If you’re going to spend some time on a fishing or boating vacation, the Key Buoy might be just the thing to give you that added peace of mind. Hang your keys on it and if they fall into the water, the buoy will be triggered, sending up an air tube that inflates automatically and rises to the surface within 30 seconds. With its cheerful orange colour, it’ll be readily visible bobbing on the water.

The Key Buoy is strong enough to rescue a weight of 4.2 oz (120 g) and is good for one use only. But that one use lasts for 40 minutes, which is plenty enough for you to get around to rescuing your keys from a watery demise!
