Also, the review indicated that maybe they have been underwater and didn't instantly flood, so maybe it will last at lease a few dives -) These are one of the many Chinese units that are all over the market. It uses a standard 18650 battery and via ebay listing appeared to have some room where the reflector is. I chose a cheap metal light for the "host" that I found on eBay. The other is a simple double A plastic pen pointer at Leisure Pro (and direct from China.) It looked like it might be an easy unit to convert but eh. One is fairly expensive at $100, and it's unknown if it can be turned up or converted to run other modules. I found two existing units on the market. As I prepare to head on a dive trip with some friends from the laser show system community I'm going to (hopefully) convert a cheap underwater flashlight into a green pointer.
