pin pointing with DD coil

[coach c]

I am sure this topic has been thoroughly discussed. I have been off the forum many months and now getting back into treasure hunting. I have very little luck in pin pointing an object with my AT Pro DD coil. I am never very close on the first dig. I have tried finding the spot and turning 90 degrees to find the intersection. I have tried pulling the detector toward me and determining the place off the nose of the coil. Does anyone have a suggestion? Or if this is old hat, tell me where to find the discussion covering this in the past......Coach C

Have you watched this video?

No. But I will. Thanks. I also just found John Edmonton's post and video from earlier this year. These should help. Hope I haven't waisted anyone's time but if you have discovered a secret to accurate pin pointing, let me in on it......Coach C

The DD runs in a straight line. Watch where that line is then turn 90 deg and get that line and you have the exact center. Works for me.

One other thought on the DD. Coins that are on the surface or just under the grass clippings are often hard to pinpoint because they have such a huge signal. De tuning the detector by moving it close to where you think the coin is and then pressing the pinpoint. You can refine this by doing it more than once.

Throwing a bunch of coins into the grass and going and finding them with the detector is another way to learn pinpointing.

Good luck

In honest reality it takes a little practice to catch on to pin pointing with the DD coil.

I believe throwing a coin down in short grass is one of the best ways to practice.

I pin point both with the front to back side to side method. Waggling the coil over the coin really works great also.

I first do the.. Sid to side, then the front to back and use the square part of the coil frame right in front of the
coil attachment screw to be center of the target. I can hit it like 95 per cent of the time now.

You can also use the front and back edge of the coil to find the target. Going very slowly try and center the
target with the coil in pin point mode. Once that is done slowly move the coil forward in pin point mode until the target
Sound Just starts to disappear from your phones. The target is at the back center edge of your coil. You can now pull the coil toward
You in pin point mode. When the front edge of the coil looses the pin point sound your target will be at the center of the
Front edge of the coil.

Waggling the coil means to center the coil over your target. Move the coil from side to side in about 3 inch motions
Like a golfer may do a driver. The center of you DD coil is very sensitive and when you target is seen by each edge of the center
Strut of the DD coil it will chirp. You will get 2 quick chirps one when the coil senses the target and the other when it leaves one side
of the DD and goes to the other side.

If this hard to visualize draw two capital D's backward with their straight bases next to each other. The two straight
Bases represent the two separate DD coil windings. You chirps in waggling are each coil have sensing the target.

Long explanation but that is how it works.
