CZ - sensitivity

[Richmond_Relic]

I have a CZ 7aPro. What do most of you run the sensitivity on? I am hard pressed to increase it beyone 4. It seems like if it can be increased to 6, a lot more depth is gained.. At least on a bench test. Thanks..

i own a cz6a and i can run my sensetivity all the way up but dont really know about a cz7a.

Check the coil you should increase it at 6 or 7 with a 8 or 10 coil in va soil ...that is your not near power lines. good luck.

Some ground or area conditions just won't let you run it any higher.
It seems like with the CZ70 and CZ3D sens. parameters were changed and just won't get over 4...For instance using a CZ6A in a particuliar area could raise the Sens. to 6..7..8 with no problems but the CZ70 4 was tops same area and same operator..3 things come to mind...ground conditions, outside interference such as power lines or you have a late CZ7A pro with CZ70 pro sens. parameters as the CZ70 pro replaced the CZ7A pro...In any case raise your sensitivity as high as you can while keeping a stable unit and the differences stated above the CZ70 at sens of 4 got the same depth as the CZ6A at 6 to 8 sens. settings. Hope this explanation helps and after using a CZ6A actually thought my CZ70 was broke when I couldn't get the sens. over 4...Perhaps Fisher may explain it better, but this was learned in field operation and not a stable lab condition where most units are tested..
