I have the ACE250 and noticed that I will get two tones on the aluminum cans. One tone for the end where the aluminum is thicker and one for the middle part. I suppose I could be missing some valuable relic with this method but it did not take me to long to decided not to dig when I get those two tones.

Not too many relics would be made of aluminum would they? Aluminum rings up with the loud belltone on my detector. Iron or steel comes in with a much lower pitched tone and is more likely to be a relic. Now brass or copper might come in as a penny icon or even on up to the silver range, but it won't be shown as a coin unless it is very small..... or at least it does on my detector. I guess what it comes down to as we have heard many times, dig everything if you're not sure. Monty

A true All-metal mode will pick up the ground noise, which a person (given that the detector has the option) then adjusts out with the GB, or ground tracking takes care of it. SAT can do a bit, but is a poor alternative. If a person didn't GB, the ground noise could very well overwhelm the target signal(s). ..Willy.

Then I will have to learn to GB better..
Even when in "Zero" mode I have trouble with hot rocks..So I will have to learn to GB.

Actually, even with a spot on GB, there will be problems with hot rocks 'cause they're basically discontinuity's in the ground signal. ...Willy.
