F75 - VDI's - Deep Silver Coins?

[Bunzee]

I have a F75SE. I've only had the metal Detector for about a month. I haven't dug any real deep silver coins. Do you dig targets that Jump from say 92 to 70 to 40 then back to 90? I think I may be missing out on some good finds by not digging these. Anyone want to share some tips?

Deep silver is and gold coins are nearly mythological. I've never found either. I have found maybe 8 silver coins, but none were very deep. If you find out the secret, let me know. I've spent a lot of money on equipment and batteries and time spent trying to find some.

i wish i could help. i run with the F70 .the machines are similar in a sense. different bells and whistles.i find bent square nails with that jumpy signal sometimes...............but you wont know unless you dig it up. just saying. goodluck and happy hunting ....Tim

WHAT setting s do you run ??????//

The 75 is a very capable detector. You do have to be hunting where the deep silver may be though.. depth is also regional thing..Some areas Silver is deeper than other areas of our Great lands..

Where are you hunting ??

Bunzee, go to the Teknetics forum....read post titled "low high single". Its along the same lines as your question here, to what your asking. A F75 & T2 behave very similar in certain functions.

That type of signal I generaly wont dig unless that high tone repeats itself more so than the lows,like mentioned,if in doubt dig! Also try flipping over to all metals,I keep my all metals settings hot so any doubts I may have are almost always confirmed doing this.JMHO..hope this helps....hh rick in mi.

Deep silver with the F 75 is almost tone only. For old coin hunting, I mainly use 3h and 4h tones and listen for those high tones. Although in my ground the vdi isn't to bad on 7 and 8" coins, it is jumpy. If, though, it is a repeatable high tone I dig it. HH jim tn

 

[shilohwig]

if it repeats i dig it i hunt 2 tone though i have dug deep silver that jumped around and a gold coin that was jumping 40s to 30s and i get alot of bent nails to but i cant stand not to dig it if it repeats

 

[jim tn]

Tone(s) is somewhat a matter of preference and 2 tone is good. I mainly old coin hunt along with some relic and the high tone alerts me to really investigate the target. When relic hunting, it is pretty much dig anything that beeps. I also find if I get the target centered good under the coils sweet spot it puts the vdi numbers into a tighter grouping. HH jim tn

In all of my real-world evaluation(s) of the F75 SE........... the most pronounced effects are with the 5" DD coil..... and in any of the 'boost process' modes (ie 'bp' or 'cl').

A additional sensitivity enhancement/boost program is employed when Disc is set at '4' (and lower). With a more rational Disc setting of '5' ...... the sensitivity is returned back to normal levels. When Disc is above '20' ..... due/because a lot of chatter is reduced......... this allows for the sensitivity enhancement/boost program to be employed again. There is justification for this engineering intent. Most folks would not understand this rationale ...... or even know it exists; yet, Dave Johnson is on top of engineering attributes that many would never have reason to think thereof. There's plenty of other attributes within the programming logic of the T2/F75 architect that are 'behind-the-scenes' ....... and most folks may never discover it. What's (underlying) is............ as you become more of a seasoned detectorist and delve into the 'professional treasure hunter' category..... then (and only then) do you start to become more 'demanding' of your unit...... with additional required performance/programming ........................................................ only to discover ............................. these things have already been 'thought' out................... AND are employed in the detector. This is called 'forward thinking'. TD

I know what you mean. I've only found two silver coins in the last two years, both only about 3 or 4 inches deep. But I did find three gold rings and 8 silver rings last year, so there is hope. There is a poster on the web who says he's found over 280 silver coins so far this year. He hunts parks in Southern California. Still not sure how he does it though. He says he hunts really trash infested parks that have been throughly hit many times in the past. I think he's developed an ear tuned into certain sounds. He says most of the silver he digs is deep and have iffy signals and VDI numbers. But what is "iffy" to me or others may be a megaphone to the trained ear that silver is nearby. He didn't go on to mention if he digs a thousand holes a day netting 6 silvers. But I think he digs a LOT of holes.
Good luck and have fun and I believe somewhere there is a silver coin with your name on it just waiting to be found.

I never found any deep silver with this machine, but have not really looked for it either.
I have found some dimes in the 8" range with a CZ-3D.
Honestly, most silver I have found comes in at about 5" on average with any machine I have used.
I have dug some deep "whatzits" and such with the F-75, so I am sure it is capable.

Like I was saying to someone the other day--first you have to be in a place where there is deep silver.

Also, you need to really try your new unit out somewhere where there is a mix of deep and shallow clad, so you can get a good feel for what it is trying to tell you.
I always go by tone, but the VDI is pretty much dead on.
As always, solid repeatable tones I dig.

Try finding a clean park from the 40's or 50's that is grassy and was trafficked heavily---be a great place to find a deep one.

I see everybody is using the term deep silver, nobody is giving a number as to what deep is. But since I got some advise from Dave J I have been getting some silver just about every time out. Basically he said I was trying to run my machine to hot.

So I did a factory reset on the machine and I have been running sensitivity 60, 3 tones, max disc (65) and right now I am only digging repeatable targets. So far the silver and wheat pennies are reading 7" on the detector and when I dig them they are between 6 and 7 inches, so far every time. And I might add I am hunting in a park that is hunted by all and I have found a lot of plugged holes, but I am still getting the silver and a few older coins, I got 1918 nickel, and 1859 penny the other day.

Once I get an area cleaned running high disc, I am thinking I will go back over it with a lower disc and one tone.

OK I was thinking 6+ but Ron if that kind of results is possible...
That is in boost process right?
Tom the VERY impressed!

 

[Elton]

I always found lower sens seemed to hit better at old schools saturated with junk....... If sens cranked up the reflection/ Saturation hits on Deep junk seemed to hit too.

I dug my first Draped Bust cent 1803 a few weeks ago with those numbers. At anound 9 or 10 inches with iron in the hole.
If it goes mid to upper 90s then into the 20s i might pass on it . mostly iron
This is mostly old site/ field hunting in mild ground.

Tom,
When I got up this morning I remembered I didn't say in my post what processor I was using. But your right I used the boost processor and also I don't try to scrub the ground. In the park I am hunting I just kind of bush the grass just deep enough that I am not getting a lot of drag on the coil.

I have got several targets that read in at 10 and 11 inches, but so far all have been something in the small trash line and I find it on the way down at 0 to 4 inches.

I also know that I am cherry picking the silver which means I am leaving the stuff mask by junk. But the way I look at it is if I try to take it all out on the fist run, it will take me forever plus 2 days to work that area.

Ron good to see your getting a handle on your machine.
From reading your start with it , i though it might be a quick ending.

gmanlight, Thanks

My F75 has was promoted from 3rd place to 1st place in my line up.

One of the toughest things to get a grasp on is the amount of targets you hear when sweeping.

The processor reset and detect is so fast you honestly hear targets that other detector brands except teknetics do not hear..

Some even think, and or at least thought when the F75 first came out the detectors were defective.. They were not.Just doing what Fisher claimed..Detecting targets in the ground. LOTS OF TARGETS.

Fisher also stressed that the audio, and the Digital Id is independent of each other..Something we all forget from time to time using the F75..

I listen for high hits as I run 3 or 4 tones.then slow down and isolate those sounds.........The display hits so fast there is no way one can watch the display and expect accurate ID.. near impossible..

Yes it helps Id targets, but that is just what it is..One of the deciding factors of dig do not dig... You'll get it my friend. You have shown us all you know what your doing in the Hobby.... It's just matter of adapting to the F75.........
