In November I was finally able to complete my underwater video system. It consist of a Sony FX-7 Camcorder in an Equinox HD8 underwater housing. Lights include Light Monkey's Dual 50 Watt HIDs. This is mounted on a short body Gavin scooter. Total combined weight is about 135lbs out of the water. In the water it weighs next to nothing. That is the goal anyways. Here is a picture of the system.
