300/800 Dual Frequency Digital Antenna

The 300/800 MHz dual-frequency antenna was GSSI's first digital antenna. The combination of two frequencies allows users to locate targets at depths of up to 7m (21ft), ideal for utility, archaeological and environmental surveys. This antenna is compatible with the SIR 4000 control unit and Panasonic G1 controller.
