6 x 8 SEF Pinpointing Question

[utmike]

I really like this coil but have hit several coins with my pick lately. I've air tested in pinpoint mode but am still a little less than confident where the "center " of the coil is. With my accelerator 6", I know exactly where the target is under the coil. The SEF just doesn't seem as accurate in pinpoint. Anyone else experience this? Thanks in advance.

Using the wiggle back method, determine where the signal ends. Mark that spot with a golf tee. Now sweep with the coil and see if the tee location coincides with the CENTER of the coil. It will. But do this to see for yourself...ALL coils made will be the most sensitive at the center of the coil, unless someone can show me with video evidence to the contrary. It doesn’t matter if it’s DD or concentric, square or rectangular or circular or hexagonal....ALL of them.

For me I stopped using the pin point mode on the detector, I just couldn't get a good PP. So now when I have a target I just do a few short sweeps and watch the depth scale on the detector. The shallowest reading is X mark the spot.

Works pretty good for me.

I completely agree with IDX and can attest to the fact that the coils are most sensitive in the center of the coil. As someone who gets a rush out of chasing super deep targets in our dense soil,
I notice it is one of the factors in why a site is never completely hunted out. I use the pinpoint once In a while to try and verify the size of the target but almost always just use the wiggle method
on deep targets from different sides to visually center my target.

Thanks Ron! And thanks for your service! 68-71 was a tough time.

I'll be practicing this a bit more. The excellerator was so accurate in pinpoint mode compared to the SEF, in my opinion. But, the 6x8 has really nabbed some keepers. Thanks for the tips!

Thanks Dave! I'll be spending less time on the PP button with this coil. I'm impressed at the depth I get in my soil with this smaller coil. A lot of the places I hunt are construction and ghost towns thus the small pick for hard ground. Don't want to dig big holes but don't want to nick my target either.

You cannot always expect the target to be laying NORMAL to the plane of your search-head;

If So, then pin-pointed position WILL be displace in proportion to that angle-of-INCLINE, and relative alignment of sweep.

Do a 360 degree sweeping Pin-point; and if the 'center' varies, then be aware and cut a broader hole.....matt

P.S Any null-point or minimized response during the 360 degree rotating sweep, indicates the target's 'narrow-profile'.
i.e. Coin on laying at an angle on edge.....or sweeping 'along' a 'narrow' target.....long and thin...relatively.

Excellent Matt, absolutely correct and a needed side note to this whole pinpoint thing. Being able to use pinpoint to judge target size/shape/position is actually “next level” stuff. It’s talked about at times but relatively few people use it(or are skilled enough to use it to produce repeatedly favorable outcomes). This just reinforces the idea that there are MANY facets to detecting...and not all facets are obvious or easy!

I hadn't considered that aspect and it makes perfect sense! Thanks for chiming in on this, I bet I'm not the only one that will benefit from your post.
