The Genius is built around a large color display and heavy multi-transmitter air integration, aimed at divers running more than one tank or stage. Mares pairs it with adjustable gradient factors on the standard Bühlmann algorithm rather than its older RGBM implementation. Street pricing swings widely by retailer and bundle, expect somewhere around $570–$800 for the computer alone.

"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.
