Protect your youngest family members with a pool alarm system that warns you immediately when children fall into your swimming pool. Simply lock a Safety Turtle Wristband (sold separately) around your child's wrist, and it will send a signal to the AC-powered Safety Turtle Base Station inside your home if your child falls in. The Safety Turtle Base Station emits a piercing alarm to alert you immediately to the danger. No Permanent Hardware Installation Required Unlike expensive hard-wired pool alarm systems, the Safety Turtle pool safety system doesn't require hardware in or around the pool. Plus, the wristbands and base station are completely transportable. Take the safety alarm system with you to friends' or relatives' homes. You can even take it to the lake or camping by a river: A rechargeable battery pack is available to power the base station when no AC power is available. Color-Coded System Prevent Interference with Neighbor's Systems The Safety Turtle system uses a color-coded system designed to minimize false alarms or other problems due to neighboring systems. Each colored wristband operates on a different frequency; make sure that all wristbands communicating with your Safety Turtle base are the same color. The Safety Turtle Wristband is available in green, blue, purple, red, and yellow.
