pinpointing shallow targets

[Eddie Currents]

This morning I discovered that pinpointing the shallower targets on the T2 can be less accurate than the deeper ones. Sometimes I'd be off by several inches which really complicated recovery. I presume this is due to the DD coil's field pattern.

So I tried some things and came up with a simple method that worked well for me:

When pinpointing a target (if the depth value reading is small) I would pinpoint as usual in one direction and then turn 90 degrees and pinpoint again. This worked well every time on the shallow ones.

On the shallow targets, have you tried turning the coil on edge?

No, I haven't tried that. How is it done exactly?

Just turn the loop sideways to use the edge, and go to pinpoint. It won't work on really deep targets, but can really be a blessing on things that are shallow with a widescan loop.

Why not try ratcheting down the field of view of the coil by double pulling of the pin point switch.

It's explained in your owners manual. I don't remember what page #, and not having a manual handy, can't look it up.

By doubling or tripling the pin point switching, you should be able to narrow the target window to a small area.

Yes, that's a part of my regular pinpointing routine and it works fine for me. But, with shallow targets (to about 2 inches, say) I find that doing a regular pinpoint twice at 90 degrees is just a quicker and easier way of zeroing in.

I didn't mean to say there is anything wrong with the T2's pinpointing ability -- there isn't. I just found this trick to save time in some instances.

OK, I will try that -- thanks.

I just lift the coil farther off the ground sometimes...seems to help.

OK

The pin point feature has changed a bit with the R6 version. It does act a wee bit different than before with the ability to change the pin point signal strength.

I'm with you with the X'ing way of pin point. After many years of using a PI detector, I have just done it as second nature.

Have a nice day.

With shallow targets there is no need to use the pinpoint feature or x'ing, or 90 degree turns.

Since the DD coil gives you a nice straight detection field, stay in Disc mode and just wiggle the field back and forth over the target as you gradually pull the coil back toward you. When you lose the signal, wiggle the coil forward until you pick it up again. It will be right under the front edge of the coil.

If you want to use the pinpoint feature on shallow targets, consider the DD Stab. Pull the trigger and poke the toe of the coil at the target, and to both sides of the target. You can pinpoint to right under the front edge of the toe of the coil.

I probe almost all my coins and I seldom use the pinpoint feature on shallow targets. Within a very short time of practicing these, you will find both of these techniques to be extremely fast and accurate methods of pinpointing shallow targets with DD coils.
