Got me a CZ-7

Steve,
Nice. All of the CZs are great detectors. Coin magnets. Great nickel window.
My advice to get the most:
1. Read the manual well...especially the part about ground balancing.
2. CZs have a sweet tooth for iron, and will false, especially in damp ground. You'll need to learn to hear it trying to fool you.
I like to turn on (un-notch) the iron tones to help with that, and of course, swing at good signals from different/right angles to check the signal quality.
As with most detectors, it it's falsing on a rusty nail, it will typically be falsing on the nail tip...but will pinpoint on the nail body which may be a few inches off.
3. That 10.5" coil is a secret weapon. As well as going deep, it will see dimes on edge as well as any coil made. It is heavier though: If you use it, be sure to adjust the pole length to allow the coil to just miss your feet.
(otherwise the detector won't hang from your arm, and holding it all up all day will hurt your arm/shoulder/back)
*Note: that because it does see coins on edge better than most coils, the 10.5 will often have the target in the side of the hole. Be careful when digging to allow for this to prevent scratching.
Coins on edge will pinpoint quite a bit off with any coil that can see them, as the coil is getting the biggest hit off the greatest surface area.
You can see this by just playing around air testing with a coin at different angles and 'depths'.
4. The pinpoint depth meter is 'adequate'. It's not as accurate as a Minelab but does give you a rough idea.
Listen for those short, repeatable, quiet, 'blip' high tones and dig some deep coins.
(And if you have the patience, and want to find an occasional gold ring, dig the foil tones as well.)
And don't forget to have fun.

I had a CZ 7a and it was the best CZ I ever had in iron. I don't know why ,But it was as a lot of silver coins I dug with it there was a nail in the same hole? It wasn't as deep as my CZ-3D though,But it was a lot smoother at the 4 sen. setting, 4 volume, and 0 disc. Then listen for the softer deeper repeatable tones. I think you will like it SKI. It does have a slow constant Battery drain that the 7a doen't and a little slower pinpoint,But it is really nothin' once you get used to it. And the battery life is something like 90 hrs. so the drain is no biggie.

Steve I just bought a CZ3D and I have had a hard time first understanding it too but then it clicked in what tone to be listening to and then a 10k class ring and 3 silvers showed up during a hunt. Keep that machine.
SkiWhiz,
Good to see you here. I don't remember if you had a CZ before or not ... mind is first thing to go!
I'm glad Harold,ILL brought up about the battery drain. I thought that was a CZ7 feature, fixed in the 7A, but again, memory is not perfect.
Lots of good advise posted above, from some people with decades of experience. Hope to see you here for a while.

It's a great machine............ Learn how to tell deep nails from good targets, and you will be very pleased.. Your nickel count is about to go way up.. Rings too..
Just remember you will dig some nails..but you will also dig some deeper silver...
If it is a CZ7..and not a 7A ..keep an eye on your battery.. It is still draining when off. I can't remember why that was..It didn't affect the machine operation though...other than lowering the battery power..

Thanks everyone. I know that it uses battery when turned off to retain memory and that it takes about a second for the pinpoint to kick in but neither will bother me. I am sure that the 10.5 inch coil is deep but I would rather use the stock 8 inch coil and trade the bigger coil for a 5 inch coil. I do have it listed to trade for the small coil but no takers yet, I may have to sell it and buy the 5 incher.
