The Seal SwimSafe™ Swim Monitor Band is designed to work with the Seal SwimSafe™ Swim Monitor System. The Band is a lightweight, wearable device that will alert parents, lifeguards, and others of any potential danger while having fun at the pool. The Seal SwimSafe™ offers the most advanced swim safety monitoring technology available today. Using our patented RFAO technology, the Band is in constant communication with the Seal SwimSafe™ Hub. If contact is lost either by a swimmer being submerged for too long, removing the Band, or leaving the Hub coverage zone, the Band and Hub alert others of possible danger with a sequence of alarms and flashing lights
