Blue Snark clip-on guitar tuner, cracked clip

I lost my blue Snark clip-on guitar tuner this afternoon around 3:15pm. It's palm-sized, about the width of a credit card, with a bright blue plastic shell and a small crack on the clip that attaches to the guitar headstock; the screen has a few faint scratches too. I think I had it outside the Wausau Center Mall on Wisconsin Avenue, near the main entrance by the food court after I stopped to tune my guitar. It was a gift from my guitar teacher and means a lot to me, I really need it back.
