Bandido ll uMax >>Setting Disc. using an actual target.<<

[ToddB64]

I want to set Discrimination on the Bandido ll uMax to just block out foil and below, but want to find targets with higher conductivity than foil, such as Nickels and on up the conductivity scale. Now, I've read that you can lay a target (that you wish to discriminate) on top of the ground and, by moving the coil back and forth over that target, adjust the Disc. knob until you no longer hear a response.

Now, as we all know, there are all kinds of foil, i.e. aluminium foil, tin foil, chewing gum foil, etc., and I would guess many different material compositions with varying conductivities are used, but still considered by the general public to be foil. Perhaps I could hunt until I find what I think is a piece of foil from the ground where I'm hunting and then use that as my test target to set discrimination by the method described above. Then, if I do dig another supposed piece of foil, but it looks different than the first, use it to re-set discrimination and so forth and so on, until I'm no longer digging foil. Is that the normal process with this type of knobs & toggles machine ?

Is there a certain type of foil that you all consider a good test sample for setting the discrimination by the method I described above ?

Your comments

Thanks.........Todd

Hi There
Bottom line you can disc out foils no problem,but the small gold rings /chains come very close to the foils range, why take the chance, you just have to dig.
Bet you would not Disc a Target that you can not disc out, this could be an old penny made of copper, in most cases worth knothing much, why disc out foil, this could be small gold ??.

I generally set my discrimination similar to Monte. Run the coil over a nickel until it begins to crack and fade than turn the knob back until I get a solid good hit on the nickel and go from there. I've marked the settings so that i can thumb the disc. knob up or down to help determine whether the target is under a nickel (foil etc.), nickel, tab, zinc penny, and copper penny or silver coin. Maybe not as slick as target ID, but works pretty well with practice.

I've found it just about impossible to completely disc out all foil. A clump of foil in a roundish shape makes a noise very much like deeper coin or a coin slightly on edge. It's possible my ear isn't all that advanced to know the difference but I sure don't feel comfortable that I'm being thorough without digging up some foil!

douglaskc ........I agree !

Guess it's entirely possible to become so intimate with your detector that you can tell various pull tabs & foils from gold jewelry by the tone if you hunt often enough. But for the average person who doesn't hunt that often and doesn't want to miss the gold, like myself, I recommend either All Metal mode and dig it all, or add just enough discrimination to barely knock out an iron nail as Monte said above.

I know I started this thread on the subject of using discrimination. That was because I'm trying to learn more about it (discrimination). But I really feel more comfortable using AM mode. I don't want to miss any valuable targets and don't mind the extra digging.
