Remember those old diving suits with the big metal helmets and the weighted shoes that let you walk across the ocean floor? The divers carried no tanks, relying instead on a partner pumping air down a hose from the surface. If the guy up top decided to take a smoke break, or just nodded off, the poor diver would suffocate.
So forget that lazy, good-for-nothing smoker on the surface. This is 2011 after all. Replace his sorry ass with the PowerSnorkel, a "Power Snorkel Hookah."
The hookah consists of a buoy with a pump and compressor. It sends air down a tube to the diver(s) below. One diver can drop to 12 meters (40 feet), two can go to 6 meters (20 feet). In the latter case, each diver gets their own 6-meter tube which attaches to a y-divider.
A flag on top lets the pump and tank be easily seen and found, the battery will run for about an hour, and the kit includes a pair of regulators and dive harnesses.
It looks like a lot of fun. It's no replacement for Scuba gear, of course. It's more like a power-up for normal snorkelers. For recreational gear, its a little pricy -- $2,500 -- but then again, you are trusting your life to it, and it certainly costs less than keeping an unreliable, ne'er-do-well assistant on your team.
