I use this formula the max distance is half the distance of avaliable vis or 50 feet which ever come frist this means. of course you must account for the divers comfort and I mean both divers and I also require all my divers carry a redundant independent air source ( pony) this is a must in diving like a reserve parachute in skydiving never and exception 10 ft of water or 100 ft of water
I guess I will never be able to be your buddy...:depressed:
