CZ7a vs coinstrike
- Thread starter Eric
- Start date
Conventional CZ goes deeper and is user friendly while a Coinstrike is a faster unit with a number ID and a learning period..Might bring this up at a club meeting for discussion or talk to a Fisher dealer to try them on for size as both excellent units in their own right with the CZ being more popular as various models been around since 92 and only one model coinstrike I know of. Being a CZ guy I would opt for a CZ but have owned a coinstrike and once I got the hang of it got some nice silver coins but our area is loaded with rusty beer caps and had a tendency to call round rusty objects a coin. Of course the CZ does like those deep rusty nails but over the years I have learned to avoid them and dig very few. Bill Ladd has both and find they make a good combo from reading his posts..
I'm sure Dan is correct in his assessment, in his area. 
On the other hand I have yet to see a CZ go any deeper than a Coinstrike, and for sure the ID is not.
.
On the rusty caps, I say it's better to have them hit as a coin, because one can normally tell it is a cap, the ID numbers can be different, and one can tell it's not a coin when pin pointing with the C$. On the CZ's you will be digging real deep thinking it's a good target only to find a rusty nail head at 10".
Now all detectors have problems with rusty bottle caps at one time or another. Bottle caps are not iron, but comprise mostly of alloy steel, or aluminum. Of course it's the steel ones that rust. Deep buried iron like nails can be troublesome also. Ground mineralization plays a big part in how the detector reacts to it. The design engineers have a very narrow line to work with on both objects. Do you set up your circuit to ignore, or let it come threw because it could be a very deep good target.
Ending this post I want to say I have great respect for Dan & his opinion. When I first started out metal detecting he was of great help to me, and was perhaps the most lerned person they was on the Fisher CZ's. One other thing is that these are just opinions, and relate to the area we hunt in. Things can, and will be different for you in your area.
You all have a nice day

We all know Mr. Bill is a competent multi-line dealer and is quite talented with mods he has made to improve units and certainly respect his opinions..
I will go on record on saying coil for coil a properly tuned CZ is as deep as any on the market and deeper than most.
Let put it this way I learned how to avoid the majority of deep rusty nails with the CZ but the liking of round rusty objects by a Coinstrike I did not solve.
One fellow said they sound mushy when pinpointing and another said swing over it fast and it would go away and as far as going by an ID number which seems logical
they came dead on for a high coin so in reallity nothing worked.
It all comes down to 17 years experience with a CZ and several months experience with a Coinstrike and if it were opposite my answer might differ greatly.
Again both are excellent units in their own right in competent hands so take your pick and use what works for you in your area as many do well with either..

Here are a couple of videos I made of air tests on my old Fisher CZ7a. Hope they help you out:
