I purchased this DrumDial Precision Drum Tuner new earlier this year from Chicago Drum Exchange and used it on a couple recording sessions. It is in like new condition, and comes with all the original documents, rim spacer clip, and packaging.  If you’ve been wanting a reliable, USA-made drum tuning tool that takes the frustration out of the process, this DrumDial is a solid pick. U.S. Buyers only, with shipping destinations within the United States.

From the manufacturer:
The DrumDial Precision Drum Tuner is one of those tools that every drummer ends up appreciating once they use it. Instead of relying on pitch matching or chasing tension by ear, the DrumDial measures actual drumhead pressure, which makes tuning faster, more consistent, and way more predictable. It’s incredibly useful for players who like to keep their kits dialed in the same way every time—whether you're maintaining a studio setup, prepping for live gigs, or just trying to get your drums sounding right without the guesswork. This unit works on both batter and resonant heads and is great for everything from snares to toms.
