The sounding cable set is intended to facilitate Schlumberger and Wenner soundings. The
cables incorporate heavy gauge conductors with excellent insulation to ensure good survey
results. Moreover, there are convenient, short hook-up cables that reduce setup times and
permit you to position the cable drums as desired.
Another important feature of the sounding cable set is easy expandability. If you need to run
longer cables, for deeper penetration, you can purchase additional drums and connect them in
series with your present drums.
