SB1 Price: $19.95 - Includes GP-23A Battery.

The Model SB1 Sonic Location Beacon™ is a small audible beeping device that may be used to help locate model rockets, model airplanes, payload carrying balloons, and so on. This device creates repeating 4000 Hz patterned beep tones (double beeps) at a volume of 90 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 SB1 measures 0.55" wide by 0.60" thick by 2" long. Its weight with battery installed is only 0.42 ounce (12 grams), and it fits inside a tube with a minimum ID of 0.68 inch (17.3 mm), a loose fit in an Estes BT-20 body tube. This device runs on a 12-volt alkaline lighter battery. It will operate mounted in any orientation, and it can be heard from a distance of over 50 yards.
