Protect your young family members with a pool alarm system that warns you when children fall into your swimming pool. Simply lock the Safety Turtle Wristband around your child's wrist, and it will send a signal to an AC-powered base station (sold separately) inside your home if your child falls in. The base station will emit 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 battery pack is available to power the base station when no AC power is available. Minimizes False Alarms Caused by Normal Kids' Play The Safety Turtle Wristband features a bright-colored turtle and locks securely onto your child's wrist with an included key, ensuring that it doesn't get removed or lost. Designed to withstand play, the rugged Safety Turtle Wristband must be fully immersed in water before activating, so you'll never get a false alarm due to rain or spray from hoses or lawn sprinklers. Color Coded to 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 also available in blue, purple, red, and yellow.
