VDI Display on Tesoro Machines

[harvdog42]

Hello All,

I frankly haven't done much research on this subject so I'm throwing myself on the mercy of the court. (You guys) I used to have a a Whites DFX and I miss the VDI numbers. I have a Tesoro Cibola which I really like and have found a lot of stuff with it but the discrimination knob, while it can get you in the ballpark will not give you too precise an indicator of an anomalous target. For example, with the DFX, a reading of 34 will very likely be a pull tab. A reading of 25 will very likely be a nickel. Any clean signals and readings near those ranges are definite dig signals for me as they may be a gold ring. The ring shown in here hit at precisely 29 on the VDI screen of the DFX. An anomalous number.

Granted the deeper the target the less accurate and less stable the VDI reading will be. The ring shown was only about three inches deep.

I like the simplicity, light weight and fast response of Tesoro detectors. So my question to you guys is this: Will a VDI display on a Tesoro detector give precise numeric readings on standard targets such as nickles, zinc pennies, dimes and quarters? If the answer is yes, then I assume it will also give precise readings on anomalous targets. That is if they are not too deep. Also what is the range of the VDI numbers on a Tesoro? And can you notch out just certain numbers with a Tesoro?

Any input on this subject would be greatly appreciated.

The screen on my Cortes shows both the target ID number and the catagory. A zinc penny and a screw cap are about number 80, see attached photo. Nickles are about number 40. Ladies and mens gold rings can be numbers 14 to 63, depending on the size of the ring. The info across the top of the screen in the photo spells out "zinc cent - screwcap", giving a broad reading. The Bars will narrow it down a little more and the numbers will narrow it down even more. I pasted the white paper sticker over the original Bar labels to make it easier for me to read. I also have a fisher ID Edge, the screen shows numbers only (no catagories) and so I must memorize target numbers. I like both detectors but prefer the Cortes, it gives more screen info and it has knobs rather than pushpads. Hope this helps.

I find the numbers to be pretty accurate. Especially when correlated with the ID segment, even more so when using SUM. But the notch windows are not extremely specific. The narrow notch knocks out most beaver tails, and the wide notch knocks out square tabs. A smearing of segments usually means junk. But yes, Tesoro is over due for some new technology. Or are they...?

Jabbo,

That helps alot. Thanks. I noticed the two notch widths on the detector. Can you tell me the range of numbers that the narrow notch will discriminate and the range of the wide notch? Another question: Will the VDI numbers still show up on the display when they are notched out? I'm hoping your answer will be yes.

Also, could I use the coils from my Cibola on the Cortes?

In your initial post you stated:

While it does have a "segment" ID at the top to suggest dimes and quarters, etc., the Cort

Harv, the Narrow notch nocks out most pulltabs, still keeps ladies gold rings, bracelets. The Wide notch does the same range but goes higher to knock out screwcaps also. The screen still shows all the info about the target, only the audio is knocked out when the notches are used. The regular Disc knob can be set at the same time to knock out iron and foil. When either notch is used, heavier gold rings (mens rings, class rings) will be knocked out too. Cibola coils won't work on the Cortes. Hit the switch and you are in and out of notches. I love the knobs and toggle switches, easier than pushpads. Ladies gold rings range from # 15 to # 35, pulltabs range from # 42 to # 63. Mens gold rings range from #49 to # 62, like pulltabs. Broken off tabtails are # 32, they fall in with Ladies gold rings and so they sneak through the Notches. Nickles are # 40, just barely out of the notch range. Broken tabs can sneak through the notches. Shredded cans (smaller pieces) can sneak through too. As you can see, Nothces have their limitations.

Having read Mike Hillis's articles,as well as others, I have to feel the Golden umax is what the doctor ordered. It is claimed they can even tell what kind of PULLTAB they have located. I love the tones on my Royal and can imagine what 8 (or more) tones would produce as far as ID-the trick is setting them at the correct break points. AND, tones are faster with no need to glance at a meter. Since most gold hunters don't use notch, there could be a Golden, Jr.-a detector that would have only the tones, with the ED-180, and a width control to set the break points on the tones.

well on my Deleon i had i can say that my numbers were very acurate and the only thing that wasn't was depth meter never payed much attention just lifted my coil and got an idea then
