Some very interesting concepts!
What camera are You using? Any UWflash as well, or are You using a flaslight?


I`m using a g10 canon with canon housing.
Most of the shots are iluminated by an independent dive torch that I hold with my hand on the side (MB SUB - BASE. It is a 20W halogen HLX), so I can light only the part that interest me, but many times I mess the shot be cause I move a bit or I need both hands to change some of the settings in the camera.

I suppose it depends on the housing and the o-ring.

In most of the dive centers I have worked, the rental point & shot cameras are permanently closed with the main o-ring in place. Lucky if somebody cleans and lubs them once every two months and they never leak.
But with bigger housings and/or different o-rings I found that if I don't clean the main o-ring regularly (almost every time I use it) they accumulate more sand and dust and after a time start to leak.
The other problem is when you keep the main o-ring in place and you close the housing it loose slightly the original round shape and doesn't seal so well. Also the dirt that it may have can damage it and make small holes or cuts if you keep it under pressure.
Since then I store in a zipbag the main o-ring and clean and lub it before each use with no problem. For the dive center ones they still are fine as they were.
