About AcousTech Electronic Stylus Force Gauge by Turntable Accessories:
The Deluxe AcousTech gauge is set apart from the standard version by a full metal casing, AAA battery support, and a deluxe storage case. Includes mini screwdriver and calibration weight.
The AcousTech gauge will accurately read your tracking force within 0.002 grams, the finest reading available. Many imitators only read accuracy of 0.01 grams.
Accurate and simple to use – that's the essence of a great stylus force gauge, and that's what you get with this AcousTech model. We all know, or certainly we all should know, that dialing in your correct tracking force is absolutely essential for optimal record playback. If you miss on the heavy side, your sound becomes thick and sluggish. Miss on the light side, and your cartridge is more likely to mistrack and the sound will be light and anemic.
So stop messing with those mechanical stylus balances that aren't even accurate. This is one case where digital makes more sense when it comes to fine-tuning your analog.
