Abyss just came out with a Mixed Gas Submersible Dive Computer, check it out!!!
It's too expensive though.
If you're one of the lucky ones to have tried it, e-mail me, I'll put your comments here.
They have a demo which goes down to 100 ft.
Created by Totek, this excel based dive planner uses IANTD dive tables, has plans for using several bottom gas nitrox mixes and includes accelerated decompression capabilites using higher oxygen nitrox mixes. If you're overwhelmed by the Dive planners listed on this page, check this one out.
It's easy to use and understand, it'll run on most systems so you can even put it on a palmtop to take with you anywhere,
Hooverman does excatly this. It's also ideal for those who will be taking up Advanced or Technical Nitrox with IANTD, the interface looks like the IANTD log books.
Just plug in your depth, time, bottom mix, deco mix and rmv; and it'll give you your decompression schedule with the volume of gas required and your residual nitrogen, CNS and OTUs.
For the next dive, just plug in your surface interval and you're ready to go.
I've edited the program to generate Plye Deep Stops and added an IANTD air table with 75% deco.
I'm also putting up a collection of Do-It-Yourself projects found all over the net.
