Pin Point mode 'discrimination'

[Knipper]

I learned this technique back in the early '80's from my detector dealer. He said it wasn't well known. We (hunting buddy and I) practiced it a lot and got good at it. It can even identify some aluminum targets but really excels at iron. Back then, almost all coils were concentric, and I found it didn't work for DD coils sweeping side to side. Recently, I tried it using the FRONT edge of the coil and found it works well that way for DD coils too. So, I made my first video ever about it. It's not profesional compared to some (I get tongue tied in front of the camera), but I think I illustrated the technique ok. However, on the E-trac, one must set the pinpoint setting to SIZING as opposed to NORMAL. Here is the link to the video...

Be sure to read the introductory comments, as they further explain method details and instructions! Please let me know what you think!

Iron can fool ANY detector, but this technique isn't fooled. It's limitations are when you encounter iron mixed in with coins. For that condition, the iron usually overwhelms the 'good' signal'. Also, it doesn't work as well in tall grass or vegetation, as it's best if the coil is on the ground, or at least very close to it. It's main purpose is to confirm iron and most aluminum in the hole, but works to confirm a conductive target too.
Give it a look and let me know what you think! Should work with any detector that has a manual, non-motion pinpoint mode!

Thanks, Knip.

My only problem with the technique would be knowing where target center is. Otherwise, interesting as hell, and I can't wait to give your advice a, heh, swing.

Yes, for this to work effectively, one must precisely pinpoint where the target is. Are you familiar with 'de-tuning' the coil to reduce the pinpointed area to a small 'blip'?

yes...but please continue the de-tuning method for all to see....good thread....please continue on.

@k-- no, i'm not.
