You have a great detector for the price. I too own an Ace 250 and do some coin shooting in tot lots but have mainly crossed over to relic hunting with it. It will tend to give you false readings at times. When you hit an aluminum target it will most of the time show a coin of some sort. Also if you hit a pocket spill of coins it will tend to jump around a bit because it is reading several different denominations of coinage in the same hole.
Bad metal vs Good metal- Not all bad metal is bad. It could be a valuable or historical item such as the firing mechanism to a flint lock fire arm or a Civil War era bayonet or sword, depending on where you are hunting. Right now Myself and 2 hunting are are searching for a cache of around 2500 Confederate swords that are rumored to have been buried to prevent capture by the Union army. These sword would have a collector value of around $15,000 each even in rough condition. They would more than likely show up as Iron on the 250. So I always hunt in all metal mode and dig every target. Just remember these 3 words......Patience...Persistence...Perseverance
