THE BASICS OF METAL DETECTING

A hobby metal detector is intended for locating buried metal objects. When searching for metals, underground or on the surface, you have the following challenges and objectives:

1.Ignoring signals caused by ground minerals.

2.Ignoring signals caused by metal objects that you do not want to find, like pull-tabs.

3.Identifying a buried metal object before you dig it up.

4.Estimating the size and depth of objects, to facilitate digging them up.

5.Eliminating the effects of electromagnetic interference from other electronic devices.

Your Omega metal detector is designed with these things in mind.

1. Ground Minerals

All soils contain minerals. Signals from ground minerals can interfere with the signals from metal objects you want to find. All soils differ, and can differ greatly, in the type and amount of ground minerals present. You therefore want to “calibrate” the detector to the specific ground conditions where you are hunting. The detector incorporates both automated and manual ground-balancing features which will eliminate false signals from most types of soils. If you want to maximize the detector’s target identification accuracy and depth of detection, use the GROUND GRAB function to calibrate the detector to the ground where you are searching. See the section on GROUND GRAB for details.

2. Trash

If searching for coins, which will induce higher tone sounds, you want to ignore items like aluminum foil, nails, and pull-tabs. These undesirable items induce lower tones. You can listen to the sounds of all objects detected, and decide on what you want to dig up. Or you can eliminate unwanted metals from detection by using the DISCRIMINATION feature.

3. Identifying Buried Objects

When searching in the DISCRIMINATION mode, different objects induce different tones (high, medium, low, bass) and are classified on the display screen in different categories from left to right. A 2-digit numerical reading is also provided in the middle of the display for more precise target identification. The DISCRIMINATION mode requires motion: sweep the coil over the metal object.
