I have ruined a few bits already as probably everybody else has too.
You need a test before the actual probe for XYZ begins. Basically a continuity test.
So when I go into probe, and click start, first it asks for a continuity test once passed, it allows me to click again to start the probe. People can cheat but, it is a safe guard. I rather have the extra step then ruin a $30 to $100 bit.
