A) 360 degree adjustment. That mean it can be located on the headstock (front or back), on the banjo rim, on any acoustic instrument in any location.. and the display can be adjusted to a perfect upright angle.
B) Settings...Chromatic, Guitar, Banjo (yes, the only tuner w/this setting needed especially for beginning banjoists) violin/mandolin, soprano ukelele.
C) Large display of note and color change when string is in tune. Also when individual instrument settings are selected (not chromatic) it displays the string # being played.
D) Only 440 HZ.. No chance of pushing a wrong button and being tuned in a higher or lower pitch. In fact it only has one button. Plus it will stay on the instrument selection chosen when turned on and off
E) Automatic shut-off after 2 minute of non use.
F) Small, compact, and aesthetically designed. Plus, it may folded over and left on the instrument when put in the case.
G) Instructions written in simple sense by Wayne Rogers.. I explain things like string dampening and why sometimes you may have inaccurate readings (Like a badly worn string!)
