Don,
I've actually done one of these type of tournaments before. They are a lot of fun and very effective safety wise because the diver waiting his turn to dive is right at the diver's side who comes up with the gun so that a quick exchange can take place and the next diver can dive. If it works right, 2 divers can dive all day with almost zero surface time (except when a fish is shot of course) because as one diver dives the other one recovers/breaths up and then goes almost immediately upon return to the surface by the diver who was just down. It can be done either where the non-diving member carries the float and float line while the diving partner uses a reel gun and then each get swapped or the good old standard system can be used where the gun is hooked to a float and float line and the entire unit gets swapped after each dive.
