To tune your metal detector, adjust the settings based on where and what you are searching for. You can set the sensitivity (the depth at which you wish to search), the types of objects you wish to locate and the types of objects you wish to ignore. This can be a difficult process on some metal detectors, but Prospector metal detectors can be tuned with only a few button presses.
Turn on your Prospector metal detector.
Click the "All Metals" button, which is the default mode for the detector. Click the "+" or "-" buttons to increase or decrease, respectively, the maximum depth (measured in inches from the surface of the ground) at which you wish to search. This is referred to as the "sensitivity" of the metal detector. The current amount of inches at which the device is set is displayed on the LCD screen of the detector.
Press the "DISC" button to set the detector to "Discrimination" mode. Press the "+" or "-" buttons to adjust the discrimination mode settings, which will configure the detector to search for items according to the displayed icons on the screen. Icons that are displayed include several types of coins, a nail, a pull tab and a bottle cap. The detector will give a special audible signal (high or low) when the selected types of metallic object is detected.
Press the "NOTCH" button to enter "Notch" mode, which displays "NOTCH" on the LCD screen. Press the "+" or "-" buttons to select types of metallic objects to detect. Objects that are not selected are ignored completely or "notched." This mode will produce a low tone for iron or common metal objects, and a high tone for silver.
Set the Prospector metal detector upside-down on a plastic or wood table and remove any watches, rings or metallic jewellery from your hands. Do not turn off the device.
Pass a sample of the type of metallic object you wish to find at different distances from the metal detector to get a sample of the sensitivity and tones to listen for.
Adjust the sensitivity, discrimination and notch settings as needed to tune the Prospector metal detector.
Test the device again using the method in the previous step. Continue tuning the detector until it is configured to your satisfaction.
