F75 LTD 2------ID Numbers

[Coin Rescue Inc]

I have hunted heavy since the snow has melted an dug up 100 coins. No silver yet.
So I dug out a mercury dime, 1919 wheat and a clad dime to see how the numbers rang up with my 5" coil and my upgraded unit.
I wanted to zero in on what number the silver dime rings in at in a best case scenario. Coil 4 inches from coin.
Clad dime=75
1919 Penny=68
Merc Dime=78

I discussed this with Ron and he tried his unit and was getting different numbers.
Just thought this was worth mention. Everyone should learn their machine.

Yours are a couple points high of mine (or at least what they were before the upgrade). My dimes run 70-71 very consistently.

Individual machines and soil types probably slide the scale a bit.

I lost my little cheat sheet of what numbers were with what coin but they were all in the 70 to 71 range.

To beat all I lost my test target wheat penny out in the yard, still haven't found it. If I keep going like that I will need to start a reverse treasure log.

If it would have been my silver dime I would have had to call in my brothers.

With my f5 those silver dimes come in around 70 to 71, no different that the clad dimes , quarters silver or clad come in around 78 to 84 . If your not finding a good ratio of wheat Penny's to non wheat Penny's (I'd say one wheat for every 3 non wheat) then I'd suggest looking for new hunt sites where that ratio exists. Like tabman says finding the right hunt sight is paramount.

One problem: A merc dime may in fact read 78, but is it worn??? That's the problem a worn merc may only read 75 on your machine. Are you going to pass it up since what's under your coil reads 75 vs 78. If you do you risk leaving silver for someone else!!!!!
And this is with all vlf detectors even minelab. Just food for thought. And try this experiment, take a clad dime sweep it, then sand it real good and resweep. You'll see the TID start to lower.

The manual says you should be about 70 on a clad dime or copper penny. I have had 4 of these F75 and all have been real close to the ID 70 for a clad dime, silver dime, copper penny, now some of the older wheat pennies that are badly corroded were coming in at 68.

So I would say your numbers are way to high, I would do another test and make sure the detector is only seeing the coins. If it is seeing something in the back ground it can up average or down average and give you a higher or lower number.

If then you are still getting high numbers I think I would contact FT and see what they think.

Hi Ron
I checked the test spot prior to testing to verify if there was any other signals. If there was iron the numbers average downward not up.
I think my detector is super hot and working perfect. I like that the unit has a bit higher number on silver. I think that will give me an edge on identifying dimes. I know before the upgrade I would read a washington quarter at 88. I can do some more testing Saturday. Think I have another dime or two and see quarters and wheats and indians. I can also try my other two coils to see what they read.
I also like the idea that all dimes read the same. If that is true then it means I never passed up a silver dime.
I just threw this info out there to see what others see for a silver dime and why I have not found any lately.
This weekend I may get a chance to go to a group hunt where most if the guys use CTX and E-trac units at a 1910 park.
So I want to be sure I do ok. Last week they pulled 6 silvers out of the park. Park is in the iffy part of town if you know what I mean.
Thanks for the suggestion, I will keep it in mind.
was out yesterday for an hour after work and dug 25 clad coins and one wheat. 5 were clad dimes. On a clad quarter and one nickel. The nickel was 29 and the quarters are 83 84.

My F75LTD2 reads 2-3 points higher on silver quarter vs clad quarter. Haven't tried clad dime vs silver dime though.

With or if your numbers are really running high, you may want to check for the big silver problem. I can't remember if you reading about my brother SL 52 when he had that problem with his F5. I took a silver $ to the park just for him to check his ID numbers in case we ran into one. He could not detect the silver $ and ended up sending his machine back for adjustment.

So you only have 99 ID numbers and silver $ may wrap around and give you an iron reading.

Okay for you club hunt put the 5x10 on the stick, select BP processor, 3 tones or 3H, set disc just below nickels and run kind of on the slow side. Listen for signals not so strong and watch the depth readings. If you go over silver you will find it.

Good luck,

Ron

Good point Ron.
I have plenty of Morgan's and Walkers I can check the high side!

Numbers will vary based on alot of factors. I wouldn't put too much stock into them. Unless you're cherry picking in a very clean area, those numbers will vary if there are multiple targets in the same hole, be they good targets or have iron in there. Rust flakes can scew the numbers alot and you'll never even know it's there next to a coin. A coin will give a solid tone but lower ID if there's iron underneath it some times by several inches, and you may not get an iron tone at all and think it's trash by it's ID number. Just dig any repeatable non ferrous tone that seems coin sized if you're in an area where you find rust or nails or if you're strickly hunting for older silver.

I'm to curious to pass on alot of iffy signals and have buckets of trash to prove it, but I've also made alot of decent finds that way.

P.S. Coins are nice and always appreciated, but I've found that there's plenty more to be found in the relics area that are even better and more interesting, which is a good thing as silver gets harder and harder to find.

Tested a couple silver dollars and both at 95
Silver war nickel 33
1919 and 1944 cent 68
1955 D cent 72
Indian cent 55 to 60

I dug an 1892 Barber dime today at 8 inches deep and it showed a solid 80 VDI, the same as a silver ring I dug last week.

This weekend I found aluminum bottle caps are 60 just like the IH Penny. The old park hunt was pretty much a draw on locating silver. No one scored any silver. Starting to think operating in all metal reeeeaaaal slow is the key to junky parks unless you want to dig most every thing.
The three clad pennies, dime and Quarter, all clad where solid repeatable hits. Some thought the area was filled in with 8" of fill full of junk. Also found an key-chain and parts of a fence.
Rule number one- hunt where there are good targets.

My upgraded F75 is like learning a new machine. I only have one set of battery's through it and cant really report what Im seeing yet. I am finding nickles, a lot of them. I have my first gold ring too. Just too much effecting the VDI numbers to use them. I have been fooled by sound also. Even on a low setting your gonna dig. I still cant get over how quiet the upgraded detector is. I put the 11" inch coil back on, no need for the 5" inch coil any more.

I was in a new park Tuesday evening with the 5x10 coil. The ID numbers were too active giving me lots of broad ranges of ID numbers like 60 to 92 in multiple areas. Maybe lots of junk and few coins. A penny and Quarter. Also pin pointing was difficult to nail down location of target. So looking back the 5x10 coil was too large. I went back to the car and switched to the 5" coil. That worked a fit better and found three quarters and one bottle cap. Then off to the side a strong 84 signal was a foot long 1/2" copper pipe. So I think the park had quite a bit of junk.
Also went from 9.1 to 9.0 to see if that calmed things down. Getting mucho 90 to 95 hits that I don't remember previously. After testing last week a silver dollar at 95 maybe I am just to alert at seeing so many 95's. It is like the Brink Truck blew up leaving silver dollars everywhere and I don't have the will to dig up every one unless I bring a spade with me.
So at this point if I find a coin sitting in clean dirt it is crisp target easy to distinguish. If i get bouncy numbers it is a cap shoot of what I found. Aluminum screw tops come in like 60 to 78 too so I am starting a nice collection.
Snice the snow melted this spring I dug 140 some coins so I guess I can't be too critical but just a bit frustrated about no nice finds at this point. Maybe it is location, location, location.
