The Geoprobe 6620DT is quite simply the most powerful and versatile machine manufactured today. This unit can probe deeper and faster than any other unit, has the power to penetrate to depths >100', and can switch from probing to hollow stem augers in minutes. The EFS team has named our 6620 "The Big Dawg", and you will know why after your first project.
The Big Dawg, features the GH60 hammer which provide you the needed power to sample in difficult situations. If subsurface soil conditions stop the 5400 hammer yet we are not in consolidated conditions, the 6620 hammer will often be successful at collecting the sample. The Big Dawg has meet it match yet not very often.
