New Ace 250 user needs help.

[jamescpittman]

Just got back from a 45 minute treasure hunt with two grandsons at a near by playground and tennis court. Found about twenty bottle caps and no coins. Had to dig all of the caps up. Whew! I have the Ace 250 set on coins, with sensitivity at three from the left. Can't seem to dumb it down enough where it will eliminate bottle top signals. When it beeps it will show a penny or five cent or sometimes foil or pull tab. Can any one help me set my ace 250 correctly, or give me some advice on how I can recognize these annoying caps? I put a bottle cap on the ground and a nickel about 3 feet away and tried to adjust the machine where I could recognize the difference between the two beeps, but can't gat a good handle on this. Needless to say my two grandsons were disappointed that paw paw didn't find enough coins to buy ice cream. PS this was my third trip out since Christmas.. Did find several coins at a local college last week by my self.
Any constructive advice you can give will be well received.

Please tell how you have yours set up-sensitivity, mode, etc.

If the bottle caps are at all rusty, they become a nemesis.

I wil give it a try to give you some encouragement. I have used the Ace 250 for awhile now and do alright with it. A good amount of good stuff you want to find come up in the pull tab nickle area on your detector. If you notch out one pull tabs and bottle caps you will likely lose the nickle and other good things. Bottle caps come in many times where coins do. Also aluminum cans buried will sound off like something good. Do some informal practice with your new detector. Take some of the items you want to find coins and things you do not want to dig and do some air tests with your detector so you can hear the tones the detector puts through your headphones. In coins a quarter will make a nice chime like a door bell and most times show up on your detector display as a quarter. Iron, steel,nails, junk etc will make a different sound. Some describe it as a grunt sound. It will quickly become a sound your ignore. If your after coins using the coin mode it will chime on both pull tabs and bottle caps. Your sensitivity level was set a little low for what I use around here in my area. I'm usually running two lbars below the max on the right. I typically run higher sensitivity just below where the detector becomes unstable and sounds off falsely. When you find that your digging bottle caps you can notch them out by swinging over them and seeing where it indicates on your screen. Then go to your elim and discrim buttons and select that indication from the string and you will not detect bottle caps. See your. Manual on how to. Do. This. You will miss some good stuff but will spend less time digging junk. Play grounds are likely spots that other detectorist hunt and there may be fewer coins than you suspect. The other possibility is where in the play ground your hunting. Hunt under and around the equipment in the mulch. Swing your coil slowly and level and you should find coins. You may need to turn down your sensitivity when you get close to metal objects eliminate the metal and still detect coins. Some places just don't have much in the ground worth digging sometimes I have found something every few feet. Like many skilled hobbies practice and learning your machine will help you find the coins. Hope I helped the learning curve a little for you.
Detecting for fun and finding some coins is a good way to spend time with your grandsons. Find a coin under the coil and let them listen to the sound it makes and dig it up. You will have new hunting partners eager to go with you.

One thing.. Coins almost always are very stable when IDing in motion mode. They usually show the same over and over.
Often bottle caps will bounce around a bit as far as the ID. The more rust they have, generally the more they bounce from
high to low-med. Iron ID's fairly low on the scale. But rust is very conductive and will ID high. A lot of rust will usually ID pretty
high like it's a big coin. But... it will also bounce down low at times as it will also see the non rusted iron. So anyway, most
anything that bounces high-low will not be a coin. Sure there may be exceptions, but overall that will pan out most of the time.
Any bouncing high-low will usually indicate rusted iron. Roofing nails are bad about this when on the sides of houses..
Myself, I usually dig most anything unless I see a pattern. IE: if I get these on the side of a house, I'll get used to the ID and
start to ignore hits that bounce the same. But with single rusted iron hits, I usually dig it, as some stuff like that I like to find.
If a hit ID's in the coin range the same over and over, it's usually a coin. Some objects might mimic coins, but I dig all stable
hits just to make sure I'm not passing up something.

Sounds good to me.
