Type 3:Force Scale

Features: 
This deluxe aluminium bodied gauge accurately reads Stylus Tracking Force to an accuracy of 0.002 grams, the finest reading available. 
Setting correct Vertical Tracking Force is absolutely essential for optimal record playback. Track too heavy, the music becomes thick and sluggish - too light and the sound will be thin and anaemic...the cartridge is also more likely to mis-track. 
The Stylus Force Gauge offers full metal casing, a backlit display, uses AAA batteries, and comes in a deluxe leather-look storage case. A mini screwdriver and a calibration weight are also included. 
Mechanical stylus balances cannot compete with the accuracy of a digital stylus force gauge and this is one case where digital makes more sense when it comes to fine-tuning your turntable.
