We are currently refining a new way of moving through the water at faster speeds and longer distances using natural forces. The Dive Glider does this very well and without batteries, propellers, or noise, and with little or no maintenance. Like surfing, sailing, or skiing the pilot manipulates natural forces to propel himself through the water and did I mention it's FAST! FUN! and you look very COOL doing it. We are especially interested in knowing how you think it may be used in the real world as we don't know what all applications it could be suited for. For more info go to www.goldenrockdive.com DiveGlide page.
 
Will have sinking rate adjustmens and warnings? i design control systems and if this were my product, i even wil not try without a safety system to control the sinking depth, the resurface rutine (deco stops ) and left the air controll of the glider separated from the diver main system
this will be a good tank carrier, buoy or underwater truck. just my 2 cents
 
Very interesting device. I see it potentially as a submersible dive float that can also be used for propulsion. Issues with neutral buoyancy while diving off the bottom and during safety stops. The video shows the diver ascending faster than his exhaled bubbles. You will be competing with the lower end dpv’s so should keep the price below $500.

Looks like a freedive to me. With air inhaled at the surface, ascent rate isn't an issue.

From the video I have no idea how this thing works - where does the propulsion come from?
 
It's a nice idea, and I'm sure it'll be fun to use.
However...
At the projected price point, $3500. it's about 5 times more expensive than it's existing DPV rivals.
Good luck, I think you'll need it.

Looking at it, it's naturally negatively buoyant with a lifting surface wing and a ballast chamber much like a submarine.
adjusting the buoyancy characteristics causes flow over the hydrofoil sections giving forward propulsion.
 
At about 2:22 into the video the camera mounted on the glider is turned to show the diver. He is breathing from a second stage that appears to be connected to an air supply in the glider (AGE alert!). This device would certainly be helpful for the free diver since it would speed up his descent and ascent without effort. This device would be quite easy for the DIYer to build in a home workshop. But if priced around $500 it would likely enjoy modest sales.
