(*) Wrist bands sense the wrist band but do not track the child. Thus children merely standing with hands in the water for several seconds would generate many false alarms. Moreover, if the band simply falls into the water or worn while taking a bath, the alarm would go off.

(**) Each detection systems may generate some false alarms every once in a while. CORAL MANTA 3000 comes with a lot of “knowledge” out of the box, but each pool is different thus it may generate false alarms every once in a while. But, it continues to “learn” in its new environment and thus the number of false alarms is gradually decreased

(***) Some pool alarms have a home alarm and some do not. Some pool alarms have smart phone app that controls or monitor them, but most do not

(iv) Wrist bands are designed for toddlers. But, 45% of all drownings are not kids. So unless you plan to demand your 16 year old teenager or 78 year old grandfather to wear a wrist band each time they go swimming, then this solution is irrelevant for many group ages. Beyond that, it may not fit infants ages 18 months or less

(+) Fences, covers, pool alarms and wrist bands require you to remember to actually perform some action before or after using the pool: open/close the gate or cover, activate / deactivate the pool alarm, wear / take off the wrist bands. CORAL MANTA on the other hand works 24/7 – It does not rely on any humane behavior in order to work and detect drownings
