I give up

[oklahomabob]

I have a f70 and have tried all kinds of settings. I'm digging junk Will some on with the knowledge of setting up the f70 for old coin detectimg PLEASE tell me what settings you are using. I have found two mercury dimes, but it must have been just luck . With all the people on here someone must have a answer. Thanks, Bob in oklahoma

My F70 won't be here until early next week so I don't really have much information other than what is in my head from reading about it. All I really know is that it has a fast sweep speed (called Default) and a slow sweep speed (called Slow). In my mind...without having every held it in my hand...For old coin hunting...using the Fast Sweep speed I would set it up in 4 tone, gain around 75, threshold set to where it is stable, disc low enough to hear iron grunts, and recover the repeatable top, maybe top two tones or chirps or whatever they sound like at a fast sweep, even if there are other tones all around it. and pay no attention to the Visual Id. For Slow Sweep speed hunting I am thinking Delta Pitch audio, again with the gain around 75, threshold set where it would be stable, disc at 0, and go slow looking for higher tone, repeatable responses.

I would also think fast sweep means sweep "fast" and that slow sweep means sweep "slow". So sweep fast when in fast mode and sweep slow when in slow mode.

I would also think the more stable your setup the better your ability to hear the good stuff so don't be afraid to tune ether the threshold way down into the negative numbers.

Of course I could be totally out in left field because, like I said, I've never held one in my hands yet.

And digging junk is just part part of the process. Just make sure you are digging the right kind of junk

Good luck,
Mike

I takes a while to "click" with any machine. One thing that bears mentioning.....is that good targets tend to be smoother and "rounder" sounding. I know that might sound stupid.....................but its true. in time......you'll hear those subtle differences, unless your completely and utterly tone deaf. It just takes time in the field and practice. Mike kind of hit it on the head with his "diggin junk is part of the process". Trust me............we ALL dig junk!
Also......just because it aint a coin.,,,,,,,,,,,,,,that does not mean its "junk" I've dug a slew of real nice keepers that could have been junk............but turned out to be good stuff..........like gold...........silver ..and cool stuff like Tootsie toys and Roy Rogers rings. Truth is..............if you want to get all the goodies...................you have to dig all the signals.
Try to start out with relatively mild settings..............DE mode.........and maybe three tones. (4 tones if you hunt where you may dig older coinage). Keep it simple. Trust me..........it will come in time. Get out there as much as you can....and dig everything you can. VDI's Lie. The ONLY way you'll learn whats under the coil and what the machine is telling you....................is to dig everything........at least for a few months. I usually only dig colonial sites.............so tend to dig EVERYTHING anyway. It amazing what a lot of that "junk" is...........................

My brother has had a lot of detectors over the years and I don't think he has ever gotten one that wasn't broken (well believed to be broken LOL) and even sent a few back to just get a contact back saying they couldn't find anything wrong with the unit! He finely got a used Fisher 1270x that really was in need of repair. Now, when me or him gets a new (another) detector we make fun of "Getting through the BROKEN stage" There is some people that DON'T want to give up their old detector because of going through the learning curve (broken stage) of a new one, give it some time and you'll get it!

Do a factory reset by pushing and holding holding ground grab and menu button as you turn the machine on..hold em for a few seconds.."88" will appear on the screen, that will put your machine in a pretty stable all around settings mode...you can then thumb through the menu, and raise your disc to 15, and tones to 3 or 3h also you can push that "hz" button and it really stabilizes it out, even if you arn't getting emi..heck, you can run disc up to 55 and hunt in de mode with delta pitch, and all you will get are coins, and silver rings..oh sure, you may get one of those screw off bottle caps, and hotwheel cars, but they will only fool you once or twice...the F70 likes a medium/fast but even swing, and the furthur the arc the better, you can easily cover an 8' swath in open ground.
solid repeatables will make you happy, weird "bastard" signals are coin stacks, or tight spills.

I cant wait to hear what Hillis finds out when he gets his, as it will be a huge help to us all...I'm a newbie, but love this F70! Confidence in your machine is really crucial...tell yourself your gonna find what you seek, and believe it, and you will.

Many Many items will read the same as coins. A detector is only a set up parameter of most likely Id's on any given target.

The Processor knows what ..Say, a dime reads at. it will id that type hit as a dime. It could be many different types of items other than a dime too.
Same for lower id numbers Nickles Id will many many times be a pull tab..

Places you detect will make the difference in what you find. Old Homes .. = Old coins many times. New Tot Lots = new coins and other items just recently lost.

Research will take you to the right areas, practice will take you to the level of finding the sought after targets.......Junk is a given..You will dig it no matter what.

A solid hit may say more than an ID will about the target. Several variables can corrupt an ID, but they are still very helpful. I find it helps to print a copy of the ID #s and carry it with me. You have to remember they are guidelines/guestimates and not guarantees. Also check from 3 or 4 sides to see if there is consistency. Inconsistency may be from a coin on edge or angle so don't not dig solely on variation from angle. The wider the swing in ID the less likely the target is worth digging in my experience. Canslaw is a wildcard and can register anywhere and everywhere and is usually deeper and maybe off line more than anything else.
The F70 manual states:
The following table shows the numbers typically associated with certain commonly encountered nonferrous metal objects. Older silver U.S. coins usually read about the same as their modern clad equivalents. Modern quarter-sized dollar coins like the Susan B. Anthony and the Sacagawea read about the same as a quarter. Many Canadian coins are minted from a magnetic nickel alloy which gives very inconsistent readings and may register as iron. Most one-ounce silver bullion coins will fall into the same range as the modern U.S. $1 Eagle.
OBJECT TARGET I.D.
foil from gum wrapper 16-25
U.S. nickel (5

Hey Bob --

I have sent you a couple of PMs but not sure you can read/send them yet as a new user.

I am in Oklahoma and I have an F70. Send me an email at steveginger88 at hotmail dot com -- and we can chat...I'll see if I can help you out.

Steve

Take SGOSS66's offer. He put alot of effort into understanding the F-70.
