Target Identification – an Amazing Metal Detector Feature!

Did you know that today’s metal detectors actually TELL you what target is being signaled? When you first set out treasure hunting with a metal detector, you will notice the different sounds and tones your machine makes. You’ll hear low grunts and higher-pitched signals. Then, when you look at the LCD display on your detector, you’ll see numbers and/or bars illuminated on the screen. This is the Target Identification indicator. It indicates which type of metal is being transmitted. Usually, the target Identification has an iron section, a gold range and a silver range. Some indicators are extremely detailed, while others are more simplistic. It depends on the price of the model and how sophisticated the circuitry is. Target ID is important, because it can save you a lot of time before you start digging. If you’re hunting a trashy area, you may not want to spend hours digging up old nails and bottle caps.

Understanding Target ID Numbers

The numbers displayed on a detector’s screen give even more detail about your target. Target ID numbers are different per manufacturer and detector model. Your user’s manual will have a section explaining what the numbers are pinpointing. For example, on a Teknetics detector, the Target ID code of 88 likely represents a silver dime. Fisher “F” series models list dimes between 64-66. Whites detectors use ‘Visual Display Indication’ to represent targets. A U.S. quarter on a Whites detector has a VDI value of about 85.

As a beginner, it is important to dig up all targets your detector signals. You’ll then understand how your detector reacts to each type of metal. Later, you may choose to use Discrimination. Discrimination can eliminate trash targets: pull-tabs, foil and iron trash so you don’t even get a signal when trash is found. In fact, when hunting for jewelry at the beach, Daniel Bernzweig of says discriminate out iron plus coins at the top of the display screen. By Concentrating on the middle gold range, you up the chances of finding gold jewelryA whole new world of possibilities has been opened for new detectorists because of metal detector advancements – this includes entry-level models!
