50Hz or 60Hz electrical current. Once the Pro900 wand is on, simply
search an area until you hear a buzzing sound. There is no beeping
signal as the transmitter is not used. Follow the buzzing sound in either
null or peak mode, both will work, to track the cable.
DO NOT RELY
ON THE 50/60 Hz PASSIVE MODE AS THE SOLE METHOD OF
LOCATING POWER LINES
. Passive mode may not detect power
cabling if there is no live electrical current present in the cable at the
time.
How to determine depth -
Find the null over the wire path and mark
it. Then place the tip of the receiver on the ground at the mark. Without
lifting the receiver tip from the ground, lower the top of the receiver to
approximately a 45 degree angle and slowly walk the receiver away
from the wire path until you re-acquire the null. The distance between
the wire path and the newly established null is the approximate depth of
the target. This is the Equilateral Triangle method.
Determining target accuracy -
This is a very easy to perform
method of determining target accuracy. Place the tip of the receiver on
the ground directly over your suspected target location, switch from null
to peak by pressing the mode selection pad. The peak and null
responses will agree if the locate is accurate. If the peak and null are off
by more than a few inches the location is not accurate. Toggling
between the null and peak modes often when locating the wire path will
assure you of accuracy and help build your confidence.
