Does frozen ground effect ground balance?[/quote\

I've never actually detected "Frozen" soil so, I'll let somebody else answer that!
But, I'm pretty certain that "Frozen" soil would have its greatest effect on 'DIGGING' :rofl:

Seriously, I do know that certain batteries tend to fail, or discharge WAY more rapidly in freezing temperatures then others.

Well, this somewhat fixes my earlier post if I get the tags right this time.

I have reread the answers on this post and I am very happy with what you said. I am loving these posts and I think they were the most complete I have ever seen. It is hard to replace your experience.

During the few “nice” days in NE Ohio this winter, I have worked a few yards to tried to get “used” to the F70. (I am coming from a F2.) I did what was suggested and it was working.

I went to a new beach, for me, and the black sand we have on Lake Erie is incredible strong. Getting away from the “noise” was challenging. I will work it out.

I write too much. I just wanted to say thank you for helping me adjust to a new machine. I hope I learn enough to love it like my little F2.

I went from the F2 to the F70 also, plus I have hundreds of hours using Tesoros so I listen closely to the audio part of this thing is and it has been important especially on a few weird target situations.
My first detector was a horrible unit that had problems, couldn't handle my hot soil and falsed on almost every swing so I had months of training listening to noise and learning to pick out the real targets in all that mess.
A frustrating cloud of confusion but the silver lining was I got used to noise and hyper sensitive to audio clues.
Loved the F2, learned the language and got a pretty deep understanding of the behavior and boy that thing produced for me and paid for itself more than 10X's over in 3 seasons.
The F70 has a lot of the same language but there is so much more, the million combinations possible by adjusting the settings just adds to the enjoyment.
For the first 10 months I was really anal about examining and experimenting with almost every signal, changing settings up down and all around to see what effect they would have because that's how I learn best.
My typical volume of finds suffered because I dug way less than usual but I still found some jaw dropping targets along the way and when I finally settled down with a few favorite settings and hunted my finds totals grew exponentially.
Now I am into this thing a little over two years now, still experimenting some, still learning new things and for as much as I know , as much as I have found and accomplished I really believe I have barely scratched the surface of its abilities.
I can make it ultra quiet or any and everything up to super noisy and it has done the job and shocks me often.
I have found that there is no wrong way to use this thing...there are as many different setting combinations that work and work well as there are different soils and conditions and different hunters that use them.
I have been more successful than I have ever dreamed I could be in conditions that range from ultra mild and great to extreme iron infested to super trashy to heavy mineralization...it has never let me down and my jaw aches from dropping so much.
From low sense to low disc, high disc and higher sense, different threshold numbers, all the tone settings to factory to my maxed out all metal blast through settings, look at how many use these here, what they find and how they differ in their favorite settings.
We all seem to love these things once we get used to them, and we all seem to be able to find the good stuff doing it in so many different ways.
Boredom is a big thing with me, I don't think I am in any danger of getting bored with thing for a long time if ever.
My bucket list items are being checked off one by one as we speak.
Man I love this thing!

Since there seems to be a lot of experienced F70 users here, I have a question to ask: I've never used any other machines than the 7.8 Khz machines that Fisher/Tek makes. Is the F70 easier to use than either the F75 or T2 (the regular versions, without boost protocols) ? Or in other words, apart from cost concerns, would there be any other reason to choose an F70 over an F75 for example ? I don't really want to start a debate over which is better depth wise or whatever. I just want to know why some people would choose an F70 over other detectors of same frequency. Thanks.

What's not to love?
In my case a brand new in the box F70 came my way for $400 as I was saving up for an F75 and that was that.
Regarding boost don't let anyone tell you we don't have it because we do...and had it first.
It is called SL speed and a slightly different process than the F75 but with exactly the same effect.
Some want all the whistle and bells, can afford it easily, so why not?
All kinds of cars out there and they all have 4 wheels
Others don't mind missing a few things, don't consider them a huge loss....if we never had them we don't really miss them.

The F75 has a few cool extras, it has that trigger feature, you can manually adjust the GB numbers vs auto GB on the 70, the notch system is a little more controllable where you could knock out half of a chosen range instead of all of it, it has a backlight, a few more factory programs and a cache setting.
None of that matters to me the way I hunt, the notch stuff could come in handy in a few tab infested parks but I can live without it.
It comes down to whether you want or think you need all the extras or don't...in my case I don't but others prefer to have all available features at their disposal.
The F70 is built on the same engine as the flagship, uses the same coils as the flagship and pretty much behaves the same using those coils.
Comfort filled or rat rod...unusual that a company would have a choice like this but that is what made the F70 earn the name "sleeper".

Dave Johnson, (woof on the forums), a top respected head design engineer at FTP said this once about these two on another forum when asked pretty much the same question...

