Eartec Evade - Light Industrial, Full Duplex Wireless Intercom with Single Ear Headsets Eartec EVADE's are a new generation of full duplex team intercoms designed for professional crews that require crystal clear, hands free communication. A complete EVADE system allows up to nine users to talk simultaneously within a 400-yard range enhancing coordination, productivity, and safety. These EVADE wireless headsets are engineered with a single ear that can be worn on left or right leaving the one ear free. They feature "All in One" Light Industrial design including deluxe padding along with sleek fully adjustable headband that provide outstanding comfort and rugged durability. To operate the system simply install the lithium polymer batteries (included), turn the headsets "ON" and talk! EVADE headsets utilize Frequency Hopping technology which means they automatically switch channels in order to circumvent interference. They do not require wires, belt packs, or even a base station, instead a specialty "MAIN" headset relays the digital signals of up to eight "Remote" units. All Evade Single also include Eartec's "Auto Mute" mic boom that swivels 270 degrees to be worn on either left or right and cuts off the headset gain when set to the UP position. The headsets are field programmable and expandable to accommodate your growing needs. Battery charger and soft side storage / transport case included.
