Pinpointing takes practice. The more time you spend with your

1280-X, the faster and more accurate you’ll become.

1. Once a buried target is indicated by the tell-tale

“Beep” of the 1280-X, continue moving the search

coil from side-to-side across the target in a narrower

and narrower search pattern.

2. When you have narrowed your search pattern

as much as you can and still hear the target, stop

the search coil.

3. Now, move the coil slowly forward and then straight

back towards you a couple of times. Stop the coil over

the area where you get the loudest response.

4. Move the coil slowly left to right to left one more

time, zeroing in on the loudest target response.

5. Stop the coil over the area of loudest response

and rest it on the ground.

6. Your target should be directly below the center

of the search coil.

7. For very strong signals, you may improve your

pinpointing accuracy by adding one or more of

the following steps.

a. Lift the coil until the signal is barely heard.

b. Reduce the sensitivity level.

c. Increase the discrimination level.

d. Rest the coil on the ground and move it back

and forth very slowly.

8. For very weak signals try the following:

a. Move the coil closer to the ground.

b. Increase the sensitivity level.

c. Decrease the discrimination level.

d. Speed up the sweep rate slightly.
