Pool Safety Immersion Alarm – Underwater Motion Sensor with Poolside Siren – For Above-Ground Pools up to 24’ Round or 16’ x 32’ Oval

Great price, works fantastic.

Really need a lot of waves for it to sense anyone swimming. Definitely wouldn’t detect toddler if doesn’t detect and adult or teenager.

according to our state we need a alarm for our above ground pool. Easy to install, when you hit the side of the pool it emits a high pitched siren sound. its easy to turn off and its easy to reset.

If you're pool water is too high the alarm will not work. Additionally, play close attention and use common sense on the drill template. It says to drill two 3/8" pilot holes. This should read drill two 3/32" pilot holes. No pun intended but big difference in the two.

I had to make many adjustments because it did not work for the pool I have coleman 16×10 Above ground It did not bring parts to assemble in the pool.

This does the job for our adove ground pool

We have a steel above ground pool. We had to remove one of the top plates to get the unit to sit in the water. It is so bulky at the top it has bent the top plate of the pool in order to get it to stay on. The sensor is junk and does not move properly. It takes a whirlpool to get the sensor to activate the alarm. Not the best safety device...
