The Excursion is Deep6’s own-brand budget computer, shipping in a stripped-down recreational mode but with a free firmware download that unlocks trimix, up to 11 gases, and CCR bailout for divers willing to flash it themselves. It’s Deep6’s only in-house dive computer. The rest of their computer lineup is Shearwater and Divesoft gear sold under the Deep6 storefront.

"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.
