The Mares Air Control is a clever piece of kit that combines your alternate air source and your BCD inflator into a single unit. Instead of routing a separate octopus hose plus a standard inflator hose, the Air Control merges both functions, which means one less hose to clip, route and manage on your dive.

It feeds off your low-pressure inflator line, so the alternate second stage sits exactly where your inflator already is, on your left shoulder. In an out-of-air situation you keep your primary regulator and donate your own working second stage, then breathe from the Air Control, a workflow many instructors find cleaner than fishing around for a stowed octopus.

For recreational divers in Goa and across India who want a tidier, less cluttered rig, this is a sensible upgrade, particularly for travellers who like to keep their setup simple and streamlined.
