Very helpful for obtaining accurate (wireless) rpm data. Good thing too, my previous 'estimate-rpm-by-ear' method resulted in both idle and high speed settings that were smooth but much too high.

Nice to have a quantitative way of determining if a motor is reaching specified rpms. Listening works kinda, but being able to document precisely for future reference and comparison is great. Love the non-contact capability. Recommend!
