The Rocket Beeper 2 (RB02) is an acoustic locator designed for use with model rockets. The RB02 has several advantages over other acoustic rocket finders. It has a DC-to-DC converter that boosts the nominal 3.7 volts from a single cell LiPo battery to 12 volts so the beeper will always operate at its optimum voltage and produce the loudest tone. The RB02 has the same dimensions as the RB01 and uses the same batteries. Unlike the analog RB01, the RB02 is controlled by a microprocessor. This allows it to conserve battery capacity and prevent unrecoverable discharge of the battery. For complete details on the RB02, and the optional battery charger module, see the RB02 User's Manual on the Data & Documentation page.
