Amazon.com: First Alert A100 Aqua Alert Water Actived Safety Band, White/Blue: Home Improvement
'Aqua Alert is a one-size-fits-all electronic “wrist band” device that emits a loud sound when submerged. Designed to fit toddlers to teens, the band has a locking attachment and fits snuggly on the child’s wrist. The face of the band contains electronic alarm components. If a child should fall into any body of water, the water completes a circuit in the Aqua Alert water activated wristband watch and triggers an alarm that sounds at about 110dB – similar to the piercing sound of a smoke detector. Aqua Alert’s sole function is as an alarm alert that assists parents with an audible warning to help them protect their child or children from a drowning or near drowning accident. Aqua Alert is NOT a flotation device; when any child is near water, parental vigilance and supervision is always required.'
