CZ21 goes into pinpoint mode on its own.

[lookindown]

My CZ21 started randomly jumping into pinpoint mode today. I would have to tap the button 3 or 4 times to get it out...sometimes it wouldn't come out and I would have to turn the detector off to get it to come out. Sometimes it would jump immediately back in, 2 or 3 times in a row. Other times I could hunt 45 minutes to an hour before it acted up. I never used the pinpoint button after it started doing that. It ran the last hour with no problems and when I was done I tried the pinpoint button and it worked perfect every time, over and over. Anyone else had problems with their pin point on the CZ21?

Ive seen alot of switches go bad ive taken them apart and fixed them when they fail and sometimes i just grease them and them come back to life hope its just that for you it would be a cheap fix

 

[woof!]

CZ21 is a piezoelectronic switch, no mechanical moving parts.

Possibilities include:

1. flaky switch (I haven't heard of them failing before, but it's still a possibility).

2. something gone wrong (for example intermittent connection) in the circuitry associated with the switch.

3. electrical interference (for example from a nearby military radar installation).

If it fixes itself, problem solved. If the problem continues to crop up, esp. if in more than one location, it probably needs a trip back to the factory.

IF I WORK IN THE WAVES - HAVE HAD WATER HIT IT HARD AND GO ON - OTHER THAN THAT - I NEVER USE MINE EVER - I THINK ITS A WASTE OF TIME - I CAN PIN POINT WITH OUT IT - I WISH THEY WOULD MAKE THAT BUTTON AN ALL METAL TO ZERO ID SWITCH - SO YOU CAN HUNT IN ALL METAL - PUSH IT TO CHECK EACH TARGET IN TONE MODE INSTEAD OF CLICKING OVER TO CHECK - THAT I WOULD USE
I USE RTG SCOOP - AND GET MY TARGETS ON THE FIRST SCOOP EVERYTIME - WITHOUT USING THE PIN POINT - UNLESS REALLY FAINT AND DOWN OVER A FOOT - THEN IT TAKES A FEW SCOOPS
HOPE IT ALL WORKS OUT FOR YOU

That would be a great setup to be able to check targets with the push of a button while hunting in AM without having to turn a knob.
