On a banjo you have two G strings and two D strings. As the G (or D) string is plucked the other octave string will sympathetically vibrate causing the indicator on a normal tuner to "waver." On the BGT, the tuner will pick up only the fundamental of the string which is played, and the needle indicator will remain steady. This results in quicker and more accurate tuning. Available settings include chromatic,banjo,mandolin (fiddle) and guitar. Includes nice reusable tin for display and storage.
