help with ACE 250

[nolesfan7870]

I recently purchased a new ACE-250 and took it out for the first time last week. When searching for items it would seem to hit on something but when going back over the spot where the item should be it would not hit on the item again. Other times it would hit on everything, is this because my sensitivity level is too high, should I turn it down?

Thanks

Most likely you have it up too high. I rarely have mine above 5 bars. Usually 4 or 5 is a good setting. If i get a weak or inconsistant signal I will raise up the sensitivity and sweep over the area to see if it is a consistant beep.

I hope this helps!

Welcome to the forum.
What your detector is telling you, when it want pick up the signal on subsequent sweeps, is that it is a junk item. Coins have a regular shape to them so give off a consistent signal. A bit of foil or twisted bit of metal (often bits of aluminium cans) will scatter the signal that the detector puts out. This will result in you hearing no return signal or having a reading on the metre that is bouncing all over the place. Something else that can cause you to get a signal from 1 direction and not the other, will be a bit of iron or something else that you have told your detector not to hear. In this case, just sweep the spot from a different angle. This will clear up what it is.
As a general rule, you are looking for signal that will lock onto a notch or bounce to the next notch. It could still be a bit of junk, but as you get used to the machine, you will start to figure some of these out when you pinpoint. Paying attention to pinpointing will help on some targets, but the bottom line is that will always going to dig trash. It's just part of the hobby. We all dig it, they're usually just not in the pictures.

Turn it down to four bars and leave it there until you've got about 100 hours on your detector, then you can play with it at higher settings. Garrett coils are ultra-sensitive. Make sure the lower part of your cable is snug as any movement by it will be picked up by the coil.
