BRUCE K It seemed like a good reference to have for the price. Not a lot of tables out there for nitrox

DUDLEY M Which dive table you select depends on what you are looking for. Personally, I prefer tables to electronic calculators because a table never runs out of batteries and won't get ruined if you accidentally drop it into the water. Obviously the choice between 32 and 36 depends on what you dive most often. But the mathematics for conversion is fairly straightforward. I hope this answers any questions you may have.

NAT A because I teach PADI's Nitrox courses and want relevant tables and info around.
