts it seems like deja vu.. ABout 10 years ago a dive club I was helping run had a very enthusiastic 16 year old diver.. When he dove with us we always had an experienced diver with him.. His skills were excellent but being a 16 YO, decision making and feeling of invincibility were what you yould expect from someone that age..
This diver collected alot of recreational specialties, the decided he wanted to take on more challenging dives, Myself and several otehr divers tried to convince him to slow down and have fun... I tld him I'd do his technical training when he was 18... Well that was the last thing he wanted to hear.. What did he do.. He found a TDI instructor and got a waiver to do decompression training (I believe he was the firsts case).. He did his training quickly.. While he dove with us we kept him within recreational limits, He dove with another group and got bent, basically beacuse of a bad decision.. a few weeks later he dove of another boat with his tech instructor where basically everyone is on their own..
To make things short, he got himself entangled and paniced.. He lost his reg and was technically dead.. He was found by another diver and brought to the surface and revived.. He spend several months in a hos[ital learning how to do basic things like feed himself and walk.. He needed 3 weeks of byperbaric treatments and was left with permanent anurysms in his brain.. By this time he was about 17... He was told NEVER to fly in an airplaine or risk a rupture of one of the anutysms and to NEVER dive again....
Take your time, Have fun you have alot of time ahead of you, and find a good mentor on the types of diving you want to do...
