I'm in the process of building a 'non-tech' canister dive light and one of the main challenges was finding an appropriate waterproof canister without spending an arm and a leg. I finally decided on the otterbox, in this case Otterbox 8000 series. The box comes with a neoprene gasket rated to ~100ft. Since I'm not a technical diver, I only wanted to extend the depth rating to ~200ft.
So, to beef up the gasket I laid down a layer of RTV silicone gasket on top of neoprene seal and made it flush with the edge of the lid (no excess rtv bulging from the gasket channel). Let it set for 24 hrs.
I recently tested the canister down to 175ft in 38F water. No leaks.
I realize this is a far-cry from exhaustive pressure testing, but at least it shows that it's possible to easily reinforce the otterbox gasket to withstand greater depths. By the way, the otterbox is being touted as 'crush-proof', so the only weak point is the gasket.
I'm creating this post for those that may be interested in building a low cost, non-technical canister dive light.
The next step will be to run a cable from the canister to the light head, spider light with seoul SSC P7 LED.
I'm willing to share all of the details and pictures with anyone interested in this.
