Discrimination question on the ace250.

[Mick in Dubbo]

Hi all
Finally got my hands on an Ace250 for the first time last week end.
A workmate seemed to catch the bug a couple of weeks ago and bought himself the Ace250.I took him out on a hunt and took him through the basics of how to run it.(What a doozy of a pinpoint mode, the best I've seen yet!).After putting a few coins on the ground and running the detector over it to show him what to expect with a good target,I noticed that the discrimination jumped around over a three notch area.I know the weather had a fair bit to do with that as my X-Terra30 was behaving in a similar fashion on our tree smallest coins but stable on the larger coins.We had about an inch of rain the day before and the humidity was at 70%, temp was a cool 15deg Celsius.The ground condition prior to this rain was very dry with virtually no moisture in the ground(only about 3inches all year).I set the Aces sensitivity to 50%.
The question that I have is, that under "normal" conditions does the ace lock on to a target within a signal notch, or does it bounce around (assuming that a target wouldn't be found to come up between two notches)
Thanks,
Mick Evans.

In ground targets will lock on unless there is another coin or junk close or the coins are crappy or corroded.

It usually locks on coins,but sometimes old wheat penny and a zinc penny will jump to dime range and back, i think the older the penny the closer to the dime range i would have to check,and mine says quarter it usually is or half dollar except if it is a washer my cans usually fall under dime.Also if you watch the depth gauge on a can when you swing over it climes up and down where over a coin it is usually pretty steady.hope this helps. Good luck and good hunting.
