Metal detecting can be hard and grueling. As a hunter, you needed to be conscientious and observant of your very surroundings. It is a fact that all metal detectors, especially the land based ones to produce audio signals when they pass over metal targets. This sounds can be loud or even faint. With the external speakers built into metal detectors, these sounds can be misleading due to alot of factors. For one, if the target is small you will hear faint and deep signals.
With a headphone, you will hear even the faintest of sounds. This means additional find for you! Not only that, environmental factors can be blocked out. Howling wind, crushing waves and children laughing for example will be muted, leaving you out there “alone” with your metal detector.
In addition, with a headphone, you will be saving the life of your metal detector’s batteries. This is because the speaker in the detector is turned off when the headphone is plugged in to it and so, no energy is required to drive the detector’s external speaker.
