The receiver is manufactured using the same digital technology as the RX Micron, and can indicate most of the features signalled by the alarm unit at ranges of up to 200m. Four ultra-bright LED's indicate which rod a run is on and can also differentiate between a forward and drop back movement. Volume control and low battery warning complete this impressive system and the tone setting of each head is mimicked by the RX Reciever. Subject to environmental conditions.
