Target Averaging

[RLOH]

What happens when you get your Tesoro coil over multiple targets close together? Today I had this happen with a wheat penny and buffalo nickel. As I swept the target, I got a signal that was barely below a zinc penny on the disc knob of my Tejon. It has been my experience that this type of signal is most of the time a beaver tail off a pop or beer can. I run my primary disc just below nickel and my alternate disc to just accept zinc pennies. When I get a signal, I quickly thumb the primary disc knob to just past nickel. If the signal is gone or breaks up at this point, it is many times a nickel. If the signal is still there, I will push the trigger forward to alt. disc. Today when I did this the signal was just on the border of being a zinc. Since things were slow and the target sounded deep, I decided to dig this "under zinc" signal. At about 7 inches, I found a wheat penny. The first thing I thought was why did the signal break up just below zinc. I first thought it was because of the wheatie being so deep.I rechecked the hole with my pinpointer and got another target the side of where the wheat was and slightly deeper. About two inches deeper and just off to the side was a Buffalo nickel. I have used detectors that would give two tones or numbers, depending on how you approached the target, but with a single tone "beep and dig" detector like the Tejon, I had not investigated this situation. It just goes to show that to learn how things work, you have to check the not so obvious. I had a fun day today with the Tejon and found a couple more deep wheaties. I have had the entire lineup of HOT Tesoro detectors and they are all capable of some serious detecting. I found my oldest coin ever with a Cibola. It was my oldest silver and oldest coin, a 1780 Spanish reale. After trying just about every detector made, I still find Tesoros to be the best bargain in the hobby.

Thanks ROLH. Great post, and I learned something.

I've dug some nice surprises when the TID indication bounces all over -- often turns out to be a coin spill. Also with beep and dig or ID detectors have often been glad I dug when a sound just wasn't quite right. By that I mean it didn't sound quite like the typical trash, nor quite like the clean tone of a good hit. In the end our eyes are the only sure discrimination.
