The Atmos Pro is a Best Buy. It has an extended deep-diving algorithm. The instructions for the Savant are excellent, but not as well laid out as those for the other Aeris computers. 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.
