As previously mentioned  Computers fail so you need some form of redundancyy and ratio deco and a simple depth and bottom timer works out the chepest way to go about it. |
Mark, I would like to jump on your band-wagon if you don't mind
You are always going on about the GUE crowd recommending RD as a panacea without explaining the limitations/risks. We counter it by saying that you really need to know the whole picture about doing RD (mixes, ascent rates, deco gases etc). Please do not undertake RD unless you have a good idea of everything that goes into RD.
In your case videogirl, I would recommend using a bottom timer and tables to start with (as that is what you are going to do on the course) and then once you have an idea about where you are going in deco diving, then choose a computer to match your aspirations ie single gas, 2 gas or a full blown VR3.
