Subsite® Electronics offers a versatile line of beacons to work with our broad range of HDD tool sizes and Subsite HDD Guidance Systems, including the 750, 752, 8500 and TK Series. These beacons are as durable as they are dependable in providing HDD bore-path data. Rubber end caps, secure HDD tool clocking contacts, and springs on battery fittings provide better protection from shock and vibration and enhance overall performance. And all of our beacons can be repaired, to help save you money.
