So I tried IM this morning...set it to -6 (explorer II with ferrous tones, using Audio 1). I had been using Coins preset with Audio 1 in Ferrous. It seems, when using IM, sounds are different (ie a clad dime sounds with more various tones and less high pitched). Also, pennies and nickels show in different locations on the screen. Why would this be? What is the advantage of IM? What is the optimum IM setting in trashy ground? Non trashy ground?
Thanks
The sounds are different in conductive and ferrous because that is all you are changing. That is what you selected off the menu. "sounds" to change to ferrous.
-6 is using very high discrimination. I think you want at least -10 if you have the basics of the detector down. I personally use -14 conductive and don't change whether the site is trashy or not. The idea is to get used to the highest sens. - lowest disc. you can run and the detector still makes sense and you do well. This is a gradual thing that takes time and if you were to use my detector in a trashy area it would probably sound like it was broken with all the noise. The reason it's better to stay with the same setting is once you've put the time in to reach that goal setting which works well (and high disc-low sens does when you know it well) there's not going to be a reason you'd want to change. When you REALLY know the detector it's almost like there's very fine line where the iron breaks through and when your ears are good and tuned to that setting you recognize very subtle differences above and below the line and that's what helps you dig more quality targets and leave junk (mostly iron) behind. I spent several years playing and adjusting to get the settings I am most happy with at my old sites in fields, and once there I never looked back. (nothing fancy, just what I tallked about in this post) I haven't changed a single setting in 5-6 years unless it was to deal with interference etc..
I didn't change from conduct. to ferrous. I have been using ferrous sounds for weeks. The only change was using IM. It seemed with this change alone that a clad dime sounded different....It was curious to me. Also, dimes, nickels, pennies were not showing on the same location with IM as with Smart mode. I will try changing IM to -10 and see if I can hack it. I am only starting to get comfortable with the explorer. I will note, that I found MORE quarters (clad) today then ever in IM...maybe a product of searching a different place, using IM, or a combo of the two.....
