With Snap Check Pro's, precision machine setups are fast, easy and accurate. Snap Check pro has a large, easy to read dial indicator that measures up to 2 inches in three different scales; a 1/1000 of an inch scale, a 1/100 of an inch scale and a 1/64 of an inch scale. All scales are synchronized on the dial face. 

Snap Check Pro makes setting up table saws, routers and jointers precise and easy. Even setting the jointer knives is easy. 

To calibrate the Snap-Check Pro's use the fine adjustment knob. You will be able to set both scale needles to zero and then read your measurements in both decimal inch and fractional inch at the same time. Two moveable markers are present and can be set to record range of movement. This can be used in applications like measuring a saw blades parallelism to the fence. The solid machined aluminum body with strong base magnets provides a solid tool platform, leaving your hands free to make machine adjustments. The dial indicator head rotates a full 360-degrees making it easy to read during any setup operation. 3 anvil tips are included: a flat, an extended flat tip for stationary objects, plus a ball tip for moving objects. No batteries are needed.
