A-Kabel ArborCOM headsets allow hands-free, full duplex encrypted communication between two matching headsets up to 200 metres apart. ArborCOM headsets work in pairs (2 Headsets required). Communicating in high noise areas can be difficult, sometimes impossible, especially when chainsaws, chippers and heavy machinery are working flat out. Noise and poor communications can compromise safety and significantly reduce productivity. ArborCOM headsets make communication between climber and groundie nice and smooth, no need for any hand signals, shouting and having to stop work! No buttons to push and hold in when talking, merely turn the headsets to ON and carry on working. The FULL DUPLEX feature allows both operators to talk to each other at the same time, just like talking on the phone.
