This rechargeable clip on tuner by Aroma is quite amazing. With one charge (via USB port - cable included), it will run for 10 hours. The detection range is from AO (27.5 hz) -C8 (4186.00 hz) - that's an astounding range.
The pitch will go from A430-450 so it covers 'low pitch' (aka early music) ranges.
Tuning accuracy is within 1/2 of one percent.
The metronome will go from 30bmpm-260bpm, with 'accent' beats available from 0-9.
It has a colorful screen display and is quite light (35grams).
