Is there a difference between the two? I've seen detectors with just CZ70, and I've seen the other?
Reply... The CZ 70 and the CZ 70 Pro are both the same machine.
Some people just tend to leave out the word "pro" when refering to a CZ 70 Pro
Also will a CZ6 mount on a CZ70 Rod?
Reply... NO, neither will a CZ6a, CZ5 or a CZ3d
And would a CZ70 work better in mineralized ground than a Coinstrike?
The Coinstrike with its auto ground tracking is suppose to do better than the CZ 70 in mineralized soil. Both detectors go very deep and it is a toss-up as to which goes deeper.
In a heads up test I would put my $$$$$ on the CZ-70 Pro however.
The CZ 70 Pro would also beat out a CZ3d in a depth contest should one ever take place.
If you are going to hunt around power lines and hunt in big cities where there is alot of electrical interference then the Coin Strike is a very poor choice for a detector as it is easily effected by EI.
On the other hand Fisher CZ's are not effected much at all by EI and make for an excellent coin machine around power lines and in cities.
