DISCRIMINATION POINTS

8.Some objects will cause sharp static or “ticking” when rejected. This is a perfectly normal response indicating that the powerful discrimination circuitry of the 1225-X is doing the job.

9.Large pieces of trash such as beer cans or jar lids may sound like a good target no matter what you do. With a little practice however, you will be able to tell the difference between a large target and a small coin-sized object.

10.The following chart shows some different target responses you may expect at different levels of discrimination. Note that as you increase the discrimination level, you progressively eliminate more targets including some good ones, such as nickels and gold rings.

Note: The discrimination levels shown are typical values only and may vary from detector to detector.
