PINPOINTING
PINPOINTING IN MOTION SEARCH MODE
Pinpointing in the search mode will take a little practice but you may find that for most targets, it’s even quicker than the Zero Motion Pinpointing Mode. Simply use the same procedure as in steps 2 through 5 above. The only difference will be that when you stop the coil over the target you will lose the audio signal. You must keep the coil moving at least slightly to determine the location of the strongest signal before you stop it.
1.For very strong signals, you may improve your motion mode pinpointing accuracy by adding one or more of the following steps:
a.Lift the coil until the signal is just 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.
2.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.
When the stem length is properly adjusted, the 1225- X is balanced for sweeping in a tight semicircle. Always overlap your sweeps by at least 50% or you’ll miss a lot of the deeper targets.