Quote
woof!
"The F70 was the product of a mission-- to come up with a less expensive adaptation of the F75, while incorporating things we had learned meanwhile. Without "dumbing it down". Because the F70 was advertised for a lot less money than the F75, marketing dept. didn't quite dare to say how good the damn thing really was. Some of the secret sauce we put into the F70 eventually made its way into later revisions of the F75 group of machines, as well as into the Teknetics "Fratbros" series and most other new beeps introduced after the F70.

As the top of the Fisher lineup, the F75 including its revisions got all the attention. That's how the F70 became a "sleeper". Guys like Mudpuppy will never have to wonder if they should have gotten an F75 instead.

This is the same sort of explanation I just posted in "another forum" about the approx. $200 category. If you get a Eurotek Pro, you never have to wonder if you should have gotten something else. Get anything else, and you'll wonder if you should have gotten a Eurotek Pro instead. F70 owners never have to wonder if they should "upgrade" to an F75.

--Dave J."

I've used an F70 for a couple of years, but have never used an original vanilla F75. With that said, I would personally go with the F70. It's newer and I'm sure has some newer technology. I believe it might weigh a little less too. I think I recall NASA-Tom saying that the F70 is on par with the original F75 depthwise when the SL mode on the F70 is used. The F70 is a great machine, and quite a bargain in my opinion.

Now throw the newer F75 LTD with DST in the mix and some things might change a bit.

I've never heard the first bad comment about the F70 anywhere on this forum, only positive feed back from anyone who owns one. This machine is perhaps the best bang for your buck, I'm using the f5 right now and it's a great machine also but if I ever decide to move up it would be the f70 for me.

The F75 is the flagship, it has all the presets/programs ready to go at a touch of a button.
The F70 is the workhorse, not as "elegant" as the F75, but will get the job done with the proper settings.

The thing to remember is you have to put in the time for ANY machine to get the best out of it.
Also, you have to "like" the machine. I hear others tout the praises of the AT-Golds and AT-Pros, but I cant stand their tone.
I kinda feel the same about the GBP/G2, but can tolerate them a little better.
About the only other machine, at this time, that I would like to have is the x-terra 705. I like its tones and its "prospecting" mode would be fun to try in the goldfields.
But like Rev, my F70 came to me for less than $400. add a couple coils and I don't feel "under-gunned" in most situations.

There are machines that have more features, but the F70 will always have a spot in my gear bag.

By trigger, you mean the one underneath the box that is used to ground grab/pinpoint like the T2 ? The F70 has a push button for that I suppose ?

Yep, seems to work fine even though the buttons are on the face.

I haven't picked up my F2 since I got the F70, but I met two people at my local neighborhood park that have them and don't have a clue about them so I offered my help.

On the other hand I have a friend on another forum, just joined up here,that had an F2 and just got a new F70 like 2 days ago.
I said I will help him get over that initial learning curve with some setting advice but he seems to be doing fine so far.
On his first time out in his own backyard he turned the thing on and swung.
Doesn't really know anything about it at all, not about ground balancing, all the tone options, the thresh or even that it has two programs you can set and switch between at will.
Just turned it on, used factory settings and on his first hunt found an 1875 IH about 5" deep that was loud and clear.
Bodes well....but using a Fisher I would expect nothing less.

Thanks for the mention Revier! I am very new to the F70, and I have lots to learn, but I am amazed by this machine. I really shouldn't be too surprised though, I mean I am a huge fan of my F2. I look forward to learning more about the F70 from all of you. Thanks for posting your knowledge and experiences with the F70 for all to learn.

Awesome knowledge and dictation in this thread. I have been using an f70 for a couple years now after graduating from an f2.

I have a question myself and didn't want to start a new topic as this can fall within this thread.

When using SL, it there a certain technique to use? Swing, slow swing, quick swing, hover, wiggle, pump?

I've mostly used DE but have been running over old ground in SL and finding things I missed so I am highly motivated to learn using the setting.

SL means slow....The processors are faster in DE but SL gathers a bit more info and goes a bit deeper if you move the coil at a very slow pace.
SL might be a bit noisier in certain situations but lately I am using it most of the time and just turning the sense down if I want it quietet and still get clearer signals from deeper depths.
Soil conditions and site conditions matter, in really trashy sites DE and it's quicker response time is better, curiously in heavy iron SL works better for me at picking out the good targets as long as I am moving that coil slow and I mean painfully slow in some sites.
Keep in mind I hunt in very difficult iron tested mineralized soil where SL works well, in much better Kansas soil DE worked pretty good although SL still got a bit deeper.

All targets I acquired I make quick sided to side passes with the center of the coil, any coil, and make sure all positive numbers, tones and behavior repeats, on deeper targets I do the same from a 90 degree angle and if it matches I dig.
I do wiggle and pull back to pinpoint the target using DD coils, hopping up and down over some higher number targets can reveal their actual identity as iron if the numbers drop down to iron continually as you do this.

On thing I do remember is using SL on several hunts for several hours and then after switching back to DE I could really tell the difference in the speed of the processors.

Both have their place.
