deco time on 99% 02

[deepdiver4]

do they make a chart 4 100 02 or how would you calculate how long your deco would be. not relying on your computer ..

If you're diving a single gas between 30% and 36%, deco on 100% is almost exactly half of what it would be on your bottom gas.

Yes, you can buy tables which have 100%, or 80%, for deco or you can use dive planning software to create tables (inserting your deco mix for dive planning).

Go to Iantd website at www.Iantd.com then click products,and finally charts and tables,for the foldable deco tables.You can also email them to specify a certain chart if you dont see it on the list.

With the number of very reasonably priced software packages on the market there is no reason not to cut custom tables if you are not using a computer that handles gas up to 99%.

I use v-planner and a Vr3.

Well then, maybe you should be called "shallowdiver4" Just jokin' YO--in all seriousness, listen to Sludge -- that's about as quick and easy as you could ask for, eh?

I dive with two duos and am very happy with them, but have noticed that one must hold the button in for several seconds before the computer switches from gas 1 to 2. In other words, make sure it has really switched to gas #2, unless you want to be really conservative and breath O2 based on backgas deco time. Obviously the real hazard would be to switch the computer and not switch gases.
