Ok when we all first started diving way back when we all had like 20 minutes at 60 feet and many of us had tanks that were almost looked like a coke bottle full of air at 120 feet when we finished the dive LOL. My question is since veteran divers are all too aware of newer divers having a high air consumption rate. How would you handle another veteran offering to take a newer diver to 100 feet and he has less then 10 logged dives? What if when you pointed out the potential hazards and the veteran insist it will be ok and the new diver cant be talked down???
