I hadn't noticed (and actually wouldn't have understood even if I had noticed...)
Checking out the Speardiver now.
Thx
Display MoreFrom that site:
"Its penetrating light beam can reach a distance of up to 622 feet, it is waterproof and it can be submerged into water up to a distance of 500 feet, more than the average dive torch." :laughing:
I doubt it penetrates through over 600ft of water. The sun barely penetrates the euphotic zone which goes to around 650ft from the surface.
I have seen and used the Speardiver torch and it works good for checking holes on the reef.
