It has a very small footprint so it is well suited to sites that are difficult to access. The Geoprobe 7720DT is the ideal machine for fast environmental sampling. The GH62 Hammer was designed specifically for soil probing applications and hits at over 1,900 blows per minute, delivering forces greater than 80,000 pounds per blow to the top of the probe rod:
