do you get a LOT of bouncing around type signals where it will jump back from pulltab, to penny, to quarter then back and forth again, and the depth meter will go nuts up and down 2 inches, 6 inches 8 inches etc......

It seems like everyone of these type signals are near impossible to pinpoint as well, I dug a lot of them today and everyone was aluminum shreds, pulltabs or a bottle screw cap.

But everytime it is a coin it locks on and pinpoints almost perfect.

My question is do I just ignore these signals? Because today I had them all day long on the lot I was at, maybe I need a sniper coil for this lot. Ideas, comments?

I find that it either means you have the sensitivity too high or to low. I also found out today that it could also mean that there is multiple coins under the coil. I would start digging and find a coin, then sweep and dig again, and bam, another coin. I had one like that today that wound up having 1 penny, 1 nickle, 1 dime, and 1 quarter. I am messing with the sensitivity all the time, if the signal bounces I will lower the sen. and if the 2 rings are too wide, I turn up the sen. until I can get a fix on it. I have yet to find a location where I can leave that darn button alone.

and everywhere around here is too trashy, I usuially keep it around 2 bars, but it increases and decreases depending on the target.

 

[Goes4ever]

well that is just it, when it bounces all over I cannot pinpoint and when I try to dig it was trash everytime, even though it was bouncing in the coin range??

sensitivity was on the factory setting of 3 bars, I tried 4 bars at first at it was even worse

I will keep checking back, because I have had to move on to other targets more than a few times when this happens. I also hate it when youget a dollar signal, only to findout its a coke can. and have you ever had a target that keeps getting deeper. I dig and I dig and it will go from 4 inches to 6 to 8, then I move on...

since (1) got the Minelab and (2) it still snow covered up here :sad: but will watch the thread as I might learn something.

I don't own a Ace 250...but I'd say what your describing is probably something experienced across the board among the different brands to some degree. I use a White's and over the years I've notice the same sort of thing. In my case...when you swung the detector one direction it would kinda bounce up to around a quarter...and then when you swung the other direction...it would swing to the junk area like iron...or around the nickel area. As you crossed over the target from different directions the meter would just be all over the place! It jump from quarter...to...junk. At first, since they usually registered several inches deep, I though to myself..."There "Might" be a Silver Quarter down there by a piece of junk!?" But! when I dug it...it was a rusty, crusty bottle cap! Every time I'd get that signal...I tended to think the same thing...especially in an old yard! Probably a crusty bottle cap...But! it could be a Silv....well! lets put it this way....all I ever found was crusty bottle caps! Now! I've learned! If I get that type of response in an old yard...I "Might" dig 1 or 2 just to see what it is...if it's junk, and I get it again....I just move on! I've found that, that type of response is "Usually" what you get when a detector is trying to do its job...and discriminate out a junk target! And that Usually being small rusted up pieses of Iron! As you get into the higher end detectors, this will be less of a problem...but! you will still get some funky responses sometimes to real rust crusty iron...I mean the type where the Iron is not really Iron anymore...it's just RUST!

[size=medium]As Uncle Willy will tell you, practice! I would suggest a carefully planted and recorded test garden using everything you would most likely encounter. Make one area trashy, one with maybe a pulltab over a coin, a coin on edge and flat, and be sure to record the depth of each "plant" using multiple depths. It will probably help! [/size]
