Dont Get Caught Out losing your keys overboard.
Here is what Davis Instruments Say :
The ultimate key fob for boaters and lakeside loungers! When keys fall in the water, Key Buoy self-inflating key ring opens up, releasing an air tube which inflates automatically.
We aren't the only ones who think Key Buoy is one of the most practical and clever products we offer. In August, 2006, it was awarded the Innovation Award at MAATS.
"The Key Buoy from Davis Instruments was the clear winner in the Personal Gear/Soft Goods category, according to the judges. 'We are all familiar with the sinking sensation we get when we drop our keys into the water,' said Roger Marshall, Innovation Awards chair. 'The Key Buoy is a PFD for keys. Drop your keys over the side, and they sink. But wait a few minutes - a special balloon inflates, and your keys come bobbing back to the surface.'"
The 14" (47 cm) inflated tube extends above the water, allowing you to reach over and pick them up. Key Buoy rises to the surface in as fast as 60 seconds. May take longer in deeper water with maximum weight attached. Strong enough for items weighing up to 2.8 ounces (80 grams) such as keys, small tools, deck plate keys. Suitable for single use only, so keep a spare on hand!
