TARGET IDENTIFICATION continued
2-Digit Target Identification
The 2-digit value in the middle of the screen provides a specific target value to help identify buried targets more accurately. With practice in the field, you will learn to associate target values with specific objects. Coins are more likely to yield the same value with each pass of the coil due to their concentric shape. The presence of multiple targets will yield multiple tones. Trash objects are more likely to yield a different number on each pass. The angle of the coil relative to an object may also influence target identification. If waving coins over the searchcoil for practice, wave with the flat side parallel to the searchcoil; this is the position you will most often find coins buried in the ground.
