Korg CA-2 chromatic tuner
KORG's needle-style meter that shows you the pitch quickly and accurately now has a note name and string name display area that's approximately four times larger, making it easier than ever to read. Red and green LEDs to indicate the pitch discrepancy are also provided for even smoother tuning.
The CA-2 is a pocket-sized card-type tuner that's easy to carry anywhere. The rounded body is comfortable to hold in your hand, and now has an even more stylish design that accents the battery compartment. It uses a new mechanism that lets you replace the battery by sliding the entire body, so there's no risk of losing the battery compartment cover. - See more at: http://www.korg.com/us/products/tuners/ca_2/#sthash.WFHcMYeF.dpuf
