I used to own a Fisher CZ 5 years ago...............I liked the depth but it was not very good in trashy parks. Ran targets together.....and I didn't like the idea of hunting sports fields with a 5" coil. Now I have the Omega 8000...........really liking it. But I wonder , what is the depth capability of the Omega compared .....to the CZ's??? One fellow I spoke with thinks that the CZ's run an all metal frequency and attach a disc to it to give the great depth. The disc falls short of the all metal hence.... all the deep nails. He says that the old Compass Relic Magnum 7 was the precursor to the CZ's....electronically speaking. Found this interesting.......what do you guys think? Maybe Monte or some of the other old hands would know...........I never had the chance to use a Relic Magnum 7. That aside what about the Omega depth in relation to CZ's..............????
