Newbie questions

[mwaynebennett]

I have now spent several hours with my BH Elite 2200 and have some questions.

1) Why is it that sometimes I get different tones depending upon which direction the coil swings?
2) Why is it that when I get a good signal and then I turn 90 degrees and swing the coil I sometimes get no tone at all?
3) How accurate is the depth indicator? I keep getting a indication at a depth of 7 inches in one particular spot but after digging a hole 11 inches in dia and 15 inches deep, I still get a signal of 7" down which would be in the middle of thin air. What's with that?
4) Since gold and pull tabs have similar conductive/electro-magnetic properties, should all pull tab indications be dug?

Thanks,

Mark

1.depends how an object is lying in the ground, perhaps two coins, coin with junk..coin which has properties.which fall into two tone facets.
2.Usually this is a junk target and on any unit if it don't repeat leave it lie..Could also be a tilted coin or coin next to junk but rule of thumb majority of time its junk.
3.Depth is fairly accurate for coin size objects but it appears you have hit a large deep object perhaps a underground pipe or large piece of junk.
4.To dig every tab signal in the park you would never get off your knees but those that imvestigate usually get the gold rings others miss. In addendum most detectorists find a way to cut down the odds by tone, audio response crisp or not, or perhaps a gut feeling but gold rings are just tough to find due to all the junk that imitates them...

About two weeks ago I buried a 1959 US penny, a 1955 US nickel and a 1960 Canadian dime. I placed them two feet apart and I know exactly where each is located. They are all lying flat about three inches below the surface. What bothers me is that each gives a identical signal,,, iron using my BH Elite 2200, If A person were to ignore all iron signals, he would miss these items.

How is one to overcome this problem?

Thanks,

I checked out from the library some books and got some answers.

1) With the auto ground balance, a junk target can upset the stability one way and not another. Often times it is a long iron item like a wire or a nail. Such are to be ignored.

2) Again, it depends upon the shape of the item. This is usually caused by a long slender item made of iron.

3) Steep sided holes can also trick the ground balancing circuit. The hole I dug had vertical sides and such may have created a phantom signal. Using my Harbor Freight pin pointer, I swept the hole and got no reading so I suppose there is indeed nothing there.

4) Most likely, all pull tabs/gold ring indications should be dug.

ITS ONE MORE REASON TO HAVE AN ANOLOG METER
DIGITAL BOUNCES TOO MUCH
