Why Nitrox?
"All other conditions being equal, a diver on Nitrox 36 will consume about 12 percent less gas than a diver on normal air." - Scuba Lab.
Nitrox computers offer all the same features as the air computers, but also allow the use of Oxygen Enriched Air.
Once a diver's Nitrox is programmed in the computer, decompression limits are adjusted accordingly.
