Which Diopter?

These days it is pretty hard to choose from all the diopters available – you probably have at least one old school one in your kit bag. ┬áThe Inon UCL 165 and 330 were the first mass produced diopters specifically for underwater use, before those we had to use slide on single element diopters (woodys diopter), or put a higher quality dual element diopter directly on your lens before you got in the water (Nikon 6T).
