Well I decided to buy another detector because the other one just didn't act right. The new one is about as simple as it gets to operate. Doesn't go very deep, but hey, most coins and rings aren't found that deep anyway. I'd say about 5" to 7" is it's limit on coins, but on larger objects maybe 10" deep. I found a piece of #4 copper wire 3" long at about 10". One thing I noticed today was I found very little aluminum trash the other detector just loved to find, regardless of what settings you had it on. It also found a few pennies which the other detector couldn't seem to find. Keep in mind I carefully went over the same area of ground that I had already been over with the other detector.
The new detector is so light (about 2.2 lbs) it feels like a toy but it works good for me and that's all I ever wanted. Something I could have confidence in if you know what I mean.
The new detector only has one tone. It's so simple a 4 year old could have a blast with it. You also hear the breaks in tone which i'm guessing it's all that trash aluminum I mentioned above. And it don't have an overload sound which I hated on the other machine.
I paid about $302.00 for the other machine tax included and only about $160.00 for the new one with no tax.
This is about 30 minutes worth and not on grounds you would find a lot of coins on. I think i'll be happy with this one for a long time.
