Needing settings fof the F75 LTD

[rayoh]

I just purchesed the F75 LTD, and trying to find different settings for finding coins, so far I haven't found much.

While I am not running boost process ( bp ) program since mine is a standard model , I would run in BP , sensitivity is up to your ability to handle a chatty machine and what the location will allow i.e. EMI interference.
Disc. again up to you , though I myself run very little disc , and never above 18. Most times I run it at 5, 4 and below to 1 is a boosted feature ( you'll see what I mean in the field) . 5 and above is not .
Lastly is tone,a lot of the time I'll run 3 or 3H ( 3H is site dependent for me) and I like to play with Delta Pitch ( DP) from time to time .

As a side note 28-30 are almost always nickels 30-33 are tabs oh and gold rings , 58-61 zinc and from what I hear Indian head pennies , 69-75 are dimes and copper pennies and lastly quarter 79-81 , silver halves are 85-87.

Hope some of this helps, just remember the silver coins have to be there to be found my friend, finding wheaties are always a good sign that silver is around. You have a lot of machine there.

Good luck and stay safe,

When you say 'finding coins' do you mean old ones, or clad?

If I am hunting a typical trashy park, I run in de mode unless the grass is quite tall, then I go to the bp mode. I typically run disc of 4 when no emi issues. If there is emi chatter, then I move disc up if a frequency shift doesn't help. Usually around disc of 7 and sen of 70 or so works. Without emi, I run sen of around 85 and I prefer 3h and 4h tones. Good luck. HH jim tn

My F70, 11" DD coil, the little sister of the F75, I find my setting similar to yours -- Just adding my 2 cents for comparison -- I have hunted some really trashy and heavily hunted parks in my area, so I set my Sens at 50, and I find coins as deep as 6" ground level. Lakota, I find, on my F70 that gold hits at 22-24 solid, anything below that is foil -- my disc is set to the 18 level. Nickels are 28-31, solid, depending on ground or what is close by, it might bounce a little higher of lower, but will center on the 30 or higher 31. Pennies and dimes, like your level, sometimes a dime and its a penny sometimes it is a penny and it a dime, but not so often if it is a dime the readying is much steadier but those pennies, well, I dig them, just for that reason. Hit a silver mercury at about 5" and it was solid 72, not doubt, I thought it might be a Quarter on edge or a ring. Silver rings like good dime, Quarters in the high 70 ranges sometimes 80+ depending on the depth. Bottle caps are a nuisance but I am learning to read them, but they are elusive and I have yet to find a setting to eliminate them, so, I dig the &*^%$ things. I have had caps, depending on depth, how long and rust in the soil, etc. sound off as pennies, dimes and quarters. Used to drive me crazy but now I have tuned enough and found a trick or two to avoid most of them. If the soil is Cap rich I just have to dig them, when a Quarter hits there is no mistaking it, but the false bottle cap will lose its magic if you are patient and hover over the target a bit and the reading begins to become doubtful and there is this little reverb kind of sound, like a high pitched, metallic twangy sound off in the back ground as you leave the cap on pass over. It is ever so slight but if you can hear that, it is 99% a cap, if you can't hear that little "tell" then you gotta dig. Peace, and good hunting.

I'm also fairly new to the F75 SE/LTD and have found some great threads regarding settings using the search feature. The F75 is a hot machine and most make the mistake of trying to run the gain too high right off the bat. The audio can be overwhelming until you get used to the 75's language. I would suggest to run in DE mode, low sensitivity, and 2 tones for a bit. That was great advice for me and helped to reduce audio fatigue without compromising depth. Now I run in 4H, but still bump back and forth between DE and BP with sens. ranging from 50-99 depending on the area, and the trash. If you are looking for older coins, do your research and they will come. You have to be hunting where they were dropped!

Good huntin'

Hmmmmm give this a try safe point to start wether park or field. Je mode disc 6. Sensitive 70-75. Ground balance!!!! Is important. Also try 2f tones for a while easy to tell iron from nonferrous. Ifyou get noise emi. While holding the machine waist height. Change freq. I find 7 works for me in several local parks. Then if needed. Reduce sens. Give it a shot its a fantastic machine. If there are coins. You will find them. Good luck. HH. C t.

Dbax , I have read a lot of F series user findings and numbers for said items and noted that a lot of the number are close if not spot on to my experiences with the 75. And yup your right smaller gold ring do like the 22-24 numbers, had a ladies 10k white gold with 8 birth gems lock on at 24 this summer. Oh and I dig a ton of trash trying to scratch that yellow metal itch. But in many instances I don't mind the bottle caps ( screw on or beer caps) simply because I know once I have removed them I don't have them messing with me at later dates. But yeah after you dig enough you can kinda call them before you dig. A side note on that though is good targets can slide into the beer cap numbers and you just don't know till its in hand.

Still find myself not being able to recommend the 5" DD coil for our machines, especially for the 75 , awesome coil for those target rich yards and parks. Great depth and you can almost always run these machines hot as hell with little to no EMI problems. Last weekend was the first real problem being able to run the 5" over 70-75 Sens due to a power transformer being right next to the yard. Still pulled multiple silvers and a number of wheats for my effort and this was just my first go at it there.
