This is a convenient tuner for the musician. I am a band director and it helps to have an electronic tuner around your neck or in your pocket. It can be a personal life saver on those days where everything is a bit crazy. It's not as informative as some bigger tuners with more dials and information screens. But, it is very compact and durable. You can take it anywhere. I also use it to figure out what key a song is in on the radio sometimes!
