The Hunt
62
X-TERRA Settings
After setting the Noise Cancel Channel, Volume level, Sensitivity, Ground
Balance and making sure I’m set up in the proper Discrimination Pattern
and with the correct number of tones, I’m good to go.
Sweeping the Coil
As I walk along, I’m careful to overlap my swaths. On Double-D coils I like
to overlap by at least 1/3. On Concentric coils, I try to overlap by 1/2. My
swath width depends on the circumstances. If I am hunting between
rows in a eld of corn, I’m limited to the 30-inch row width. If I am in open
territory, I have a slightly wider sweep. Yours will depend on your height
and arm length. Just make sure you don’t get your feet going faster than
your arm. In other words, overlap those swaths! And don’t be in such a
hurry to work an area that you take too wide of swaths. Doing so can
cause you to raise the lip of the coil up as you switch directions, causing
false signals and missed targets. You’re better o making narrower
swaths, and taking more passes.
The sweep speed I have depends on the number of targets I am getting
in each sweep. As one who hunts in zero discrimination (or All Metal)
with multiple tones, I know what is under the coil at any given time. If you
choose to hunt in a Discrimination Pattern, with some notches rejected,
don’t be misled into thinking there is nothing in the ground just because
your detector isn’t beeping. Those rejected targets also have to be
processed. And the blanking eect they produce is important too.
