Search techniques
Target Verification
After detecting a target, do the following:
1) Walk around the target in a circle.
2) While circling the target, continue sweeping the search coil across the target.
3) Sweep once every 30°or 40°of the circle.
If the tone does not change and the Target-ID value is consistent as you circle the target,
you can be highly confident of the target’s identification.
If the tone or Target-ID changes as you circle the target, you may have multiple targets
or an irregularly shaped object.
If the tone completely disappears at different angles, the target may be trash or low-
value metal.
If you are new to the hobby, dig all targets. With practise in the field, you will soon be
able to correlate audible and visual target feedback with certain types of metal objects.
Search coil movement
When swinging the search coil, be careful to keep it level with the ground about 1/5 inch
from the surface. Never swing the search coil like a pendulum.
