Tejon For Coin Hunting

[RLOH]

I finally got my Tejon out to a spot where there are many coins, but with a fair amount of modern trash. I set my primary disc to the slash below nickel and the alternate disc to accept zinc pennies. I ran the sens at 9 and was using the stock 8x9 coil. I stepped out of the truck and went less than 10 feet and got a signal that was solid in alt disc. It was a 46 wheatie from about 4 inches. I worked my way up to the football field and was plucking clad coins every minute or so. When I got to the field, I went to an area along the sidelines, bordering the end zone. I had hunted this area hard last fall with a F5 and my Explorer 11 so I was not expecting too much. I was hoping to find some of the older coins that all have been in the 8 inch deep range. I was steadily getting faint whispers in alt disc and I kept digging them only to find small pieces of wadded up gum wrappers in the 5 inch deep range. I was getting tired of digging these signals and I knew there had to be a way to distinguish them. Finally one of these signals turned out to be a silver roosie from very deep(8 inches). What I found on this whisper of a signal was you had to sweep the signal six or seven times. This silver dime stayed consistant, but faint every time I swept It. I tried this method on the next batch of signals and found out an interesting trait of the small foil. The first couple of sweeps over the foil, the signal sounded good. After three or four sweeps, the signal would start breaking. I dug a half a dozen of these types of signals and all were the foil. I ended up getting a couple of more wheaties that stayed consistant in alt. disc. I came away very impressed with the depth of the Tejon as well as the accuracy. The deepest coin was an honest 9 inches deep and was found in the same area I had hunted in the past. Now for the killer part of this hot detector. I got two solid deep signals that were somewhat louder than the kind the coins and foil were making. They were both brass band uniform buttons and both were over 10 inches deep with plendty of muscle to spare. After learning to trust the Tejon, I dug very little trash. One more bit of advice on this detector. Use good headphones or you will not be able to hear these deep whispers. I use the old style Ratphones and now that I know what to listen for, I will be finding many more deep coins. R.L.

Hi RLOH,

I've noticed what you are talking about, after sweeping the coil over a deep target numerous times "seems" to make the signal sound either broken up or more repeatable. I used to think that it was the disc. circuit that was given more time to sample the target signal, but when I go to all-metal to size up, shape and sound of the depth of detected target, then change modes to motion disc. Then the deep target sounds stronger. I don't know but I think this phenomenon maybe just target saturation from electromagnetic "Eddie Current" making the target more susceptable to positive target signal

RLOH,

I'm a new detectorist using a new Tejon. I was out yesterday for a while looking over a very trashy area and noticed the very same thing. The marginal targets sometimes seemed to break up and almost disappear after a few sweeps, and were then harder to pinpoint. I was digging gum foil down to 4 or 5 inches. However, that Tejon was strong on the heavy aluminum wire or that 3/4" piece of #14 copper wire down six inches, that someone had snipped of who knows how many years ago. My Tejon really wants to "talk" to me and I can see that it will take a while to learn how to listen to it.

Thanks for the tip.

Hombre, I never thought to check the signal in all metal. I do know that these deep coin signals will remain after multiple sweeps. I wish there was some way to let people hear what they sound like because they are very faint. I use to use Fisher CZ's and they had a feature that with the volume 5 and below, the audio was modulated. Above 5 all signals sounded the same(loud). I prefered knowing how deep the target was, but you had to have good phones and hearing. In the case of CZ's, the high tone indicating a coin was barely a "tick". The deep coins with the Tejon seem to be almost the same. The good thing is that once you are tuned into what they sound like, you will not miss them. I have had many Tesoros over the years and I use to doubt their ability to go deep. Now I realize that they were telling me something, but I was not hearing it. R.L.

Mike, it sounds like you are analyzsing different scenarios and that is a good thing. I am the same way. If I am constantly digging a certain type of signal only to find it to be junk, I start looking for slight differences. I do not pretend to be the "brightest bulb" around, but you are never too smart to learn a trick or two. Hombre brought up a great point of checking in all metal. After you get use to any detector, you can learn how big a target is just by how it sound while pinpointing. The more I use the Tejon, the audio starts giving hints of just what is under the coil. Yesterday I dug 10 nickels and toward the end of the day, I quit thumbing the disc because of how they sounded and pinpointed. Nickels definitely have a signature sound with the Tejon. Keep plugging and trying different things. Good luck. R.L.

I kind of thought that maybe there is a bit of a settling time on the discriminator circuit. Most of the time, I'll take along a pop tab that I pulled off a soda can and set up the second disc so that a few swings after pulling the trigger, the tab crackles. When a nickle is under the coil, it disappears about as soon as the trigger is pulled. That, gives a pretty nice mid-conductor range split for target ID's. Most hunts I'll dig the target anyway. Always nice to turn up jewelry or the odd token or foreign coin that isn't right there at nickle.

Congrats on the deep silver dime. Sounds like many more will come for you.
Cheers,
