...taking unnecessary risk with your LIFE! I would never dive with cheap equipment. I want to live a long time and watch my children and grow up. Save your money and buy a quality unit.
Ten feet? nah. I've gone down many times saying "I'm stayin' shallow today," only to get engrossed and look at my gage and be at 25 or 30 feet! When the good stuff is deeper, you'll want to go there.
Once I was diving in cutoffs at 27 feet, right on the thermocline of a freshwater Corps lake here in Arkansas. I looked down (about 10 foot vis) and saw the distinctive glint of gold in the form of a healthy lookin' 18:" chain. I was diving below a bunch of cliffs where the college kids get drunked up and grab-azz around jumping/falling in the water from 20 feet or so. So.. I took off, and didn't make it five feet and got hit by a wall of the most FRIGID water. I went back up to the thermocline and at neutral buoyancy, just hovered there and shivered until I warmed up. Mate, I did that THREE more times before finally just biting the bullet and getting the treasure.
Man I was dyin! I put it in my goodie bag. and kept up the hunt--in warmer water, of course. When I got to the surface, upon viewing my treasure, I found that the chain was FAKE! I was one pizzed off diver.
The moral of the story is: if the loot is deeper you will want to go deeper within reason. So just save a little more and buy a good 280 Brownie gas unit or something equivilent. Keene makes a 12V unit that will support one diver to GOOD depths. They say it will support two divers but most do not believe it is feasible. On a good Group 24 battery, you will be good for 2-3 hours. They are about 1100 bucks for the hookah alone. Once you buy the hoses and the regulator etc, etc, etc. you are looking at $1700.00
For $1,700.00 I can buy a good used Brownie on Ebay if I look long enough. Dive SAFE and don't take chances. Your family will appreciate you thinking of them and spending the extra cash to be a safe diver. If you're not certified, please get the basic course...about $150 at your local dive store. In diving, it's not what you know that's dangerous, but what you DONT know that will kill you dead.
Sorry for sounding a bit preachy, but some folks have the idea the hookah is somehow not so risky as scuba. It just is not true. Whenever you subject yourself to a hostile environment, you must do all you can to be a safe as possible.
Now...go get you a good hookah and get with the program. You're gonna have a blast.
