"Gas switches" is how many different mixes this computer can be programmed to switch between mid-dive, mostly relevant for technical/staged-decompression diving. It doesn't tell you which gas types (air, nitrox, trimix) are supported. See Gas types and the product description above for that.

Pros
  • Hoseless (wireless) air integration in a watch-style case
  • Two-gas switching with independent PO2 alarm settings
  • Nitrogen/oxygen/ascent loading bar graphs for at-a-glance status
Cons
  • Could not confirm whether a digital compass is included
  • Monochrome display only
  • $1,150 price is for the bundle with transmitter; computer-only pricing is lower but unconfirmed

The Amphos Air brings Sherwood’s Wisdom-style monochrome display into a smaller, watch-style case with wireless air integration, aimed at divers who want hoseless AI without stepping up to the Sage’s console format or a color screen.
