Waterbuoy. Interesting little keychain product contains a self-inflating balloon which pops open and floats your chattels gently to the surface if you suffer a sudden immersion situation in, say, the nearest ocean or lake. It’s a one time use product only, but since it can support up to a kilogram for over 24 hours, and has a high intensity LED beacon to make location easier, it could be a majorly sensible investment for sailors and landlubbers alike. £14.95.
This clever little device contains a high-strength rubber balloon that can lift up to 1Kg and automatically inflates within seconds of hitting the water, causing the whole shebang to rise gently to the surface. And thanks to a high-intensity LED beacon that’s visible from over 250m at night, you can spot it bobbing about and retrieve your keys/valuables with ease.
