I think I found my favorite F70 settings...finally!

REVIER

Well-known member
I posted about this silver bracelet find in the Today's Find forum, this is about the settings I used in a usually difficult site to find it.


Well, after a successful first season hunting with the F70, more successful than I could have dreamed considering I spent so much time fiddling and messing around with so many settings and less time digging than usual, I think I finally settled on some that might just end up to be my everyday set up for most sites I hunt.
1 tone seems to be quieter, more informative, more productive, less mentally fatigueing and more fun for me to use than any others I have tried so far.
I used AM, 1F, 2F and 4H a lot this year, just a little time in with the others including DP...found a bunch of neat stuff, coins and silver and gold jewelry with most of them using 3 different coils, but 1 tone seems to work for me better in more sites with different conditions and all kinds of trash levels than any other.
You never know, I am such a big tweaker that I might even find better ones next season, but for now I am pretty confident and happy about this.

This year I learned with practice I could find great targets completely masked by an unbelievable amount of iron at an old farmhouse site using maxed out, blown out, blast through all metal settings, and when good finds slowed down to nothing I switched to 1 tone and immediately and fairly easily found more.
I hoped that this setting could work well in my normal park sites that are loaded with a large amounts of regular park trash and quickly found coins, silver and gold attempting to hide in those trash heaps so I found out it does.

2 days ago I tried this setting in another type of site that has its own share of difficulties and again it worked eye openly well.
This is a site that is in the woods, I have to trek up a small mountain to get there, because of the high location it is almost direct line of site of most tv, radio, and cell towers in the area so in many areas heavy EMI can be an issue.
This site also goes back to the late 1800's As a recreational horse trail site and camping area...now there are bicycle trails running all over the area.
I go there looking for old coins, they are few and far between in those huge multi acre area, but they are there.
I have found some 60's silver and a few older wheaties, others have found Indian Heads and Barbers and those are my ultimate goal.

I usually hunt this area in either all metal....very noisy but noise doesn't bother me all that much although it does tire me out listening to all that noise all the time, and 2F which is way quieter.
I read posts from users that said 2F is not bothered so much by EMI as other settings which is true, but 1 tone is even better I have found.

Also bothersome at this site is a decent amount of horseshoes and horseshoe nails buried here, among other horse related iron, and particularly
prevalent is tin and aluminum foil in all sizes left by campers over the years.
If you think that stuff breaks down over time you may be correct, but I am here to tell you it will take much more than 100 years before that will even to begin to happen.

This is what I tried for a short time here that day, and I can't wait to go back again.
Program 2 is set up as a second check over any good targets and in case I find something deep or any pop tops in the area.
I rim pop tops with the edge of the big DD coil and see the number drop way down usually into iron so I can recognize them and avoid them.
I look for areas with a decent amount of foil...an indication of a camping area, and then I switch to program 1 to hunt and look for coins.
Settings are 1 tone, sense way up to 89-90, disc at 25 to avoid most iron and most of the huge amount of foil pieces and I was able to get the threshold up to 2.
DE speed was very quiet, I switched to SL expecting much more chatter but again I was surprised with very little difference between that and DE so I left it there.
In this area with so much noise and falsing I got on all the other settings I have tried here, these settings were quiet...remarkably and jaw droppingly quiet as a matter of fact, something that surprised and totally pleased me to no end.
I searched each area this way and didn't find any coins this trip but I easily located and dug a few others when I came across each one as a solid and repeatable tone.
Some buttons, a piece of an old flashlight, a head stamp from the 20's, a couple of 22 cal. bullets a buckle from a piece of horse tack and a couple of pieces of larger foil that was not knocked out by my disc settings and similar targets.
I got some high tone falsing from some larger pieces of iron but I knew what it was because it didn't repeat like good targets did, one thing I did dig because it was so loud was this iron stirrup, my first from this site.
Plucking out these non ferrous and non foil targets was effortless and easy with these settings, much more so than I ever thought possible.
To do it so quietly with those settings set so high at this heavy EMI site was as I said, surprising and jaw dropping.

