RECOGNIZING FALSE SIGNALS IN DISCRIMINATION MODE
When operating in the Discrimination MODE, some "false signals" may be caused: 1) heavy
concentrations of trash metal objects, 2) very large trash metal objects or 3) electrical
interference. These signals are generally short, choppy sounds and sound different than "good
signals" (good target response sounds).
At the end of your sweep, as you reverse the coil direction, the detector is most susceptible to
trash-induced noise. There are two ways to tell whether these sounds are good deep signals or
trash "noise". The first is by repeatability. Trash-induced noises will not be regular as you
sweep the coil over the suspected target several times, whereas a good target response will
be repeatable. The second method is to switch to ALL METAL MODE and check the target
response sound. If the response is weak, it may well be a deep, good target. But if the
response is very strong, it is probably trash. Note that a coin close to the surface can give a
double beep sound, but it is regular and repeatable. Raising the coil an inch or two will restore
the single beep on surface targets.
When searching in the Discrimination MODE, it is best not to use a higher Discrimination Level
setting than necessary. Nickel and most smaller rings are rejected when the Discrimination
Level is set to reject pull tabs on any metal detector that is a TR Discriminator like the Outlaw. If
you don't dig any junk at all, you are surely passing up a lot of good finds as well. Set the
Discrimination Level only high enough to suit the conditions where you are searching. If there is
any doubt whether a target is good or not, dig it.
PERFORMING THE AUDIO BATTERY TEST
Your Outlaw is equipped with an automatic battery test circuit so you can always be sure you
are getting top performance from it. The battery should be checked after the detector has been
on for about 10 minutes and then periodically if you are using it for long periods.
