detection field of the search coil

[23fly]

where is this exact field for Pinpointing located at the search coil.It should not be in the center of the coil?

It is in the center of the coil. This is not typical for a DD coil but that is how it works on the T2.

Just move the coil until you get the strongest signal volumn (and most shallow depth reading) then there is a little dot in the center of the coil (at least on mine) it should be directly beneath that.

When I got mine I assumed it was like the other DD coil machines I had and tried to pinpoint the same way. It didn't work very well.

On the other detectors, most likely Minelab, going into the all metal mode to pinpoint does not put the detector in a no motion mode. Triggering on the pinpoint mode on the T-2 puts it in a true non motion all metal mode, with depth ID. This is why you can get the target to center in the loop.

It's just to hard to do this with a detector that does not allow a non motion mode in pinpoint. With a motion mode pinpoint DD, one needs to do a little wiggle of the loop, and slide the loop forward or backward until the target drops off at the front end or back end of the center line of the loop. Right at the drop off point is the target.

Pinpointing With the Trigger Switch when you turn the T2 on, the ground cancellation setting is preset to give a positive response on nearly all soils. This means that if you are pulling the pinpoint trigger, the
audio tone will get louder as you lower the searchcoil to the ground. But you do not want to hear the ground; you just want to hear the target. So always Ground Cancel first.
After you have discovered a buried metal target using the ALL METAL or DISCRIMINATION Modes, use the trigger switch to pinpoint its exact location.
If you position the searchcoil just barely off the ground, and to the side of the target. Then pull
the trigger, and raise the searchcoil about 2 inches. Lifting the searchcoil away from the ground makes the ground signal go negative, so the machine is silent. Now move the searchcoil slowly across the target, and you can locate it by the sound. The target is directly where the sound is loudest.
