The 11 inch isn't the sniper coil. The sniper coil is 5 inches. The F2 is now sold with different coil packages, so you may not have gotten a sniper. Trash is not a false signal. Gold comes up as trash. There is no such thing as a false signal unless you are detecting around electrical lines or high power lights. I think you just need to read more on how to work the F2. Make sure you have the sensitivity up to 5 bars and discriminate out the iron.

This is what I found this past weekend using my F2 and 5 inch coil. 106 coins plus jewelry. The F2 is a much better machine than the Bounty Hunter. You just had to learn how to use it.

I haven't had much of a chance to get out and detect. I am came down with some and have been feeling crappy. I will this weekend though! I will report back my findings.

Hope you're feeling better soon!

Hope you are feeling better soon. Let us know how your hunts go!

Went out hunting today. I got .17 cents over 2 hours. I am not to disappointed. The areas I am hunting are probably bare. Tomorrow I am going to try a different part of the park. The parks are pretty junky, lots of trashy metal. This thing is difficult to use when nothing is discriminating except iron. I do find myself discriminating everything out except dime and quarter, but that is only in the trashy areas. Tomorrow I am going to go with the sniper coil.

The best places to hunt are private properties. Ask your neighbors, relatives, coworkers, friends, etc... Any property older than 1950 (the older the better) has a fairly good chance of having at least one silver coin hidden in the ground. My experience is that most public parks are overly hunted; maybe not completely devoid of a good target but you'll have to work harder for the goodies. Good luck on your hunt tomorrow. The 4" coil is great in those trashy locations. Let us know how it works out for you. Happy hunting.

Try knocking out iron and turn the sense down if you are getting too many ghost signals because of heavy EMI or heavy trash.
Irregular shaped trash like can slaw and trash with holes like most tabs will definitely cause some very jumpy numbers and depth bars as you move different parts of the coil over them and even as you move the coil completely off the target.
The key to trash sites is to use the sniper coil if you have one, (if not...get one, they are very cheap to buy especially considering what they can find in trash), and no matter what coil you use go very slow when moving that coil so you can acquire and notice a good solid signal near trash.
I found this nickel right between two pieces of trash at these exact locations because I was going slow enough with the 8" coil to notice a solid 33 popping up as I moved the coil slowly over all 3 of these targets at the same time.
Target separation is excellent on the F2 at the right speeds...even better and easier with the sniper coil.

You lose about 1/4" in depth for every bar you take away and if you have good soil and can get 7-8" on a dime, or even a little less like 6" if your soil is not great, even if you go down to one bar you should still lose only about 1.5" from max depth at 7 bars and dealing with heavy trash sites will be a little easier to handle.
This should still put you at about 4.5-5.5 inches in depth in not great soil, (more in better soil), and well within range of mostly everything great I have ever found which is usually less than 5" in depth.

This bracelet was a zinc signal that was found on 5 bars instead of my usual 7.
Ghost signals don't bother me and I can usually pick out the good ones so I hunt on max sense.
This time I had accidentally turned it down and I still found the main part at 4" as a 64 zinc signal.
I rescanned and got an iffy foil signal still in the hole and dug down another inch and found that small piece of chain at 5" and foil...and chains are hard to pick up for any detector.



All of my best finds were below that dime and quarter only disc setting that you are using, chains of all kinds from foil to zinc, and especially the thing I am always looking for ...GOLD!
I have dug gold rings at 24, foil...35, high nickel, (but usually a sta-tab), 37-39, a genuine tab signal...42, tab and 3 large gold class rings and a slightly smaller wedding band all come in on the F2 from the mid 40's to the low 50's.
You will miss all of those at your current settings including every chain you ever come across, no matter what it is made of.

Here is a crappy movie I just made with my Galaxy phone about trash and the F2.
You are new and just learning so keep doing what you want to do the way you want to do it, however, dealing with trashy sites is a skill you will eventually need to learn or you will miss so many great things you would not believe it.

Well I got out and did about 3 hours of detecting with the F2. I used my 10 inch coil and found some good stuff. 3 wheat pennies, two from the 50's and one from 1916. I also found a 1928 Mercury Dime, my second silver. I also found a 16 gauge shell and a 44-40 shell. I also found some weird brass cap thing. I am not sure what it is. I am still getting the ghost signals and repeatable signals that I dig and find nothing. Should I decrease the sensitivity to decrease the ghost repeatable signals? I think I am getting the hang of the f2! Here is a picture.

when I've had those ghost signals I found it was a good item 6-8" to the side of iron. The iron combines with the target to throw off pinpointing. If I start to get a few of these I notch iron back in and usually you get a hit on iron close by. I've had to use pinpoint or different angles to eliminate this iron effect. It can do it really bad if the iron is just outside left or right of my sef coil. It can cause + overruns and flat out nulling detection as well. I discovered this with my lesche laying 18" away. Mostly see this come up when ground is very moist.

Note: this issue was much more evident with the SEF vs the 10". However the ground was as hard as concrete when I had the 10" so I'm not sure if its the same issue or this is just a SEF coil issue.
