Ace

Ace's are great but you need to do certain things to make them live up to their potential.

The cable from the coil to the display box needs to be tight and not loose. If it knocks against the pole on the end of a swing it will give a false beep. (took me a long time to find out about that one)
Do not swing more than about a foot per second or it will miss targets.
Have the coil about a foot above the ground when turning the unit on. This helps the unit calibrate itself.
Set the sensitivity no more than half way up the scale.
New pennies will show as dimes about 50% of the time. the older copper pennies will show as pennies. there is a difference in tone between a zincoln and a dime but you need practice and headphones to tell the difference.


Hope this helps

Congrats on your new toy Crash. Looks like a nice rig. My whites don't have a dime so the dimes read as copper pennies. I have had mine for only a month and still have a few things to figure out. Mine does the same thing with the beeping only once, but only if its an item that is discriminated against. I did notice that about it. If it hasn't been discriminated against it keeps on beeping. When I am around playground equipment I have to turn the sensitivity all the way down so I don't pick up the concrete footings. Well anyways good luck.
