My first attempt at a home made underwater housing for my Super 8 movie camera. Circa last century. It was ugly but it worked. Bonus feature #1: waterproof on/off switch - very handy when you are shooting movie film that costs $600 per hour (before editing out all the dud bits). Bonus feature #2: it was so big and bouyant I could duckdive and it would drag me to the surface like a short board. Best comment: "Are you shooting commercially?" from a lady surfer at Tea Tree - Noosa.
