Made of high quality materials and reliable construction methods, the RFA operates on a 9-volt battery (included) to sound the 85 decibel horn when the end of the sensor arm contacts water.

Comes equipped with a low battery warning and a power indicating LED.

Flexible sensor arm can bend and reach into small and awkward spaces. It can also hold any shape and be self-supporting.

Includes a bracket and screws for easy installation. It can be used portably or in a fixed position.

Manufactured with heavy guage ABS plastic, the components are screwed together (not snapped together).
