Would Fast ON have made a difference on these two targets? I think so but did not test it.
Take a look at this first diagram, here you see two nails pointing towards two mind you, two silver quarters of all things. The nails were about 12 inches apart. Notice how the nails are casting an iron signal out along their length beyond the nail for several inches. This is how iron masks other targets.
Running all metal, zero discrimination I swept these two quarters from multiple angles and all I heard was silence, no iron tone, no threshold, nothing. Technically thats not supposed to happen in all metal right? How can the machine null when you are running zero discrimination? But it does, go figure. I have dug three of these (I call them all metal nulls) and was rewarded all three times. On this occasion with two silver washington quarters.
Here's another tough one that demonstrates just how powerful iron is at hiding nearby good targets. Again I was running all metal. I hit this target with just the front 3 inches of my coil and heard that sweet silver sound off. I moved forward slightly to center my coil over the target and poof it vanished, nothing but low iron tones. I backed up, the silver returned. I turned left, right, hit it from the top, nothing but iron tones. Went back to using just the tip of my coil and bingo good tone. I dig two silver quarters and a dime. I have dug MANY a large cent, other silver quarters, even a giant barber half dollar that I could only get a signal on from one narrow angle or the front part of my coil.
