Professional Metal Detectors

Professional metal detectors are distinguished by several features that make them more well-suited to serious detecting. One of the limitations of standard detectors is their inability to detect metal that is buried deeply. Another is the fact that the search is limited to the diameter of the coil. Pro models will use more sophisticated technology to give the treasure hunter a better range for finding good quality metal objects.

Professional Metal Detectors Give an Advantage

Some professional detectors generate a powerful electromagnetic field through the coil, which then flows into the ground. Highly conductive metals such as gold and non-ferrous objects will hold this current and transmit a reading back to the detector. This "pulse induction" method of metal detecting allows the operator to find objects at depths of up to 40 feet, much deeper than normally possible.

Another feature of professional metal detectors is advanced filtering that discriminates between desirable and unwanted targets. In most cases, the turn of a knob is all it takes to fine tune the search. A range of a half-mile is not unusual with units, and some can detect metal underwater or buried beneath several feet of snow. Magnetic locators can erase interference from items such as chain link fences and other metal objects that are near the search area.

The use of professional metal detectors can greatly improve the odds of finding gold and other valuable metals deep underground, where a lot of the truly good pieces are often buried. Advanced technology allows these units to give you a better range and ability to filter out unwanted feedback, thus making the hunt more efficient and productive. This gives the pro an advantage that can yield good returns over time.
