The Perdix AI took the standard Perdix’s AA-battery, tec-focused design and added wireless air integration, without changing the external size or shape. It’s since been succeeded by the Perdix 2, but remains a common sight on tec and rec-tec crossover divers.

"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.
