CZ-21 Tones vs Finds

[cdv1]

I'm still trying to learn the new CZ-21 and using it as much as possible with the upcoming winter weather getting closer but today, just when I thought I might be knowing what I was doing, the machine played with my mind. My very first hit of the day was a sweet clean midtone, every direction I swung over it. Needless to say, I was excited and more so when I pulled out a nice silver colored ring....unfortunately is was Stainless but still a nice ring. Later on, I got a signal that sounded off as a midtone but on the backswing it hit with a high tone, then a low tone. I figured trash and almost didn't dig and up pops a tarnished 14k womens wedding band. It wasn't 2" deep in the sand, mainly because of the clay under the 2" of sand at this lake beach. So being so close to the surface, I'm curious, why wouldn't this ring hit at a clean midtone? This was wet sand, not under water.

Overall, I'm really staring to like this CZ. I've done well in local parks on clad with it and now have two 14k rings with it. It will pay for itself with the finds in time but I think I'll have to put it away for a few months now that winter is almost here. Hope I don't forget what I've learned so far by the time March gets here!

Pics of the hunt are posted in the beach forum.

Cliff, somewhere I saw a chart made by Fisher that showed the percentage of gold rings that sounded low, medium and high. I found a massive gold band that made high pitch, but most gold rings are mid range, and some sound low tone. I will try to find that chart.

Thanks Gleaner for looking for the chart.

I understand that they can hit as a low, med or high dependant on karat rating and physical size but I would have thought that being close to the surface, in wet sand, it would have hit solid as one tone not come in as a piece of trash that hits with a different sound coming at it from different angles.

Guess you just never know and to be sure. It was just the third time out with the CZ, I am still learning the machine.

Hey Cliff, the CZ's are great deep machines, but that does not always mean they will always ring up "true" in every circumstance. As you noted, the ring that read off was on the top of the clay base under the sand. Clay can introduce a lot of variables into the field of detection. Key to using the CZ's or any detector is knowing the ground you're working and how different objects read in that ground.

Had more than a few silver dimes ring up as lower-midtone targets, when on edge or in a bad ground mix. And as gleaner suggests gold jewelry comes up all over the target range. Best way to use the machine is to decide where you would place the cutoff depth on common junk at any given site, then dig everything deeper that gives a good pinpoint indication. You might exclude iron if you're not looking for a lot of targets that read in that category as well.

Make sure you check out those iron hits in certain locations. They can result in an old nail bed that might indicate there was a structure that would help you find say an old dwelling that you're looking for in some old woods or a field. Then you'd go to digging everything above iron if you're not relic hunting for instance.

Hey, nice finds on those rings!

hi Cliff,
I have been using a Fisher CZ-20 since 1998 and have noticed over time that your best bet is to dig all targets that give a mid or high tone on the beach. I usually run in 0 or sometimes 1 Discrimination and avoid the low tone (iron)....It does not mean that you won't get a mid or high tone that ends up still being iron, probably do to size or corrosion, but it betters your odds or digging mostly good targets...hope this helps....

Thanks Lowbatts and Tiggar, this was only the first time out that I decided not to dig all, relying on the tones to make my decisions. I was using Autotune and would switch over to 0 in Discriminate to hear the tone. IF it hit solid low, I didn't dig. That 14k small womens wedding band just bothered me for some reason. Sure glad I dug! Now, I want mother nature to give me another chance, I want to go back to see if the IRON signals I got were something other than iron. I'm afraid though my detecting is done since I'm tied up till years end and I'm sure the lake and beach will be frozen by then. If not, I'll go back to learn some more.

Appreciate the comments.

your welcome Cliff, any other questions please feel free to ask, that is why we are all here....to help each other....
ps: I forgot to mention the autotone mode then switching to discrim 0...that works very well also....keep it up & I hope the weather stays
warm for all of us.....
