The RRC3 Classic Altimeter is a barometric dual-deploy altimeter, with the features of high-end units, at the cost of those with a more modest feature set. In addition to basic dual-deploy capability, the RRC3 Classic is a multi-flight recording unit, allowing you to fly all day, without the need to stop and download data in between flights. The RRC3 Classic also provides a third, highly flexible and programmable 'Auxiliary' output which can provide staging, airstarts, backup events, and a host of other applications. The RRC3 Classic can also support real-time data streaming capabilities in flight for telemetry or for interface with other custom control systems. Despite this unrivaled suite of intrinsic capabilities and expandability, the RRC3 Classic still maintains its simple "buy it and fly it" operations.
