Enables tech divers to use two or three different gas mixtures. Calculates desaturation time so it could be used as time to fly. Instructions are incomplete and poorly laid out. Not well-suited for general recreational diving. No back light, but does glow when exposed to light.
Audio alarm is very faint.
Default when in nitrox mode is 99 percent oxygen and 79 percent nitrogen, thus creating a complex set of problems. The NiTek3 can be set for one, two or three different gases of 21 to 99 percent oxygen. These computers are conservative on shallow single dives, liberal on single deep dives and average on multilevel dives. No prompt card is supplied, but some information is given with a sticker on the inside lid of the carrying box. The Dive Rite NiTek3 has the most confusing, perplexing and problematic instructions and procedures we have ever found while testing dive computers, an honor they share with the Sherwood Scuba AWAC-1.
