The NERD 2 is Shearwater’s near-eye display, built for divers and rebreather users who’d rather glance slightly down-and-in than break trim to check a wrist computer. It runs the same Bühlmann/VPM-B algorithm choices as the rest of Shearwater’s technical line, in a case shaped for regulator or CCR loop mounting instead of a wrist strap.

A heads-up regulator-mounted display for divers who don't want to look at a wrist.
Open BLE sync (libdivecomputer)
Syncs wirelessly with third-party apps (Subsurface, Currents, etc.), not just the manufacturer app.

"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.
