My metal detector is sending me mixed signals! One minute it sniffs coins then a bit of digging changes the tone to iron (or rust mainly) is it to sensitive or just the ground conditions?

Its pretty accurate when it discriminates but its the confusing mixed signals. If I dig everything will I not just end up with a pocket full of rusty scrap?
Basically yes you loose depth. But using too much power on certain grounds can work against you in getting a clearer signal on some good targets. The best way to explain it that I didn't come up with is related to your vehicles headlights. Think of fog as the mineralization and trash in the ground. You running your brights but can't see very far because of the glare. You switch to low beams and although you can't see too far you can see better. So reducing your power on your machine can help in certain ground.Total newbie question then, does sensitivity effect depth? Ive popped it onto 2 after a dodgy signal and then get no signal.....

Machine is blind. See,s better than you or I though. Big iron a big find for unit even with iron discriminated out. (Though a couple notches enough to discrim little iron usually enough).That low iron tone and icon illuminating will still happen, just keep swinging and imagine the machine is just talking to itself, hmm, iron, nope .o.k. next, ha piece off foil , iron again, wait hint of copper, iron, nickle/pull tab gold, ding!,ding! ding! I,m a pin ball machine,(dig!).. Raising coil above target found will stop tone on a small target but a large one, maybe coffee can will keep ringing bell tone when you are a foot, maybe higher even above it. A handheld pin pointer will help solve some mysteries, o.k. it will help solve alot of mysteries.My 150 and I really got along different when adding a pinpointer and discovering the little tiny things it could find that I was missing when digging. (the disappearing signals I had claimed.)
Multiple targets are common in same spot. That will confuse the machine and the user. Its a good thing when you have multiple tones over a small area and that high toned bell is just able to be triggered. You,ll see. A big solid hit can be a nice coin,or a can. In time it can be sorted better before digging, but if any doubt dig to learn more!
Its all new to me so im absorbing all of this info. You lot are really helpful thanks. Just another query, if for example the target was 3" deep im assuming if the coil was snug on the ground the depth would read as 3". If the coil was 3" above ground it would or should read as 6"? Reason I ask is I cant get very low on the particular field im scanning as the furrows are very deep.
I usually wait 'till after a good toad strangler (that would be a hard rain, ha ha.) to dig the iffy signals. After a good rain the digging is easy so I turn up the sensitivity because you can pop out the junk a lot faster and then move on quickly..If the ground is dry like concrete, I set my sensitivity low and just go for a cladfest, and maybe a shallow silver ring or coin.
