Headphones
Most metal detectorists prefer to use headphones instead of the
detector's built-in speaker. Headphones help block out background noise
(such as wind) and make it easier to hear faint signals. Headphones with a
built-in volume control will allow you to adjust the sound volume to your
preference.
