*** LOW SILVER COUNT !!!! ***

[cloudbuster]

Hi Chaps and ladies, i am gettin a little concerned over my silver count. My sovereign mate is hitting way more hammered than me and i have to say my silver count has dropped quite significantly since moving from the XLT to the V3. I have tried one or two different program tweeks and have settled on a slightly modified version of the relic program. i am generally running at 8-9 on rx 85 on discrim & 65 all metal, as for mixed mode i slip in and out of that depending on how trashy the area is. Most of the fields i am working have unusually low trash but very high coin count. I have used both super 12 & the 5'3 coils with both finding targets at much greater depth than the XLT, yet on many occasions the targets i am hitting are only just below the surface (stubble fields).

I seem to have no problem finding copper coins and id'ing them without question but the silver stuff is eluding me !!! i have tried the deep silver program but its just to unstable !, am i missing something ?????

The only program I have any experience with silver is my modified coin program (probably close to coin&jewelry) since I opened up the discrimination.Also the D2 coil is the only one I have right now.
The biggest improvement for me came with setting the ground filter to 5 and increasing the recovery number and swinging slowly,probably less than half the speed I would with the filters set at 10 High.With the deeper silver you may not get the VDI reading your used to.Watch for a lower VDI with 2.5 dominating or 2.5 and 7.5 close together while pinpointing.If its really deep,all 3 frequencies might be fairly close together.On dime sized US coins weve been hitting +53 +54 VDI and digging up the silver,as pointed out by Pat in On.Not sure what your coins will read,but keep an open mind.

I can think of a couple things to try that might help-
1) Correlate in 3 frequency might help. Might need to turn correlate wrap on and adjust the limit for your conditions. It's possible that your 22.5kHz frequency is wrapping around causing them to be missed.
or
2) Run single frequency 2.5kHz or 7.5kHz. Silver should hit strongest on 2.5k, but 7.5k should also work and might be better for the other coins you're finding.

ETA: I should clarify - this might work for the big silver targets. Silver dimes seem to be coming in the coin range. But, my silver half dollar that I have wraps around. One more thing (assuming the bigger silver target), keep in best data and 3 frequency, and accept -94 and -95 and set the tone for those 2 VDIs to the dollar tone.

Many thanks AK ...have tried single freq but will try accepting those couple of missin VDI's ....one point though, all of the silver i have hit so far have been at the lower VDI numbers from approx 25 through to 80 depending of silver content. most modern coins seem to hit in usually around 28 and the odd hammered that has been found at 38-40.... i have found this a bit odd as the values were always much higher on my XLT. all copper seems to come in between 52 and 84 again depending on alloy content (most older coins 57-7... another minor point, the initial readings are often much lower than the reading i get before the sod is removed.This has happend on a number of occasions especially with small bronze coins which ring in at 52 then jump to 78 or even higher when the sod is removed.

i check ground with probe quite frequently and noise is usually 0% with signal loss always under 10% !!!!

Don't lose hope. Keep tweaking.
I too am struggling with the V3 but I know that with all the adjustments one can make to this machine... it will out perform most other machines once I understand how to use it properly and once i'm more experienced with it.

You will be able to make changes for each site while the Sovereign user will use pretty much the same settings everywhere because there isn't that much to tweak on a Sovereign, I think the Sov is a good machine... oine of the best BUT I think that the V3 will out perform it in the hands of experienced and knowledgeable user... (that will be you in time) and hopefully me too!

I agree with what someone else said about lowering your filter to five and raising the recovery and slowing your swing.

You might also try getting a buddy to call you over when he/she has what they think to be a deeper silver target and let you try tweaking the settings until you get the best target response with the V3. You can also see how it is responding with the warp around if you do that.

I am mostly using the D2 and the 5.3 and I am not sure which I like best. I have to lower the RX with the D2 but then it works well. Can you raise your disc sensitivity if you lower your RX a little? The DVD says that a higher RX gets more depth but Jimmy Sierra and others say that the disc sens gets more depth and that the RX only amplifies what you are already hearing, sort of like the "gain" on a ML ET or SE. I'd say if you are hearing OK, lower the RX and raise the disc sens but I could be wrong.

Watch your voltage too. I don't know at what point voltage drop affects detection. Some say one thing snd some another but if it hits 8.5 i'd swap it out.

How is your normalize set. I think in single 2.5 the top range is expanded with normalize off but I haven't fooled around with it and I could be wrong. Could a normalize setting be making the silver hit lower than usual? 22.5 without normalize expands the lower numbers and compresses the higher numbers... I think. I'm sure someone will clarify this but your normalize setting could be monkeying with the VDI numbers or could help make them be more what they were on the other machine.

?? Someone?

Interesting thoughts J, theres so much to experiment with on this detector.It'll be interesting to see how it acts in 3 frequency best data with the 2.5 normalized off.Or for that matter with any combination of the frequencies off.I have a feeling I better keep a notepad handy.

I tried running same program in single freq today (2.5mhz) but had a real hassle getting the tec to stabalize. RX gain had to be run right down to 3 to get her stable !!! trouble today the field i was in first part of the day all targets seemed to be only about 3" or so with very few good targets to do any analysis. the field only yeilded two coins and both were copper. I have tried using the same prog with -95 -94 -93 allowed to see if wrap is an issue but just got more iron signals. i think the only thing to do now is bury some test targets and just play until i get the best results. i have a few hammered and some pre decimal crowns and stuff which i will do some testing with tomorrow.

will keep you all posted !!!

if its any help ive found hi-pro is quite good ive found hammered with it even part of one plus cut halfs have included a pic.im still playing with settings but it does find the small stuff.
