Our lightweight and portable (5.75 X 2.25 X 1.0 in) Geophone is a perfect accessory to an existing tracker’s tool kit. Small enough to fit into a shirt pocket, it has exceptional performance with very high gain and low noise operation, along with immunity to power line and radio frequency interference.

Our Products

Shirt pocket sized Geophone amplifier with high sensitivity and excellent noise reduction to eliminate 60 Hz power line and radio noise interference. Comes singly or in a complete kit.

The GeoAmp XT can be purchased as part of a complete kit that comes with a GeoAmp, a geo probe with 50’ cable, a hi quality set of headphones, a 6’ audio cable for vehicle hookup and a hi impact field case.
