I am a commercial diver, after i got married i was a golf ball diver for a while. (dont laugh) and i live at a lake that is popular during the summer with rich people who think they must own a party barge to go fishing. i was thinking about getting a hookah for personal boat maitnance maybe make a quick buck off the locals and the yuppies that dont know how to take care of thier toys or get drunk and throw stuff over the side... there arent many divers in this little lake community so ive had to go in after some things for the city in the past too... problem is the closest place to get tanks filled is about 45 mins away... i was thinking about getting a hookah system but there are so many choices: battery powered, gas, deisel, floating, docked, 1,2,3, person ones... and the list goes on anyone have some experience here that can help me out?
