SB40 Price: $29.95 - Includes GP-23A Battery.

The Model SB40 Sonic Location Beacon™ is an audible beeping device that may be used to help locate model rockets, model airplanes, payload carrying balloons, and so on. This device creates repeating 2800 Hertz patterned beep tones at a volume of 105 decibels. The device has a mute system that may be used to silence the beacon until takeoff, or until deployment of the parachute. In the silenced mode, the beacon will run for a week on a fresh battery, which means that you need not be concerned about how long the rocket sits on the launch pad. When beeping, the battery life is in excess of 24 hours, so you'll have plenty of time to look for a lost rocket or payload.

The SB40 measures 1.7" wide by 0.7 thick by 2.5 long. Its weight with battery installed is only 1 ounce, and it fits inside a tube with a minimum ID of 1.77 inches. It will operate mounted in any orientation. This device runs on a 12-volt alkaline lighter battery. It can be heard from a distance of over 250 yards.


Additional GP-23A Alkaline Lighter Battery; Price: $2.25.
