The Axiom i3 uses a wrap-around air cell and form-fitting harness for excellent stability. Swiveling shoulder buckles and a thin back plate keep the diver’s tank properly aligned and improve weight distribution. The result is easy maneuvering on the surface and a BC that won’t ride-up while in the water. The Axiom’s i3 inflation system uses a toggle switch instead of a traditional inflator hose. Lift the toggle up to add air. Push it down and both dump valves open at once. This allows buoyancy adjustments at any swimming angle. Divers will also appreciate multiple cargo pockets and the easy-to-load Surelock integrated weight system. In back, the GripLock Tank Band system makes for easy cylinder changes with pre-set adjustments, and has an innovative finger saver feature. The Bottom Line: The Axiom i3 delivers in-water stability with creature comforts every diver will love.
