The Waterbuoy is a must for anyone that spends time around water. If you're into boating, fishing or just about anything else that involves water then the Waterbuoy is for you. For a small price you can save the aggrevation of dropping your keys, phone or gadgets into the water. The unique patented trigger mechanism of the waterbuoy is designed to activate the device seconds after submersion in normal temperatures. This means your valuable won't drift or sink too far before they resurface. Underwater currents can carry things a long way from where you dropped them in a short time, and the Waterbuoy aims to minimise the problems this can cause. The waterbuoy is also designed to minimise the chance of accidental activation. You don't want it going off if you get a bit of rain on it. During our exhaustive trials, we splash tested waterbuoy continually over 1 month. We then dropped it in a tank of water and it worked perfectly. Waterbuoy is the World's strongest miniature floatation device. Small as it is, the waterbuoy is very strong and will lift items up to 1kg of dry weight, and that's strong! That's why the waterbuoy can be used to protect so many of your valuable items, from keys, to cameras, to fishing tackle, the list of potential applications is endless. In addition, if your valuable is heavier than 1kg - attach two or more waterbuoys to it, they're small enough.
