Agent Fox makes the ultimate in outdoor surveillance equipment, the Clark Coat developed for the SOE by Plessey, her own. A Gemstone Capacitor powered two-way receiver rides in a custom pocket in the lower back of her fur coat. A throat microphone is hidden in the (upturned) collar which also houses the jack plug connector to a set of earphones concealed in the fur-lined earflaps of her aviator hat. With a sophisticated aerial system sewn into the coat lining coupled to the considerable power boost available from the Gemstone Capacitor then communication in an urban setting is now possible up to ranges of 500 yards for almost indefinite periods of prolonged use in even extreme cold weather conditions.
