Before you begin, you must choose a SONDE that will match the same frequency as the RECEIVER. You will
need a SONDE with a frequency of 815 Hz or 8 kHz to use with the 8879 Receiver.
The key to S
ONDE locating success is practice and patience. Before going out on your first locate, it is a
good idea to take your RECEIVER and SONDE out and try locating the SONDE and calculating the depth.
Locating a Sonde Using the 8879 Series
You will also need to attach a push rod to the S
ONDE. This can be accomplished by using the coupling on
the end of the SONDE. We recommend using a spring coupling to allow the SONDE to move easier. Or, if you
are needing to attach the SONDE to a sewer snake or an auger, it is recommended you use duct tape and
apply as the shown in the figure below. If taping the SONDE on a metal pushing device, it is recommended
to place the battery side of the S
ONDE closest to the device. This will allow for the best performance. Wrap
the snake for approximately 1 foot (30.5 cm) in the location where the SONDE is going to be attached. Also
attaching the S
ONDE 18 inches (46 cm) behind the cutting head is recommended. First, wrap the SONDE in
the duct tape and then attach the SONDE to the snake using the duct tape.
