SPL Splash Waterhousing with three ports. A waterhousing meant to be used for water action sports photography such as surfing, sailing, wake boarding, kite surfing, fishing or any shallow water activities. It can be used in the water down to a depth of no more than 20-25 feet. The housing is constructed of ultra light weight aluminum and will withstand the roughest surf conditions imaginable. This particular housing was custom fitted for a Nikon D3 or D3s and will not work with other bodies. The three ports include a small flat port that works with small lenses such as the Nikon 24mm, 35mm and 50mm AF D lenses, a dome port that fits the Nikon 14mm f/2.8D ED AF lens (on sale at https://www.ebay.com/itm/224540298197) and a telephoto port that fits the Nikon 180mm f/2.8D AF lens. The housing and ports allow control of the main command and sub-command camera dials. The housing can be used with a side grip and/or pistol grip. A hand leash is also included. There's absolutely nothing wrong with the housing or the O-rings. The housing has been used in big waves including Pipeline on the North Shore of Hawaii, Teahupoo in Tahiti and Tres Palmas in Puerto Rico and there's never been a single leak. Original purchase price of the entire kit was 00. (Camera and lenses are not included.)
