exactly where the valve solenoid is. Use a probe to find the outline
of the valve box before excavating. This will assure that unwanted
damage isn't a result of your locate. Once the valve is located,
verify that it is indeed your target either manually, with the Pro48,
or from the controller.
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 –
Broadcast mode is different from using the
direct 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 has to 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 20 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 (without solenoid) traveling
through this electromagnetic field will pick up at least some of the
tracing signal, making that conductor traceable with the wand.
There is nothing a user needs to do with any controls to use
Broadcast Mode other than the selection of Broadcast mode on
the transmitter and receiver. To do this, place both the
transmitter and receiver in the Broadcast Mode by selecting
"Broadcast" on the selector switch. Place the transmitter on
