Sounds vaguely like something I could comment on. The problem I can see is that this setup leaves you with only one source of buoyancy, your bc/wings (if your using one). Where as with an aluminium tank and say a 3 pound weight you've at least got the tank as a source of buoyancy (you can drop the weight). Most I get down to in summer is a 1.5mm shorty and hood. I use an aluminium tank and 3 pound belt with this setup (also because I need to carry extra weight for charter divers I'm looking after and a steely would make me too negative).

Diving mostly with charter divers keeps me within table limits anyway but I use a computer for a bottom timer for the following reasons: 1) As a data logger. I can download temperature data, depth, times, etc directly to the PC. I need these data for a few research projects I'm involved with. Data can be imported into Excel, which is handy. As it's recorded passively if I decide later that I need the data for a particular dive it's available (recording data on a slate while managing a large group of charter divers is often tricky). 2) As a detailed record of my dive profile if any problems arise. Example, last weekend I had a diver who suffered pain during a safety stop and who was in a lot of pain and distress on surfacing. We put them on oxygen and evacuated them by ambulance once back on shore. The pain turned out to be non dive related and minor but had it been necessary I could have provided a detailed dive profile. As the person had been nervous during the dive I had kept physical contact with them during the entire dive and controled the ascent (slow ascent) so the profile on the computer should have been fairly representative. The above would probably not be that relevant to techies, seems to fit my type of diving though. Comments?
