Capture that sudden or last minute shot in or around the water with the AquaTech Pistol Grip Trigger System and your Delphin 4 or Elite 800 sport housings for the Nikon D4 or D800/D800E DSLR. Featuring a depth rating of 33', the pistol grip trigger allows you to aim and maneuver the housing and shoot with a single hand, without camera shake. Constructed from polyurethane, rubber, and stainless steel, the system mounts onto the bottom of the camera with ease. The grip is light and ergonomic in your hand and the waterproof shutter release switch is very sensitive and direct. The system also comes with all mounting hardware, wiring and a coiled, extendable cable release. It's great for reaching extreme angles and ensuring that you make the most of your privileged access to marine environments.

This device offers both a shutter control and focus control, yet zone focus is recommended for sharper, more consistent images. The trigger will work in both single-shot and continuous shooting modes and is powered by the camera, so it requires no battery. AquaTech products are designed for shallow water and surface use, and shouldn't be operated at depths beyond 15' for longer than five minutes.
