Dan, I just came home from hunting with my CZ 70 pro and I am constantly amazed at how good this detector is. No silver today, but I did find 5 wheats from the 8 inch range. That is average for a CZ. I also got a very deep Buffalo nickle( 8 to 9 inches). I hunted a trashy park and there was so much trash that I couldn't use the pinpoint button, but had to do a super slow "X" to pick the coins from the trash. I would like to see a VDI range like you suggested and a trigger pinpoint switch. I don't need a ground track feature, but a quick ground balance button like the Coinstrike would be nice. I don't have any trouble ground balancing as I use the factory "Bob" method and it takes 30 seconds or so to adjust the volume, sens, and ID button. I hardly ever recheck my ground balance, but I take my time and get it perfect when I initially start up. I buy and sell many detectors, but the cz 70 will be mine for a long time. R.L.
