This is the Intelli IMT-900 Auto Tuner, which is an upgrade to the IMT-500. The new IMT-900 model does everything that the older IMT-500 model does and has the addition of a transpose mode and other improvements on performance. For example, when the Bb Trumpet plays a C the note that comes out is a Bb. Using the new transpose mode, this tuner will allow the Bb pitch to register as a C making it an excellent choice also for brass and woodwind players! . The IMT-900 is a clip style tuner that picks up vibration directly from the instrument. It can be used on a noisy stage because it ignores distracting noise that can confuse other tuners. It attaches easily to any instrument and has an easy-to-read LCD meter that acts like an analog meter. The Backlit LCD panel illuminates making it easy to see in the dark. Some of the technical specs are: Calibrate from A = 430 to 449Hz with 1Hz step. Quadra flat tuning - no need to remove a capo to tune your guitar. Tuning range: 12-note full range chromatic, A2-B7. Tolerance: +/ 0.5 cents, uses Quartz Crystal. Clearly shows how sharp or flat you are in cents. Powers off after 3 minutes to save battery life. Power source: Coin battery 3volt (CR2032) (included). Overall Dimensions: 45x45x55.8mm, (body only 45x45x14mm). Weight: Approx. 50g (including battery)
