There may be more than one valve on the cable being traced. You may
wish to continue past the first valve located to determine if other valves
are also located on this wire.
Broadcast Mode –
from using the direct clip-on method of connection that has previously
been discussed. It is not as precise or strong as direct connecting, but
when access to cables is limited or just a quick scan is required, Broadcast
Mode can be very useful.
Broadcast mode is excellent for finding telephone or cable TV lines. It is
less useful with wires attached to solenoids. The principle in use with
Broadcast mode is AC induction. On ordinary wires, that works well. And
it can work for sprinkler wire, but the solenoid sometimes must be
eliminated from the circuit. This can be done by disconnecting the
solenoid and grounding the wire manually. The problem is that the
solenoid acts as a signal dampener with AC inductance. By removing the
solenoid from the circuit, you can find sprinkler wires in broadcast mode.
Deactivated 2-Wire systems do not have this issue and are traceable as
they exist in the ground.
Broadcast mode uses an inductive antenna located in the transmitter case
to broadcast a signal around the case in an approximately 25-foot radius
in all directions. It allows the user to transmit or induce signal from the
transmitter directly into the ground. Any grounded metallic cable or pipe
traveling through this electromagnetic field will pick up at least some of
the tracing signal, making that conductor traceable with the wand.
Place the transmitter on the ground over the cable you wish to trace and
select Broadcast to begin. A vertical position of the case increases the
power induced into the ground. The transmitter is now inducing signal
approximately 20 to 25 feet from it, and energizing any conductors in
that field. You may now trace any conductor that has picked up that signal.
Also note, when the user is within 20 to 25 feet of the transmitter, you
cannot trace a cable because the signal from the case itself will overpower
