Fors core/gold VID

[AcDigger]

Hello everyone. I recently purchased a fors gold and have used it a few times. I am really enjoying the machine and I am learning it quickly. However I remember seeing a post on here about the VID numbers but I can't seem to find it again after using the search feature. Would anyone care to comment on what kind of numbers you are seeing out of various coins/targets? So far the pennies seem to be ringing in around 83 and I think a quarter rang in around an 86 or 89 I can't remember exactly. I know there is no substitute for getting out and really learning the machine and digging the good tones, but comparing the numbers to what I think is in the ground is half the fun to me. And having an idea of what number goes with what coin would be a tremendous help. Thanks and Happy Hunting

Hello everyone. I recently purchased a fors gold and have used it a few times. I am really enjoying the machine and I am learning it quickly.

The FORS CoRe/Gold models are easy to learn and even more fun to put to use afield. I have 3 Makro models and 6 Nokta models in my personal detector arsenal, and they might not have been there if it wasn't for the FORS CoRe I got 25 months ago and the excellent in-the-field performance it provided then and continues to serve me today.

However I remember seeing a post on here about the VID numbers but I can't seem to find it again after using the search feature.

The VDI [size=small](Visual Discrimination Indicator)[/size] of any numeric read-out detector will never be 100% accurate due to several variables, but it isn't too difficult to learn the 'general' VDI response from common coins as long as the coin is:

• Not made of a magnetic type metal such as Steel, Iron or Nickel. That is a problems with most common coins found in Canada and dome other countries.

• Not positioned at an odd or abrupt angle, but is instead laying in a relatively 'flat' orientation to the search coil.

• Not located too deep for ample signal for processing.

• Not located too close to another metal target, either ferrous or non-ferrous.

• Made with a very uniform, consistent alloy content and isn't well worn or deformed.


It is also important for the operator to have and use:

• The best functional detector for the particular application.

• Proper detector settings and not use too much Discrimination..

• The best search coil size and type for the site environment.

• The proper search coil height and sweep speed and search coil presentation [size=small](thorough coverage with ample overlapping)[/size].

• Also to understand the strengths and weaknesses of different search coil types [size=small](Concentric vs. Double-D, etc.)[/size].

Would anyone care to comment on what kind of numbers you are seeing out of various coins/targets?

Keep in mind that a VDI read-out can differ slightly, by one or two numbers + or -, when using a different size, shape or type of search coil. I do some urban Coin Hunting from time-to-time, but I devote the majority of my detecting to Relic Hunting older sites that usually abound in a lot of trash, especially nails and other discarded ferrous type junk. Thus 'target masking' is going to skew a lot of the good targets I am after so I am not looking for a rock-solid, dead-on accurate VDI read-out. I am, however, pleased when I get a reliable TID.

Because I hunt very trashy sites with a lot of rocks, brush and building rubble, I keep the small 'OOR' coil mounted to my FORS CoRe 90% of the time, opting for the standard 7X11 DD only when hunting a plowed field, a beach or some other very open and sparse-target location. Here are the VDI read-outs I get from an assortment of the US Coins I have found, and using my FORS CoRe and 'OOR' DD coil to check the read-outs. Coins positioned flat-to-the coil at a distance of about 2½"-4" :

67/68 .. Flying Eagle 1¢

80/82/83 .. An assortment of 11 Indian Head 1¢

80/82/83 .. An assortment of early 'Wheat-Back 1¢ from 1909 to 1920

82/83 .. Modern Zinc 1¢

84/85 .. An assortment of Wheat-Back 1¢ from 1940 to 1968

49/50/51 .. Nickel type 3¢ piece

54/56/57.. An assortment of Shield, 'V', Buffalo and Jefferson 5¢ coins, no including the 'silver' content "War Nickels"

58/59 .. An assortment of the 5¢ 'silver' War-Nickels

82/83 .. An assortment of silver Seated Liberty Half-Dimes

85 .. Modern 'clad' 10¢

85/86 .. An assortment of silver Seated Liberty, Barber, Mercury and Roosevelt 10¢

88/89 .. Modern 'clad' 25¢

87/88/90/91/92 .. Several silver Seated Liberty, Barber and Washington 25¢

93 .. Modern 'clad' 50¢

90/91/93/94 .. Several silver Seated Liberty, Walking Liberty and Franklin 50¢

88/89 .. Modern smaller-size $1

94/95/96 .. A half-dozen silver Morgan and Peace $1

So far the pennies seem to be ringing in around 83 and I think a quarter rang in around an 86 or 89 I can't remember exactly. I know there is no substitute for getting out and really learning the machine and digging the good tones, but comparing the numbers to what I think is in the ground is half the fun to me. And having an idea of what number goes with what coin would be a tremendous help. Thanks and Happy Hunting

With the FORS CoRe and Gold, with the more condensed non-ferrous TID range, there will be more coins and other small artifacts with close conductivity levels that fall in the ± '82' VDI range. You are correct, and the best way to know what results to anticipate is by getting out and using the detector more to learn 'results' first-hand.

Best of success with a versatile detector, and I hope my time and effort above was of some help.

Thanks monte. I always enjoy you're replys. You always address every point and I appreciate that. This is exactly what I was looking for. Thanks again.

I get confused a lot, I hunt for nuggets, but everything under the sun will turn up, bullets, casings , 22 cases are in the same range as larger nuggets.I think the Fors Gold+ is better at relics and coins than gold.I dig anything that rings higher than 50
I laminated this and keep it in my wallet.

Gold Ring 83 bronze 92
Small Nugget 46-47 Penny 83
half dollar 94 larger nugget 51-52
Dime 82 copper token 95
iron 5-25 Silver dime 86
Quarter 92 foil 45-50
Nickle 56 bottle caps 78-82
pull tabs 55-60
