We're in the market for a good but not exorbatantly priced comms set to fit our AGA Mk II masks. It'll be used with surface supply so wireless is not a requirement. With so much input to the sbject of full face masks recently, I guess someone out there has an opinion. A set callled Diverphone (available from Australia for about $Aus5000.00) is being considered. Second up, is there a commercial, diver recall system available? We use Navy thunderflashes, small, harmless, explosive devices which provide a good thump and have sufficient Magnesium in them to give a good flash in gloomy conditions. Divers respond well to them. I wonder how dive boat operators recall 20 - 30 divers in a hurry. I got some idea that an underwater siren system existed. Any comments appreciated.
