Whats it trying to tell me?

[Tim-MXT]

Pretty new to detecting and trying to learn. I have a White's MXT with a 300 coil. I was out hunting a local field today and dug a couple holes with nothing in it. The White's was reading 72 to 84 consistent over the spot in each direction. PP told me it was about 4 inches down. I dug down a good 8 - 10 inches and found nothing. Ran over the spot again and still get the same reading in the same spot at the same depth. 3-4 inches down in the center of a 10 inch deep hole. I used my White's pin pointer and it told me there was nothing in range. What am I missing? Could it be a much larger item much deeper? I stuck my digger down in the soil another 6 inches and didn't hit anything solid. Is there something I may have had adjusted wrong on my machine? With the same settings I was able to pull out 2 quarters and 2 pennies and the machine was fairly accurate about the depth. Any ideas why?

Thanks

Had that happen to me yesterday. About the same vdi readings. I was on my property and finally got mad and dug the hole a lot larger and found a piece of brass 7 inches to the left of where the detector was pinpointing. Halo effect maybe?

Try lifting up the coil a few inches when pin pointing.. if the depth does not change it is something BIG and could be DEEP.

This toy truck read 78 on my coinmaster GT and said it was 4" down.. it was 13+" down

Doesn't have to be deep. Could have been a target very small on the top of the ground. All icons, VDI numbers and depth reported are based on coin sized targets. A small piece of melted alum, a 22 casing,etc can be very deceiving laying on the surface and can be flipped or brushed away when you start to dig. Happened to me many times in the woods.

The pin pointer should find a surface target so I suspect it's a big target down deep. Your choice whether to dig or not. If it's on private property that you have permission to hunt, I'd dig it....regardless of depth. It could be a nice cache! If it's a public park, I'd probably pass. The beach, It's probably junk but the digging is easy so "maybe" but not likely. It would depend on how tired or bored I was!

Tim, this is something that relates to sounds. And since there is no way to convey sounds through printed text, it's nearly impossible to answer. You know, like someone says "I hear a sound (or a 'signal') yet nothing's there" or "disappearing signals" and so forth. But since no one can hear/see what you're reffering to (the way you swing, the way you isolate, your swing speed, what you're hearing, etc....), then ...... no way to really answer.

Thus the best way is to hook up with someone proficient, in your area, to trade off flagged signals. Let him un-plug his headphone jack. See how he swings. What he passes versus what he chases, etc.... Conversely, you show him supposed targets. And if he says "I'd pass it, it's not really a "signal" and so forth, then ask why, and try to learn what's up.

I mean, even things like repeatability in-the-exact-same spot factor into it. Again, nothing that someone can convey in printed text, no more so than I can describe to you the sound of c-major, in printed text. Can't be done. Has to be heard. So hook up with someone in your area who routinely comes in with the oldies. Go to a spot prolific with easy clad, just for practice.

I have had this happen. When it does I fill in the hole and scan again. If I still get a signal, I scan until I think I have the loudest signal. Sometimes it is not deep at all. The pin pointer picks up a signal from the sides also, and can fool you into thinking it is deep. I put my pin pointer around the sides and sometimes I can find it that way. Have had some very small targets, like a bb, and I am so stubborn I don't quit til I find it.

Thanks for the tips everyone. It seems the MD pinpointing will take some getting used to. I was out again today and dug down on a strong signal. About 4 inches deeper then the object was. The handheld pin pointer hold me the object was to the side. I dug over there and pulled out an old horseshoe. Same thing a little later. Turned out the object was a galvanized nail about an inch under a fern. I dug down 8 inches. Maybe I need to use the handheld pin pointer sooner on the questionable targets. Again, Thanks for the input.

The larger coils can be a bit problematic in poinnpointing closely and are also more likely to pick up a nearby trash target due to their expanded coverage.
