Pool Patrol PA-30 Pool Alarm
The Pool Patrol PA-30 Pool Alarm gets the top nod here because of its versatility. It will work equally well in either an in-ground or an above-ground pool. The alarm is equipped with a remote sensor that sounds both the pool alarm and the remote alarm, which can be located up to 200 feet away. It floats on top of the water, which means installation is a snap, and it reacts to any wave that is created when unauthorized pool use is in progress. It is adjustable for sensitivity, which will inhibit false alarms, and runs on one 9-volt battery.
