I have a question.... how do you keep your line from tangling with the other diver's line? May be a silly question but I have visions of tangled fishing line or dancing around the maypole!
No, it's a good question, bowlofpetunias. You have to watch out for the line, swim out parallel to each other. Let's say I'm on the left, then when the buddy pair turns, I'm now on the right so the lines don't cross. There is a signal for "I'm fouled, can free myself" and "I'm fouled, send safety diver to free me".
As for the fisherman, I think he was just looking out for a good catch. Mind you, he had to auger another hole to continue fishing, but we were there setting up for the dive before he came along
