I don’t have a pool and I don’t have kids, but if I did, I might give strong consideration to installing SonarGuard. This just HAS to be one of the coolest technologies available for families looking to make their pool a safer place. SonarGuard basically casts an invisible “sonar net” just below the surface of the pool water. Any disturbance to the “net” (be it a falling baby or a Russian submarine) results in the sounding of an alarm. Apparently the system is pretty smart—disturbances caused by wind, rain, and small toys are filtered out by SonarGuard, and a system deactivated for maintenance or pool use will automatically turn back on, ensuring 24/7 monitoring. A price tag of aroun $5,000 might seem a bit hefty, but no real price can be put on pool safety.
