I lost my GoPro Wide Angle Camera in it's housing around the Point Vicente lighthouse about 100 meters off of shore the kelpbeds in Palos Verdes...
The memory card has a couple pics of a black coonhound dog, a sea anemone, and someone spearfishing. There is a headlamp style head strap conncected to the housing.
