w/ flashing light
After using 20 unique and internationally patented functions, the creators of the Waterbuoy
are confident that you will be able to enjoy your water fun without
having to worry about valuables falling into the water. So here's how is
works: After your keys, radio, tools etc. fall into the water a trigger
activates gas to be released into a balloon which has buoyancy to lift
1Kg. As soon as the Waterbuoy is submerged in water a flashing high
intensity LED is activated. This makes the Waterbuoy the first flotation
device visible at night.
