Ram's 3-Way Simple Siren is a compact but loud system which offers a
choice of three distinct siren sounds for cars, planes, and boats. Modes can
even be changed when underway. This system comes completely wired with a 2-1/4"
speaker. Some modelers find this to be the loudest practical plane-finding
device. The system weighs 3 ounces and requires a 9V battery.
Instructions are included.
