cz 70pro question?

[jdg58]

Is one serial number series any deeper than another on average or are they all about the same? I had heard higher numbers are deeper than the lower numbers.

Serial numbers have no difference in operation. They only indicate the run in production. Your statement is like saying one color car is faster than another color as all are made to specs.

Mine is 11 years old and it does as well as a new CZ3D..

Can you still get coils for the cz 70 and can you still get repairs on them ?

I have to quote another forum for this answer since there might be some difference between serials...:
"Roger was very nice to deal with...I have wondered on occasion where he is at this point in time. Here in Northern Ohio, we have deep, black, loamy soil I guess you might call it for the most part at old sites. The Coin$trike appears to go rather deep in this stuff. Is this the type of dirt you're referring to? I can almost predict the performance of a CZ-70 from it's serial number-the "hottest" from the factory I have found from all the different serial series start with 112. The earlier 102's usually like no more sensitivity than 4 before the ID starts to bounce and false more whereas the 112's allow a sensivity of 6 without the bouncing and a couple of more inches of depth versus a sensitivity of 4 unless they were factory re-tuned in my experience. The last CZ-70's produced in my opinion were pretty tame and somewhat sloppy in finishing on the control box. The 102 have the nicest fit and finishing of the control box whereas the 112's seem to have the faceplate peel in the lower corner by the headphone jack...the later serials often had crooked faceplate with some gapping around the sides in the front...just my observations over the years and opinions. The 3D's appear to be much more variable to me in their tuning from the factory. Some seem to be too sensitive, others have a smeared not sharp ID/sound at depth, some airtest rather poorly from right out of the box?..but in general the build quality appears to be consistently good. "


Hope this helps

Yes you can get coils for it, recently had mine checked out by Fisher, got a new coil, and some minor rework, however, Fisher is running low on parts for it and that was about six months ago. I noticed on some dealers the five inch coil is also available

That's good to hear...
