D'Addario Planet Waves PW-CT-15 NS Micro Soundhole Tuner
Designed specifically for acoustic guitar, ukulele, and other acoustic instruments, the chromatic NS Micro Soundhole Tuner remains perfectly concealed within the instrument's soundhole for discreet tuning. The non-marring universal mounting clip allows stress-free installation, while the highly sensitive piezo transducer senses vibrations directly from the soundboard for fast and accurate tuning response. The bright, multi-color display allows easy viewing in any environment. It's so small, convenient, and accurate, you'll want one for every acoustic instrument you own!

I now have a few of these - brilliant. much better for altered (lower) tunings than headstock tuners.
At first I was a little confused as to its use but it was me having a blind spot and now I love it. However I use it on a ukulele and the spring clip that holds it to the sound hole was too slack, I unscrewed it bent it a little and now it’s very form.
Excellent product, well packaged, safely delivered
