With the M3 Pistol Grip on your AquaTech Elite II underwater camera housing, you'll be able to hold your rig, focus, and shoot, all with one hand. The grip's trigger controls both focus and shutter in the same way a shutter button does on a camera, press halfway to focus, press all the way to release the shutter. The trigger can also be set to turn video recording on and off. The grip's design is based on the one used in AquaTech's popular AxisGO line of housings for iPhones. It features pronounced finger grooves for good control and a rubberized exterior for a secure, comfortable grip.
