Move along the path of the wire swinging the antenna, following the course of the loudest
signal. From the beginning to the end of the cable, the cable location is the path that emits
the loudest signal outside the NULL boundaries (to the immediate left and right side).
Finding Broken Wire – Breaks in wires can be found with the Pro290. The set up of the
unit is the same as when tracing wire. The difference comes in the reception. Whereas the
traced wire continues to emit a signal along the path of the cable, a break will cause the
signal to stop at the point of break. Severe damage will cause the signal to drop to a lower
level but not necessarily end. Minor damage cannot be located with the Pro290 as not
enough signal is dropped to notice a difference in response.
Be sure the cable or wire you are tracking is grounded. THIS IS A MUST. The signal needs
a path to return to the ground stake and without it, you will not get a good locate. Bad
ground is indicated on the transmitter by observing a weak or no light on the LED. In many
cases, a directly buried cable fault will provide this grounding and allow a locate.
Helpful Hints – Increases in signal strength and/or the size of the area it is occurring from
usually indicates some type of anomaly in the cabling. Things that could cause this are
slack loops, nicks, cuts, bad splices, or cut wires. A good condition cable does not
normally change the tone or strength, other than a very gradual loss of reception over
distance or abrupt depth changes, but it is possible. Slack loops (extra wire coiled and
buried) left in the ground at installation are an example of a condition that would cause an
increase of signal and yet have no problem.
Also, ground condition and moisture make a difference in the performance of the Pro290.
Be sure your ground stake is secure, in the dirt and that the transmitter is connected to the
cable you want to track.
In addition, the more conductive the soil, the better. Dry sandy desert soil is not a good
transmitter of signal, and you will experience better results in moist soil. If you are in the
desert, a little water at the ground stake may help.
The best way to really learn the Pro290 is to use it. Set up a test site at your home or office
and get used to how it works. There is no substitute for experience in the art of locating.
Good luck!