I was walking from one area to another looking for another camp site in disc and not all metal and came across another pretty solid repeating signal.
In the middle of nowhere really, but even though it was still a bit jumpy in the mid to high 60's it was still totally diggable at a site like this.
I dug down about 4-5" and found this small ID bracelet, I rooted around the hole with my Propinter and found that other small piece of chain, too.
No marks on this thing but it came up clean, left black marks on my cleaning cloth like silver always does, and it will be tested but I am 99.9% sure this is silver.
I am a jewelry hunter at my core, but it seems even at sites where I am looking for old coins 100% I guess if there is jewelry in the area I still have the skills and good luck to find it.
This small thing found in such a huge area just aimlessly wandering around is just amazing to me, maybe if some of those horse people or campers lost other silver or gold jewelry pieces I now have enough confidence that I have a good a shot as any to find it along with any of their lost coins.
Especially using the F70 and these 1 tone settings.
 
good write up revier for the most part i agree with your post my f75 is a chattering beast so run 1f tones to help with emi, i like 1f better than1 tones because i can tell how deep the target is by the modulated audio witch helps speed up target recovery good job on the silver braclet ive only been detecting for 5 years but i have learned you just never know where you might find something good my best find came from a grade school tot lot and it was a 10 gram 18k necklace hh

I used 1F and 2F here and other places in the past and it worked well.
I also like the added modulation.
However I did read a post from someone that contacted Fisher about some severe EMI problems he was having and Dave Johnson said in those areas try using 1 tone...no mention of 1F, 2F or any others.
This leads me to suspect that out of all the tone choices for some technical reason 1 tone might be the best and stablist to use in high EMI sites like this one.
 
Outstanding! :clapping:

I was in the red dirt of TN last Sunday with the 70...gb was 51...You know, I have not had the confidence of leaving the DP tones, mid sense, neg thresh for a few years now, so thats why I appreciate your results so much...I jumped straight from running AT to DP and have not once tried any other settings different...I believe it would take a Lifetime to delve into and master the optimum settings the 70 affords to maximize the varieties of a situation, and you are making a good run of it in short order and freely posting your experience with the thing for us to take advantage of..:beers:

I was running the big stock DD coil with a chain link fence on one side and some blacktop on the other in an area no wider than a standard swing, picking and pulling Q's to be danged, all sorts of trash as you can imagine, yet that 70 blows right on through it and locks on the coins...hit some parking areas and pulled more from the gravel, its just so tight and fast...NOBODY would attempt to hunt gravel unless they had a rig that put them right on top of the target in a tight profile like the 70 does...:thumbup:. (I eyeballed this little 14k earring in a parking garage)

As far as I'm concerned, no matter what rig or style, its RESULTS that matter...and you REVIER, (with your 70) get them..so thanks! :please:

Looking back, I have settled into running my weak settings and using coil manipulation tricks to overcome different soils and structure, I'll be hopping, highflying, and hovering coil in unconventional methods instead of using the available settings to my advantage, I dont know if I'll ever change settings, its taken me this long to learn the language of just these simple mid-power ones....I for one appreciate your diligence and path of F70 settings and discovery, keep it up brother! :clapping:

Thanks mud.
I will keep tweaking and experimenting at least a little till I can't anymore...that is just me.

You should step outside your comfort zone a bit and try a few other settings sometimes.
This year we got you to GB at least once in awhile so that is a start, I guess.

I now have a whole bag of tricks at my disposal to use as needed...if one doesn't work so great another just might...or 2 completely different set-ups might work equally well.
You just have to try them and see.

Just remember this...

The only reason I GB'd is I knew you would ask! :rofl:

Plus, it was one unstable chattering situation coming out of the deep soft loam soil of MI, where stabbing a target is easy....I gained an appreciation for what the Southern red dirt hunters have to deal with...some sort of God cursed red iron clay/chert amalgam that made stabbing tough and digging dang near impossible, especially in the limestone gravel parking areas, the only way to get a target out of there is with a screwdriver...good thing the soil was moist is all I can say..

That 'comfort zone' is a hard thing for me to overcome....Hey, I watched your vid on that sterling medallion!...that was a pretty cool pull in all that trash...well, I'm glad you take the time to try different settings/coils to make that 70 shine...I may need to join a local club and get some in field hands on regarding this 'optimum' settings topic, but now that the snow is falling hard and fast, I'll probably just continue to do what I do and bag coil and punch the clad munchkin on the ski hill on through to the Spring....

Hey R, did you ever get a chance to try to figure out by satellite image where I pulled off the road to hunt? It was off hwy 24 S of Nashville, Manchester specifically, you will see right away...very obvious, sportsfield and parks close to the exit...wish I had more time...somebody is high grading here, and I'm sure I missed gold..still, whoever it is hunting it is pretty danged good..so 'good job!' whoever you are if you are reading.:thumbup:

No doubt that 1f and 2f have helped with hunting in EMI prone areas. 1f has been my tone of choice with both coils. Hoping to send mine off soon for upgrade but haven't been in a rush with the new setting I have been using on my F75 LTD. Thanks for posting your results.
