Metal bolt on some detectors can wind up notching stuff out when you turn the detector on. CTX can get chatty in some black sand. You set it on the ground and cut it on it cures it. It's also why you are supposed to cut a detector on over clean ground
Edit. Buddy of mine inherited some old arse green Garrett. I think that beast will blow an AT Pros doors off
Way I do it is cut the detector on and hit a clean area. Then cut it off and back on again. I know some guys wont get metal anywhere near an Excalibur cutting it on. You cut it on by your car bumper your messing up
Just don't put that aluminum lower rod on your CTX. They're made out of carbon fiber for a reason. In saltwater you'd be detecting the detector

That carbon Fiber is amazing stuff. It will transmit a current, but safe to use on a metal detector
Graphite fishing pole will buzz in a fog by a power line. It will also kill you in an electric storm
You should hunt the girl's school with the new detector
