If you tap test a lot of tools, it will ease pressure on your back by being able to see the tap results in this Vufine viewfinder that attaches to your safety or prescription glasses. It connects to your computer with a HDMI cable and mirrors its screen. While the image is very small, it will clearly show under and over, as well as, double hits.
You can add hands-free voice commands to SpeedCast when running on Windows 10. For example, you can go through the Practice routine by saying "3" or "practice". Do the practice taps until alert is green and say "OK". Then say "4" or "measure" to start tapping the tool. Say "Coherence" or "Frequency FRF" to view accuracy of your measurements, the say "OK" to proceed to the next axis.
