Yes, I love it! <a href=" http://www.maxicrop.co.uk/lovegra-online-australia/#picnic ">cost of lovegra</a> Their product is a Wahooo Swim Monitor System. The system requires each swimmer to wear a headband, called a swimband. The band contains two sensors and a sonar transmitter that sends out a signal when it is submerged longer than 20 seconds. The signal triggers warning lights posted along the waterfront begin flashing yellow, and after 30 seconds, the alert turns red and a siren starts going off, alerting lifeguards that someone is in danger.
