I've been detecting some beaches that have renourshed sand pumped in. I'm guessing the mineralization might be somewhat different than the older "nature made" ones.
Anyhow if ground the loop, hit the pinpoint pad... ground bal on 10 I get some tone-level, adjusting the GB to 1 increases the tone level. Sort of like the ground bal wants to be higher than 10.

Any comments?

I HAVE NEVER GROUND BALANCED ANY OF MY CZs (I OWN 3 CZ21s)
I SET MY GROUND BALANCE ROUND 5 AND SENSITIVITY AS HIGH AS I CAN - IN NEW ENGLAND WATERS I CAN USUALLY DO ABOUT 9
I JUST TURN ON AND GO JUST MAKE SURE YOUR COIL IS GROUNDED AND NOT UP IN THE AIR
I DID THAT PUMP THING LONG AGO AND ENDED UP LOSING DEPTH
I USE MINE IN ALL METAL - AUTOTUNE 99% OF THE TIME
AND CHECK TARGETS BY CLICKING TO ZERO AND THEN BACK AND I DO QUITE WELL

Listen to Casper. I set mine on 10 and don't touch it. The key is the sensitivity. Hunt in all metal (autotune) and if you need to ground balance use that method.

Cool! Thanks for the tips there Casper and Adambomb. Today I tried hunting wet sand with wave water flowing across it and tons of high tone falseing using the "0" setting. It behaved ok using the all metal mode. I guess you could use a discriminating mode maybe the in dry sand if you had a ton of iron junk. We have one beach here full of sparkler wires and used "0" to wade through that. So Autotune it is. Don't mess with the GB, and sense up as possible. Getting to like this unit. Much easier than my Surf Dual Field with the low volume reference level and the wind and wave noise being a hassle.

Yeah, the method Casper uses is the tried and true way to use the unit. I'm down on Long Island and when hunting the Sound I set Autotune, GB of 5 and Sensitivity at 8. I see Casper says he can get his up to 9. I've tried 9 but I seem to get some falsing by me. I drop down to 8 (sometimes 7) and then my targets come in true. If my first few targets turn out to be junk, I will then check the rest by clicking to "0" otherwise I don't bother.

Good luck, looking forward to your finds posts! :)

Someone on here wrote a book on the 21. Good reference. The 21 is a great machine. Just don't drop it on its knobs on concrete like I did! Got the sakes waiting on the repair.
