A little late reading your original post. But in any case, here are some suggestions:
Run in the default settings until you get more used to the sounds and ID numbers.
I run with 3 tones. Low= ferrous, mid tone = nickels, foil, pull tabs, gold rings, some bottle caps, clad pennies, and high tones = all copper pennies, silver rings, silver coins, some bottle caps, large pieces of ferrous metal in the ground for a long period of time.
Always look to the FE meter. If you get a high tone and the FE meter is zero, chances are it may be a good target. Some bottle caps will ring as silver with low or no FE reading. One of the ways to eliminate bottle caps is to slowly raise the coil above the target. Usually, but not always, if the tone doesn't change to a lower tone, it's a good target, also, move the coil slowly back and forth over the target, if the tone doesn't change, it is usually a good target. The tones will not change if it is a true silver target. An exception to this is if the target is deep, say deeper than 7 or 8 inches.
If you get a high tone but it is a bit "iffie", that is it is mostly a high tone with intermittent mid tones, it may still be a good target. One way to further determine if it is a good target is to switch to ALL Metal Mode and then pin point the target. If it was a ferrous target giving the high tone, it will now be seen clearly as a ferrous target. Works almost every time for me.
Don't use the BP process all the time, especially in trashy areas. Using the BP process requires that you slow down your swing and it can produce lots of false signals. I use BP in non trashy areas and I use BP when I get a deep signal.
If you are going to use ALL Metal Mode, make sure you do a really good ground balancing. Make sure you are not ground balancing over any metal. Find a quiet piece of ground with no signals at all and ground balance over that piece of ground.
I use ALL Metal Mode in the woods when it is fairly junk free. You have to keep your eyes glued to the display as the sounds it gives you are worthless. The only sounds you get in All Metal Mode is louder if the target is close and less loud if the target is deeper. Pretty much worthless. And when you have your eyes glued to the display make sure you don't rap your head on branches or trip over stuff on the ground........as I've done numerous times.
Make sure your swings don't go in an upward ark. This can give false signals. Keep the coil parallel to the ground at all times.
There are times when I can determine that there is a legitimate target amongst garbage targets. This takes practice, lots of practice. Rotate around the target listening closely to how the tones change. Move the coil rapidly back and forth over the target in shoulder length strides. Pin point as you rotate around the target and see if any separating occurs. Switch to All Metal Mode and see if you can still see and hear a good target as you rotate around the target and again pin pointing often as you rotate is always a good idea.
Probably most important is to read the manual cover to cover. Go out and detect. Come home, read the manual cover to cover again. And so forth. Do this as often as you think you need to. After 4 years, I still read the manual to see what I forgot.
The F75 is a hot sports car. Run it slow until you get used to it and gradually increase its power. If you start out hot, you will get frustrated. The F75 will see EVERYTHING when you run it hot, which is what it is designed to do. It will overwhelm a new user.
I sometimes use notch filters. But not that often. Notching out foil and pull tabs for instance can also make you miss gold items. But if you are in an extremely pull tab laden area, sometimes you have to notch then out to save your sanity.
Some people say they dig all foil and pull tab targets, and likely these are the people who will get the most gold items. At my age, I have to be kind to my body, especially my back, so I cannot dig everything. I was in an area recently where pull tabs were every few inches. If I dug all those, I would have had to be airlifted by copter to the nearest urgent care LOL. But I do dig pull tabs, lots of them, but with a good deal of discernment. And....sometimes, it is a gold ring.
Good Luck, Have Fun...and don't get FRUSTRATED. After all, you are in the great out doors, with nature, getting great exercise Nothing is more pleasant than when I am deep in the woods, and I sit down on a log for a break and a drink of water and the peace and quiet is just overwhelming. I just love it. Or......I could just be laying on the couch watching re-runs of Gilligan's Island. I'll take the former any day.
