Intellitouch PT10 Mini GuitarTuner
Clip-On Guitar Tuner

 

The Intellitouch PT10 "Mini" GuitarTuner is a small and compact, clip on  tuner with a large and easy to read display. It works by "feeling" (detecting) the vibrations of the instrument, when you play a note; then it displays the not on its easy to read screen. The display includes a needle that swings to let you know if your are tuning in the right or wrong direction, a large letter note with sharp and flat symbols, and a color changing background. The background is red when you are out of tune, and changes to green when you are in tune. It's calibrated from accuracy from 430 to 450 Hz. The controls are simple and easy to use, and it can stow in your instrument case or pocket. It also comes with a "no questions asked" Limited Lifetime Warranty.

 

It's designed to clip onto guitar, bass, banjo, mandolin headstocks, even violins and other bowed instruments. 

Note: The Intellitouch PT-10 replaces the PT-2, which has been discontinued.
