Fisher CZ 5 meter question

[Northwoods guy]

I tried out my new CZ 5 for the first time today , and was a little confused by the meter function.The manual says it will lock on to a signal, and if "iffy" may bounce between two ID's. It didn't say how long it would lock on, or how to unlock it. The ground is frozen, so I was marking signal locations in the snow and moving along. It seemed like the meter would stay locked for a long time. Eventually it would release, but it didn't seem consistent. I can't find anything in the manual on this one, so i will turn to you fine foks. Is there a set time the meter will lock on an ID, and is there a way to quickly release the reading? Thanks

Once it IDs a target, thats where it stays until you get another signal. And its true that the iffy signals will bounce between two IDs. I usually lower my discrimination to see if its the lower one. Nails give me fits! it'll bounce between "iron" and "Good coin", the two oppsite ends of the spectrum. I drop down to the lowest disc setting, without being in all metal mode, to see if the iron signal wins out.

As a general rule, those "iffy" signals are junk, but not all the time. Spend some time digging all of them, and you will learn the subtle variation in the sounds they make. I know right now the sounds all sound alike, but in time you will distinguish between a quarter and a bottlecap by sound more than by meter.

Thanks for the info. The meter makes more sense now. The beeps, crackles, and hums will take awhile to figure out. I will probably dig about everything until i start to get it. I dug a hunk of lava rock today that was reading above pull tab. I think it had copper ore in it.

I used to use a CZ5 and it worked good, but as for the Iron signals...
I noticed that it really gave a good signal when you had 2 nails (Iron) signals that were close together,
this would cause a high coin / low iron meter reading....
Once you start to dig, well it then stayes on High Coin until you got within striking distance of the target.

The CZ 5 meter is operating as designed. Two different targets close together cause the meter to jump around, even a difference in ground makeup. Try backing off the Sensitivity to see if that improves the readings. Learn to not rely on the meter as it confuses your ear.

Thanks for the advice. The comment on the CZ5 and nails was timely. I mostly gave up digging targets in this frozen ground. I have been wandering our land looking for high target areas. But I got this one consistent high coin tone target in an area with a lot of iron. I had to see. After much chiseling and dirt sifting I found it! A definitely antique "relic" 3/4 inch long square shank nail. I rechecked the hole and the was no other reading. I think a fine addition to my tool pouch will be a strong magnet. Northwoods guy
