Excellent Wire-Free Harris Mic/Earpiece Solution
I work long shifts in a secure facility, where the Harris radios often have defective hand mics (to say nothing of the hygiene & health issues of sharing and breathing over hand mics). My unit radio only had one radio battery, so I needed to maintain mobile radio comms whilst leaving the radio on charge - when I saw this Bluetooth adaptor I knew it was a Godsend. Powered from the radio - works great.
I have paired my Bluetooth headset with it so that I can be hands-free whilst on the move. The BT finger PTT works in tandem.
When my headset runs out of battery I just plug in the Sheepdog mini mic/earpiece that I also bought from CommGear, carry the radio with me and charge the headset whilst I'm on the move.
I initially bough a full-size speaker-mic from CommGear, which I keep handy as a back-up. Great company. Excellent service.
