It seems that the older I get and the more money I make, the cheaper I become. I have spent many thousands of dollars over the years on underwater video systems, and after flooding and destroying my Sony/Ikelite HD video camera, I decided to try a GoPro. I have a Hero 2 that I liked a lot, but always wanted an LCD BacPac for it...never got around to buying one, so I picked up a new Hero 4 Silver. Built the mount/handles for out of PVC, and the light is one I found on Amazon...good to 120'. $319 for the camera, $30 for the light, and $5 for the mount. I'll let you know how it works out.
