• During 1999 and early 2000, the U.S. Consumer Product Safety Commission conducted a review of commercially available swimming pool alarm systems. (For the PDF: “An Evaluation of Swimming Pool Alarms” ). The surface wave sensors tested were priced between $149 to $200, and the subsurface sensors were priced between $190 and $250. The wristband alarm system cost $179 for one wristband and the remote alarm. (It is estimated that about 24,000 alarms are sold annually and that sales have doubled since 1994.) Here are the conclusions of the review. Test results showed that the subsurface pool alarms generally performed better. They were more consistent in alarming and less likely to false alarm than the surface alarms. When a test object, intended to simulate the weight of a small child, was pushed into the pool, the subsurface sensors detected it most reliably. The subsurface alarms can also be used in conjunction with solar covers, whereas the surface alarms cannot. One surface alarm per
