You have just identied the two“Crossing Nulls”,and the line between them indicates the lay of the line
is parallel to the axis of the transmitter,and we will assume for the moment that line is running straight
through that point,along the line of the Crossing Nulls.If it takes a bend,you’ll still have a good idea of
where to look for it.
Two things to always check before you sta a locate,and again if you have trouble:
Make sure the batteries in both your transmitter and receiver are working. If in any doubt, throw them
out! A weak transmitter batte 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.
The signal from my transmitter suddenly quit.I was following it ne,then it disappeared.
Aside from checking batteries, 512Hz 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 pa of locating.
If the signal drop-o is at a paicular spot, and the signal returns when you move a little fuher away
than it is a null.
