Thanks Charles and Dan.
Dan I haven't been detecting that long, I started in January of 2008, so under two years. I started off with a Coinstrike, struggled to learn it, probably was a bit much for a first machine. Unfortunately it didn't like EMI, and we have plenty of it around here, so I opted to try something different. Next went to a Fisher F4, then picked up a Minelab Sovereign for salt water beach hunting, and also used it for a bit of deep turf hunting with mixed results (doesn't like iron), then picked up a F5 which I liked, but didn't quite get the depth I was looking for. Then a Fisher F70, did real well with the F70 in the 6" and less range, but wasn't getting the depth I wanted. Next I tried an Omega. Nice machine, but not quite getting the depth. Somewhere in here I picked up an ID Edge, I do like this machine, still not sure on the depth but it seems to do OK, although not likely as deep as the CZ. Then I got the CZ70, it's a bit heavy compared to the new lightweights, BUT it goes deep. Soil and/or EMI seems to be a big handicap where I hunt, I believe the multifreq of the CZ70 helps it deal with the soil better then VLF machines, and it handles EMI a lot better. Also I think the big Sunray coil is helping, not only finding deeper targets, but it's a big help in ground coverage and seems to be sensitive to jewelery as well.
On one hand I shutter to think what I've missed not using the CZ70 as I've put hundreds of hours in using my small army of detectors, but on the other hand I'm making good finds at sites I've already hunted using the other machines with mediocre results, now I have several "new" hunting sports.
I agree, a next gen digital CZ would've probably been the pinnacle of CZ technology. I image it would have a 0-99 target VDI, lighter weight, retained multifreq, remained simple to operate, had a freq shift (good for hunting around other CZ users), kept the backlight, and with the new much faster (and cheaper) CPUs it would've been faster as well. Who knows what else. Now we have the F75 Ltd...I hope it's a deep seeker as advertised as I would like to get one, BUT it has to go deeper then my CZ70 in the same spots.
