If you’re an avid boater or like to spend time fishing, you shouldn’t leave home without the Waterbuoy attached to your keys and/or valuables. When aboard, sometimes things go overboard; you may not be able to jump in and get something like a set of keys before it sinks.
The Waterbuoy works exactly like a miniature rescue device. When your keys -- or other objects that have the Waterbuoy attached to them -- fall into the water, an orange flotation device emerges and brings itself back to the surface within seconds. It also has a built-in light that acts as a beacon when it is dark and harder to find.
