7.Set your discrimination at an appropriate level. If there’s very little trash in the area, set it low, say at iron discrimination and dig every good signal. If there is a lot of trash present and you’re mainly interested in coins, set the discrimination level high—you may even want to sacrifice nickels and zinc pennies in extremely trashy areas. If you’re looking for gold rings, relics, artifacts, or small ancient coins, you’ll have to set your discrimination level low. The best way to find out how low is to bury some sample targets or just dig everything for awhile until you get a feel for which target classifications will be the most productive.

7.Set your discrimination at an appropriate level. If there’s very little trash in the area, set it low, say at iron discrimination and dig every good signal. If there is a lot of trash present and you’re mainly interested in coins, set the discrimination level high—you may even want to sacrifice nickels and zinc pennies in extremely trashy areas. If you’re looking for gold rings, relics, artifacts, or small ancient coins, you’ll have to set your discrimination level low. The best way to find out how low is to bury some sample targets or just dig everything for awhile until you get a feel for which target classifications will be the most productive.

8.Look for repeatable signals and don’t waste time on disappearing or one-way signals. If you hear a good beep but can’t repeat it when you go back over the target area, or if it beeps in only one sweep direction, it’s probably a piece of trash—something below your discrimination setting.

9.If you’re in a relatively non-trashy area, try searching in the Autotune mode and then identify your targets by switching to DISC = 0. You’ll find more and deeper targets this way.

10.If you’re having any difficulty pinpointing or identifying a target in the ID mode, don’t waste any more time. Push the pinpoint button for quick pinpointing then release it for accurate ID.

11.If your target disappears when you go into the Pinpoint mode, you’ve probably tuned it out by pressing the button too close to the target or over another piece of metal. Try again, this time pushing the PINPOINT button over another piece of ground.

12.Don’t waste a lot of time digging holes for targets you can’t find if your hole keeps getting deeper and wider, cover it up and go on. You may be over a buried pipe or some other large deep target.
