The ComStar Full Duplex Wireless system by Eartec now has double the capacity, going from 8 to up to 16 users. Now larger teams can enjoy simultaneous, hands free communication within an 800 yard range. The All-In-One headsets are completely wireless and there is no delay when transmitting. This is achieved by interlinking ComCenters which are fully portable, operating by rechargeable battery or AC power. The system is dual channel with a “conference” option so that two separate groups can either talk privately or combine their signals.
