Walter:Lots of systems exist, but the best system is a simple roll call.
1. Everyone shuts the hell up and listens to the roll call.
2. Everyone answers for themself only.
3. Person conducting the roll call hears and sees each person as they answer.
4. Roll call is conducted at the dock before the boat goes out.
5. Roll is conducted after every dive.
If those simple rules are followed, no one is ever left behind.
grassyknoll:It would be fairly easy to provide a Wiegand fob on a caribiner to each diver. They would be programmed as Diver 1, Diver 2 etc... Once the boat is under way a rechargeable battery-powered hendheld reader is quickly taken around and each diver presents the card to the reader creating a list of who is or isn't on board.
plot:I had an idea for putting a small transmitter on the boat, then giving the divers a device that will point to the location of the boat. I decided it'd be difficult without using gps (which can get expensive), and moreso, how well gps would actually work under water...
I'm sure the kinks could be worked out, but the cost might get a little out of control for such a simple little device.
