Having a hard time with new Cortez help Joe USA or anyone!

[Jim 2.0]

I am hunting an old 1920 era school in my town. It is somewhat trashy but I feel there should be some old silver coins. Hunting in Disc mode between iron and foil, sens high, I am trying to concentrate on 6" plus silver coin signals. I had a number of these today but came up empty on all of them pinpointing seems to be hit and miss to say the least!. I know this is a good unit, so it must be me! (this is my first tesoro, still learning) Also, I get a repeatable silver (95) signal in disc mode but lose it when i hit sum mode. I,m confused right now!

I'm still learning mine, but have you tried lowering your sensitivity? And ground balance it and try searching in all metal?

 

[Jim 2.0]

Yes, SusanMN, actually started out in all metal...too many signals, went to disc, even switched back and forth! park may be too trashy for my standard coil. However, even when I thought I had a good coin signal, I started to dig and would lose signal. Also ifffy pinpointing??

thanks for reply, Jim

Hmm, beats me. Ground minerals? Overhead wires? Loose coil wire? Those and too high sensitivity are the only things, except a bad coil, that I know of that can cause falsing, which is what I assume you are experiencing. As to the pinpointing, everything I've practiced with has been dead center under the coil's center hole at the point where the sound was the loudest, so I can't help you on that. Maybe you should call Tesoro on Monday? They were very helpful to me and didn't laugh when I couldn't figure out which way the battery packs went in - mechanics is not my strong suite.

If you only want to find silver coins try using more disc, maybe even above Tab, this will help get rid of a lot of trash signals. After you get the feel for it, back down on the disc. Are you using a concentric coil? If so you should be able to X the target and hit it on center most times. Check to see if your setting the GB correctly. Read and reread the manual, and get some time in with that machine .

L have only had my Cortes for a few days, so take this with a grain of salt. It seems to like rusty iron, it gives 95 signals on large pieces of iron and they can be deep. All detectors have trouble with this, at least the ones I have owned. Usually you can tell its something big when you pinpoint. I think its a learning curve for me anyway.

I would be willing to bet that this hunting spot is very trashy with lots of iron. My suggestion is to NEVER hunt in a high trash area when you are learning a new detector. Leave that school yard for when you get 40 or 50 hours on that Cortez. When the Cortez reads a "95" but it disappears when you go to sum mode the target is usually heavily corroded iron junk. That 9" X 8" coil is bridging several targets at the same time. If you do work that area in the future you would do better with the 5.75 concentric coil. Also you should not be running the sensitivity on high in that type of situation, turn it down to about 1/2. When you get a seemingly good signal lift the coil and rescan,also sweep from several different angles,then check the target again in sum mode if it looks good. Joe
