When I was diving with Virginia Taylor for golf balls in Florida near Orlando, it was 1970. We had not thought about either octopus regulators, or bailout bottles. But, I survived.I'm not a golf ball diver......although I do consistently contribute from the topside to the thousands of balls found in a water hazard. Whether on hooka or scuba....I'm thinking that a back mount bailout bottle with 2nd on a neckless is a must for this type of activity.
I'm also thinking that for these shallow depths, that once I had a full "load", I'd attach a lift bag and put it on the surface......then just pull it......or them.... to shore once done with my dives.
