Fumbling with buttons on a communication device can be a distraction for a crew in an emergency situation. Eartec's hands-free, no-buttons Simultalk 24G wireless radio is designed with these people in mind. Using two frequencies, the radios send and receive signals simultaneously, so users can speak to each other freely, as they would on a telephone. No base station is needed. Each 10-ounce radio is powered by a rechargeable battery, and has a range of a quarter mile. The price includes four radio units, four midweight headsets, batteries and battery charger.
