The TM-60 not only lets you use the tuner and metronome simultaneously, but its display, which is approximately 1.3 times larger than the previous model, the TM-50, is easy to see even when placed on a music stand, and can now show both the tuner and metronome functions simultaneously. Not only does it eliminate the need to switch functions, but it's also useful for practicing wind instrument-specific techniques such as controlling the length of a note while maintaining its pitch, practicing vibrato by modulating the note in time with the tempo, and checking the pitch of chords while using a metronome. The larger display is backlit and has two brightness settings: soft and auto, making tuning comfortable even in dark situations like on a dark stage or in an orchestra pit. In addition, thorough circuit revisions have resulted in a battery life of 130 hours, approximately double that of the previous model, the TM-50 (when the tuner is in use and the backlight is off). Even during extended practice sessions or on stage, you won't have to worry about battery life.
