Metal Detecting Metal Detecting FAQ's Metal Detecting How To's Minelab Equinox Minelab Vanquish Metal Detector Relic Hunting
In this blog, I look at multi-frequency detectors comparing them to single-frequency detectors and offer my humble opinion of why the hype over multi-frequency detectors is overrated. For now.
A multi-frequency metal detector typically outputs 3 - 5 different frequencies simultaneously. In simple terms, the advantage means a target that is missed by a certain frequency might be picked up by the other remaining frequencies, thus increasing your chances of a find. However, when the detector sends multiple simultaneous frequencies, it requires a lot of processing, which comes at a performance cost, negatively impacting depth and reactivity.
Multi-frequency metal detectors are very good for beach detecting and use in saltwater. They tend to be more stable when compared to most single frequency detectors.
A good example of a multi-frequency metal detector is the popular Minelab Equinox 800, featuring a range of 5 frequencies: 5kHz, 10kHz, 15kHz,
