DISC on the V

[homebre]

Maybe I was mistaken, but I thought the DISC on the V wouldn't discriminate out silver until you are near MAX. Does it DISC out near gold which his below aluminium and above iron?

. From what I can see with my Vaq is, a sterling silver ring doesnt seem to disc all the way out, even at max. Definitely should not disc out near gold, unless maybe it's a very tiny piece of silver.
is yours disc'ing out silver near the gold range?

 

[allcav]

It can do that. If the machine is disc'ing a quarter out at the zinc side of things, that might be a little low. I would send that in for us to calibrate. If it goes out at about 9 or 9.5, That is very possible and could be in the normal range. Again, if that's not what you want, we can calibrate it.

Maybe I phrased the question wrong. It is not DISCing out near gold, it does DISC out near MAX. I asked th e question to be sure when I am hunting silver I can have the DISC set pretty far to the right (12 to 2 o'clock), and not miss silver unless it was very deep. Hope this is clearer.

 

[allcav]

Silver shouldn't disc out or should disc out very close to MAX. It shouldn't be anywhere near Gold.

 

[homebre]

That is what I thought, so if I am silver hunting I should be able to supertune and DISC out close MAX and not lose silver though I may lose some depth. Correct?
Thanks

 

[allcav]

Yes, I would put the disc level past pulltab. Around 2 O'clock.

That is were i set my disc,a hair past tab.This allows me to quickly locate silver coins with not much fuss with tabs and other trash.This method has really worked for me in finding silver coins.You will also get the older copper coins while at it.After getting all the silver out first,i will only then turn the disc down to the nickel range.And then go a little lower in stages. :-$

 

[BarberBill]

On all my Tesoros I often turn the disc up to max or near max after getting a response. If I still get a good response, I dig and nearly always retrieve a dime, quarter, half, or copper penny. Once the setting has passed the range where most other targets drop out, you can be pretty sure the target is most likely one of these coins. You definitely lose nickels, zinc pennys and most non-silver jewelry this way, but the coin percentage is very good.

You should do an air test, Bill. It only takes seconds to confirm what follows...

Air tests from a Cibola with a 12x10 DD coil sensitivity 10, normal threshold:

Discrim @ Iron
Dime 7"
Penny 7.5"
Quarter 8"
Nickel 9"

Discrim @ 1 notch before nickel
Dime 6"
Penny 6.5"
Quarter 7"
Nickel 4.5"

Discrim @ 1 notch before MAX
Dime 5"
Penny 6"
Quarter 7"
Nickel <discriminated>

Discrim @ MAX
Dime 4"
Penny 4.5"
Quarter 5.5"
Nickel <discriminated>

The moral of the story is that if you want deeper nickels, set your discrimination to just a little bit after iron. If you want heavy discrimination, avoid using MAX because it really hammers your depth.

Finally, I only have the Cibola - I am assuming it will be similar on your Vaquero. This model is really different from the Goldens - on the Golden, can adjust discrimination to just before nickel - and still recover nickels. On the Cibola, setting discrimination to just below nickel will result in most nickels getting discriminated.

I find that, with the Cibola, you can pick up more depth by cutting back on your Sensitivity. I rarely run it above "7" or so. Try it. The Vaquero is deeper by at least two-three inches with a stock coil in almost all soils.

I will give it a try, but I do have a manual ground balance mod installed on this Cibola and I ain't afraid to use it .

I have read a number of times where reducing your sensitivity helps detectors without a ground balance to handle mineralized soil, so I'd say that your advice is top notch.

RE: Air test - Topdecker
I''ve done lots of air tests. In fact I do them often to determine whether my detector(s) have changed their capability. I'm assuming that you think my post above meant that I hunt with high or max discrimination . I don't. I hunt with very low disc or in all metal, then turn up the disc to help determine the possible target. If you're pointing out the loss in depth of a high disc setting, I've been aware of that for a long time as well. In most parks, fair grounds etc. I often throw a nickel on the ground, turn the disc till I lose that signal, then back down until the nickel hit is solid and go detecting. That setting generally picks up gold jewelry and of course pull tabs and most other trash. If I'm mainly hunting for dimes quarters etc.then I pass the coil over the target again with an increased disc setting. If the signal is still solid, I dig. By manually checking where the nickel signal is strong, I'm ignoring where the knob may be marked for a nickel, rather than depending on that marked setting. That way I'm pretty sure I won't miss nickels or small gold.

I am totally stealing that! That seems like a solid, consistent approach.

This is what I can tell you. In an air test not super tuned, the quarter should be reached at about 9" and the dime about 7". I wont talk about pennies or nickles at this point. I tried this both with too + and too - and just right in the air. When you are too +, it looses depth considerably. These test are all with the disc level at min. We all know max disc will loose depth so I wont even test it that way.
I can also tell you that if your coil is out of tune, it could have the same effect. It could also be something in the circuitry but my guess would be the coil.
Please, before you decide to send it in. Even in an air test. Ground balance the machine properly or your results won't be right. You can also test this your self. If you are indoors, use a hot rock to balance the machine. If you don't have a hot rock, take it out side and balance it and do your tests out there.

Hi Robert I saw this air test-so I ran a check on mine
Hi Robert I saw this air test advice for the vaquero so I ran a check on mine-I had 3.5 turns on my ground balance knob-- so I set it at 1.75 turns off of the soft stop I think this is what the book says is a good way to start. Should be close to the middle postion for a starting point.

Threshold=full , sens=10, Disc=min quarter 10 - 11 in and dime 9-10 in-

Threshold=full , sens=full, Disc=min quarter 12 - 15 in and dime 10-13 in

Threshold=full , sens=10, Disc=beaver tail pull tab just past Nickel quarter 10-11 in and dime & copper penny 9-10 in, zinc penny 9 in, Anthony dollar 10-11 in and my cell phone 19 in. a droid x

I tried this with a half a turn- both with too + and too - and just right in the air. When you are too +, and it loose some depth

Eliminates any variation on the knob settings for different detectors and you know you're accepting nickels/gold range targets.
