Pinpointing w/ ATP

[dflan83]

Hey guys,
I took my at pro (upgraded ver) out with the stock 8.5 X 11 DD coil out yesterday to a field to find some relics. The hunting conditions were not the best, the ground balanced at 90 and some areas in the field were very trashy areas. Since I'm new to the at pro and a DD coil in general I need some advice on the target recovery specifically pinpointing.

I read the AT pro manual and tried the pinpointing technique but it always seems I'm off target and end up digging a hole at least as large in diameter as the coil to recover a target. Is there a way to be more precise with my pinpointing technique? I try to pinpoint with the center of the coil, maybe I should try to pinpoint with the front of the coil instead.

Another possible option might be to purchase a concentric coil.

anyway any thoughts suggestions?

I just use the wiggle method and then if I am unsure, I check it with the pinpoint. Works for me.

I found the same thing with my AT and called Garrett. They told me to pinpoint the target as usual then pull the coil back until the sound disappears. The target will be at tip of the coil. Test it on a coin placed on the ground. My holes are a lot smaller.

You'll find the 6 x 9 coil pinpoints just like the 8 1/2 x 11. Using a wiggle or whip method, let's you pinpoint right in the notch. Be sure to pinpoint twice, 90

Pinpointing with the coil off the ground will help compensate a drift from accuracy due to a coin laying on an angle in the ground.

After using a concentric coil on my other machine for 10 years, I was intimidated by the pinpointing of the DD coil. I honestly figure out where the center point of the signal is, rotate 90 degrees and do the same. I then hold down pinpoint and listen to the highest pitch in that general area and usually i'm dead on. I know I spend a bit more time pinpointing, but I hate being off on pinpointing, especially when usually my targets are 8+" deep or possibly scratching a nice coin. Just my opinion

thanks for the replies everyone. I also came from using a concentric coil on other detectors so I'm more familiar with that technology. I'm not yet ready to give up on the DD coil though and I will keep trying to get an accurate pinpoint

The 90 degree method works well for me.

It took me a while to master pinpointing with the 8.5x11DD. Now, I can't remember why it was so hard!

The only way I pinpoint now is following the method described above: Pinpoint then pull the coil back until the sound disappears then I move the coil forward very slowly. When I begin to regain the sound, the target will be at the tip of the coil. Never fails.

I hardly ever need to pinpoint with the 5x8DD

I rarely miss with the 5x8 - my favorite thing about it

You can also re-hit the pinpoint button quickly while pinpointing and it will shrink down the field of the signal going into the ground and it will make for quick size shrinking of the precise spot of the target. This is not taking into account angles in the ground and such before someone lambastes me here, but it narrows down the pinpointing area under the coil for more accurate locating of said target. You can keep rehitting the PP button a couple of times if you need to to shrink it even more but after a couple times the signal may dissapear so then you have to go back to regular mode and start the PP over again so don't do it more than maybe 2 times. Alot of detectors have this feature but most of us either forgot about it or don't use it.
