A very small metronome... will fit in your pocket or any instrument case. Size: 2" x 3"x 1/4".
A display screen displays the tempo, a black dot that swings from side to side with the beat, and a display that will display the accenting of the beats on 2/4, 3/4, and 4/4.

Tempos can be chosen from 40 to 250 in one beat increments. The sound is a beep that can be turned off while the display shows the tempo

The metronome is held upright with a stand that swings out from the back. Italian tempo markings (allegro, moderato, etc.) are on the face. Battery (watch battery) is included, with an instruction sheet.
