Using the discrimination feature on the Ace 250 is quite easy. After moving the cursor to one of the target identification notches, simply add or remove a notch to either accept or reject a type of target.
If you have been using your Garrett Ace 250 metal detector for a little while, then you have probably discovered that there is a nearly endless supply of junk to be found such as pulltabs, bottle caps, shredded cans, foil, nails and a bunch of other odds and ends. Finding a lot of junk and only a few coins can be very discouraging.
If you aren’t already using the Ace 250′s discrimination feature, then you will likely be tempted to notch out the junk signals and focus on the coins. If you are only looking for coins as well as silver jewelry, then this approach can work just fine.
If, however, you have caught the gold bug and are hoping to score a nice gold ring, then you will want to alter your perception of digging junk targets. As frustrating as it can be to dig junk, the unfortunate truth is that foil, pulltab and gold jewelry share the same target identification range due to similar conductivity and size. By using your Ace 250′s discrimination feature, you may be missing the gold.
Another problem with using the Ace 250 discrimination settings is that deeper targets are more difficult to identify and will often jump around. If the target is a deep coin that is bouncing between a dime and a notched out position, the tone can break up and sound like a bad target.
For this reason, I recommend that you use as little discrimination as possible and rely more on the general location of the target id. If the id cursor spends more time in the coin range or gold jewelry range then it is worth checking out. If the cursor spends more time in the iron range, then you may choose not to dig the signal.
It is important to remember that the target id can provide hints about a target, but that it is not always that accurate. Even the most expensive metal detectors’ TID programs can be fooled at times so it is best to view the TID reading as a probable guess rather than actual target.
