I love my CZ21! I use mine on a belt as a waist mount setup primarily in freshwater lakes. I don't remember the last time I used the pinpoint mode. I've just used it so much that pinpointing is not an issue. I do ground balance but I have to agree with Casper, it doesn't really make a difference that I can tell for the hunting I do. I dig those "bell tones" because once again, the area I hunt produces more good targets than bad targets when I get a bell tone. I have no problem finding really small earrings, some are just an earring post and a non-metallic stud attached and I find them deep. I've really enjoyed my CZ21. Spend the time to master it like any detector and in my opinion you won't regret it.
