Wow! Yeah, you better 1F the whole site from orbit, its the only way to be sure.!

Good way to get the old ticker pounding I'll bet. Neat when that happens even though it turns out to be a false alarm at times. Amazing how awesome some cheap junk gold colored rings can look till you get the dirt dug out of them.
I realize there is a volume related to depth feature here but I'm curious though as to why there is a depth increase with the 1F tone choice. Does the VDI accuracy seem to be deeper also in 1F tone mode like it is in the Autotune mode?------IB

I think, and I am in information overload while I am trying to absorb rocket man Tom's posts about the F75 and deep hunting so don't quote me, but I believe it is not so much about going deeper but more about getting a more recognizable signal in monotone mode...definitely in one tone but I believe this is the same in 1F.
Since his disc was at 4 and not past 5 the smaller deeper items would not be changed to an iron tone like they would have at that higher disc setting and the other tone settings from 2F on up.

I think that is how it works, anyway.
Recently I have been getting away from my usual 4H coin and jewelry hunting mode and trying to get deeper targets and the 1F and 2F in more iron infested sites have been what I have been using.
I think I like 1F the most, one tone is ok but without that modulation I just get mentally fatigued quickly listening to that monotone for some reason.
Today is the last decent day we will have for awhile and I am going to take advantage of it and try to get back to the old park where I found that IH spill at 7-8" a few days ago.
I will hunt in 1 and 1F with settings as high as I can get them but disc still at 4 and look for targets that are 6" and deeper and see what I can find.
The wind should be less of a problem so I will experiment a little if I get some of these deeper signals and switch to the other tone settings and see exactly how clear and repeatable each one really is and that should give me some more info to base my hunting decisions on for the rest of the season...I hope.
I am having fun messing around with all my settings but I really want to determine the very best, deepest and clearest settings possible and have complete confidence in those settings so I can get to a site and set up and go without doing so much experimenting which does take away from digging and finding time, a little.

Where there are Indian Heads there could be Barbers and that is one of my goals for this year...a Barber of any kind, and I am hoping 1F will get me one and hopefully today.

I will report back on my findings later today.

Hopefully using the 1F tone in this situation will allow me to locate even deeper finds. The deeper the finds are located the less reliable your audio and visual target IDs are at IDing whats in the ground. So the chances of finding, let alone properly IDing any really deep and desirable target is somewhat less when using typical Audio and VDI settings. To what extent is anyone's guess.

This area were I'm using the 1F tone to hunt is pretty much clear of targets less than 5-6 inches in depth do to the many other TH'rs like myself that have previously hunted the site.

IBdiggen: At this time I can't say as to why 1F tones might offer more depth over the the other more common tone settings. I will say, in my personal coin garden the 1F tone was the only setting that would audibly indicate the presents of every one of my freshly buried coins/dimes.

I don't know if the VDI is more accurate while using either one of the 1 tones, not sure why one would be more accurate as both the Audio disc. and VDI work independent of one another as I understand it. While using 1F I was pretty much ignoring the screen info anyway except for target depth.

I wasn't aware that the F70s VDI accuracy improves while in Autotune mode. Hmmm? Why not have it accurate as possible in all modes?

I hope I said what I think I was saying.

Has anyone tried the frequency balancing thing that we were all talking about a while back? I think it was an F75 article on ground balancing and shifting through the freqs to find the cleanest sounding one to max out the depth.

I guess I should clarify a bit on my last statement when I stated that I thought the depth of the VDI accuracy is increased in autotone mode.
When I was learning the F70 I remember reading in the manual to ground balance in the autotone mode. I assign autotones as my default startup program 1 and then switch over to program 2 for my discrimination mode after ground balance is complete. I found myself starting to run higher sensativity in the program 1 in comparison to program 2 . I was learning how false signals differed from actual true signals. By switching back to program 1 with a much higher sensitivity setting I was able to identify more combinations of VDI numbers of medal present in the area not just the false simulations that you may be fooled into accepting as actual tones. It may be the VDI seemed, at the time, deeper to me in autotone because I am running more sensitivity there than program 2. But I will say sampling certain signals with autotones seems to be somewhat beneficial in unraveling combination signals such as coin spills and masking scenarios. Also works as a depth boost for those signals just out of reach for a VDI assignment. -------------HH--think spring thaw

This is the thread...

All was just copied from info rocket Tom has posted.

I have attempted to run through all the frequency settings at a few different sites to see if there is a big difference and so far it seems to me I get the same amount of noise on all of them so no big difference so far.
I haven't hunted next to any big power lines yet so I will try it there when I come across one.
There is one small, thin and longer park I hunt from time to time with several of these major lines running directly over the top of this place right down the middle and I wonder if this will help at that site.
I do remember at this park my F2 with the 8" coil was way noisier than using that same F2 and the sniper coil.
On the F2 the 10" and the 4" coil seems to be a little less bothered by EMI than the 8".
Come spring I will revisit this site with the F70 and see.

Although I didn't mention it in this post I did perform the frequency balancing step I believe your referring to just prior to switching to 1F tones. Below is a link to some info provided by REVIER were it mentions how choosing the correct/quietest frequency can have a dramatic effect on the detect ability of deep finds. It's in the first part of the post.

I guess my question now would be, did you see a noticeable difference in the difference freqs? Where you able to settle on one you felt was a better choice than the others? After that do you believe that it helped you gain depth?

 

[REVIER]

I went hunting yesterday and tried frequency switching but all seemed about equal at this site.
I also messed around with several different tone settings and even though I am leaning toward the 1F and 2F as favorites, I did try 1 as well as 3 and 4H and they all seemed to be pretty darn good on a few of my deeper targets.
All worked remarkably similar on the way deepest one I came across and dug to my surprise.

I love the 4h tones, I don't think I could switch even for extra depth. It's just too good for me on gold signals nickels.

Cant say I disagree much.
When hunting for jewelry or coins that are not all that deep 4H is still my favorite.
As a matter of fact on one of my first hunts with this thing using the 10" elliptical and hunting in a park trash heap picnic area that high tone nickel signal alerted me to something real nice and even though it was right next to some trash I still heard that high tone, went back and examined it further and ended up digging the final piece to complete a yearlong crazy goal.

Returned to the site were I located the small gold plated heart while using 1F tones. My hopes were, as previously stated, to locate at least a few older and deeper coins that perhaps others had passed over if I dig only targets deeper than 5 inches. My rewards for about an hours efforts were one ridiculously deep modern copper penny, one equally deep, if not deeper aluminium screw top bottle cap that was still on the broken bottle neck and more pieces of small foil and can slaw then I care to admit too.

So I gave up that venture for another time or site and resumed hunting with my usual more modest settings and 3H tones. Pictured are my rewards for the remainder of my stay including a little silver for my efforts.

FWIW, the silver religious medal at 3 inches deep ID'd as a zinc penny. On the surface it reads 66-67. Just barely into the dime range! Yes, as always, I still dig zinc penny's!

[Ayeti65]

I dig all zinc pennies, and most all repeatable signals for that matter you just never know when a whopper gold ring will reward you for your efforts.
