Comparison
Other Imports
Other imports use a coil spring for tension. The coil spring arcs under oad binding on the fixture hole. As the coil loads and unloads it causes the movement to feel gritty due to coil bind and makes setting the indicator difficult and unpredictable.
Shars
New re-positioned spring stays linear throughout the travel eliminating spring bind. Adjustment screw uses a finer thread and ball shape at the end of the threads that sits in a pocket eliminating the screw from walking. This design gives the fine adjustment screw a positive footing, a more predictable adjustment and a silky smooth feel. The improvements minimize erratic dial hand movements and makes dialing in effortless, saving precious setup time.
