Geoprobe« 8140 Sonic

After many years of development, the Geoprobe« GV4 Rotary Sonic Head (with Patents Pending) is finally released. Way more than mini sonic!

The primary benefits of SONIC technology are very rapid drilling rates combined with reduced volumes of waste. The Geoprobe« SONIC uses an oscillator with frequency of vibration between 0-150 Hz and maximum rotary torque of 3,500 ft-lbs. Vibration of the drill bit or core barrel can be varied to allow optimum penetration of subsurface materials. A dual string assembly allows advancement of casing with the inner sampler used to collect samples. Small amounts of air and water can be used to remove the material between the inner and outer casing.
