MultiPurpose Digital Magnetic Angle Finder Functionality and purpose: This digital magnetic angle finder is ideal for measuring angles, checking and adjusting to specific angles for bevel cuts from a table surface, and setting saw blades, tables, and fences with precision. Accurate measurements: Supports relative and absolute measurement conversion, angle and slope conversion. Provides precise readings with an accuracy of plus or minus 0.2 degrees and increments of 0.1 degrees. Magnetic base: Designed with a magnetic base and strong magnets to securely attach the level to saw blades, tables, and fences for stable, hands use. Easy to use: The tool uses three function buttons. Longpress ON/OFF to power the device on or off. Press HOLD to freeze the reading for easy viewing. Press ZERO to reset to zero for relative angle measurements. Why you need it: Delivers precise angle alignment for bevels and miters, improves setup speed, and enables reliable transfer of angles between tools with a secure magnetic attachment. Use scenarios: 1) Bevel cuts on a table saw: Attach to the blade or table and set the bevel angle accurately, then verify each cut. 2) Fence and table setup: Attach to a fence or router table fence to achieve precise alignment and repeatable cuts. 3) Relative angle transfer: Use ZERO to establish a reference angle and HOLD to lock readings while transferring angles between tools.
