Do not buy this device for scuba diving! It's made of thin, cheap material. It's by no means neutrally buoyant, my hand got tired of holding it while snorkeling. The red filter isn't the right red and all my shots turned out very green (for comparison I used my GoPro, same settings and everything, with a separate red filter and supersuit and the shots turned out beautifully). The macro is weak. To be fair, I believe it could work for this purpose if you ONLY took top/bottom split photos in ultrapure water.
