DrumDial DrumDial quickly and precisely tunes all drums by accurately measuring drumhead tension NOT tension rod torque. Tension rod torque can be used to tell you when you are over tightening a bolt to prevent thread damage, but is not accurate for drum tuning because of the difference in screw tolerances, plating, corrosion, and thread wear. You can eliminate these problems by using a DrumDial to measure drumhead tension directly from the drumhead, allowing you to precisely tune your drums faster and easier than ever before. **Storage Case is not included with this item. It is for Display Only** DrumDial Features: 1. Heavy weight base for "Superior Accuracy". 2. Adjustable Bezel for "Zeroing Out". 3. Bezel lock. 4. Tuning range memory markers. 5. "Edge Guide" for edge distance accuracy.
