Replacement Part List

Troubleshooting
Two things to always check before you start a locate, and again if you
have trouble:

Make sure the batteries in both your transmitter and receiver are fresh. If
any doubt, throw them out! A weak transmitter battery reduces its range,
weak batteries in a receiver can make it act brain-damaged, as well as
reducing the range.

Always test your transmitter and receiver above ground, for operation
and range, before sending the transmitter down the line. Every time.
The signal from my transmitter suddenly quit. I was following it fine,
then it disappeared.
Aside from checking batteries, 512 Hz equipment will penetrate cast iron, but
not steel, ductile iron or other metal.
A sudden loss of signal may also mean you have encountered a null, which is
a normal part of locating. If the signal drop-off is at a particular spot,and the
signal returns when you move a litter ways away, then it is a null.
My transmitter and receiver seem to work, but I can’t get further than
about 3 feet away before the signal dies.

receiver. It won’t look broken, but even a hairline crack in the ferrite core
inside the antenna tube can destroy its sensitivity. It’s easy for us to fix, but
you have to send it in. A work to the wise: never use the antenna rod for
prying or digging or anything but locating. A hard case is a good investment
for preventing antenna damage.
My system doesn’t seem to be working, but I don’t know how to tell if the
