F70 air test

[WV62]

Folks I would like know what the F70 will do air testing. So I was hoping that I could get somebody that knows the F70 pretty well to air test it on a clad quarter and if you happen to have a small gold item that would be great.

I would need to know what coil you are using but it needs to be either the 10

Would one of you poindexters step up and help Ron? I would, but I have a problem with exaggerating, or bullcrappin' if you will, plus, I dont hunt deep...

... maybe even get a vid of it?
Heck, this may be a fun project for all of us this weekend! .i'm curious myself just how far an F70 can hit a Q depending on the settings in the air...and how about a tiny split shot of a certain gram to replicate a gold nugget?...

I"m probably not the guy that can give you the best information regarding the F70 as i don't have a lot of experience with it but i can do some air test results and post them later tonight if no one else post, i can say that i have been playing around with all my machines in this horrible weather. and the F70 with the big 15" DD has no problem hitting a quarter at 15 inches in a air test. I don't have a 11"DD, i have a 10" eliptical and a 5"DD, i can test out and post the results. And i won't bullcrap you

Sounds good to me, please use your 10" elliptical.

Thanks

F70 Air Test with Fisher 10" eliptical

Settings-

Program 1
Disc------------- 0
Speed---------- de
Sensitivity----- 80
Threshold----- -1
Tones---------- dp

Air test with these settings the Quarter was a solid repeatable signal 9.5", and a diggable signal at 10", as at 10" it didn't repeat every time, but was a good signal, machine was a tad bit chatty, probably due to house EMI.

Did the same test with a dime, good repeatable signal at 8", at 8.5" the signal i got i would have dug if i was out hunting, but wasn't repeatable everytime.

Did the same test with a silver Quarter and silver dime, the depth results were basically the same. There seemed to be no difference in the signal between the clad and the silver.

Hope this helps ya out GL.

F70 Air test on a womans small gold ring, 14k i think? i can't find my loupe and i can't see the markings with just my glasses.

Same settings as the coins in my coin test post

good repeatable signal at 7" with the 'round' ring facing the coil, but with the 'edge' facing the coil about 3.5"- 4" good repeatable signal. This was a small ring.

Hope this helps ya out. GL.

You were right no bull. I must say you have a good way to described how you got to your 10". As I read that it was the same as I thought when I was testing my F5. Very nice testing job. Now I must ask one question did you work your settings up to the best depth or did you just take a shot?

Now I will let you know what I was getting on my F5 with the 10" coil. I am getting 13" and I did work my settings up to the max and then as I went higher or hotter settings it started to drop off.
I also found that there was not a lot of change from clad to silver, that is why I just stay with clad.

Now I could still use some numbers the 11"DD.

Thanks a lot,

I must have been typing when you posted on the gold. I checked my work sheet and I was getting 9.5" on a small gold ring. I did have a smaller item of gold it was a gold ear ring stud and I was getting it to about 3".

Now I did my wedding ring which is a mans but not on the large side (I am kind of little guy) and I was getting it out to 13.5".

Again thank you so much,

I set my machine to the point where it was still usable, it can probably get more depth with a higher threshold and sensetivity or SL speed, but in the house that was about as high as i could go and still use the machine.

One more thing about my settings, i am probably more conservative on my setting than some or most people are, cause i like a quiet machine "not chatty", definitely could squeeze more depth i think, especially outside. Also i think the 11" will do better than the 10" eliptical. HH.

Here is an air test chart one of the other members posted a while back, maybe you can glean some information from this concerning setting. This is for the F5 but seems to hold pretty much true for the F70 too.

Yeah thats right! Knarfj did some huge tests on the 70 back on Dec 20th!

posted under the title "What does one do in inclement weather" Y'all should go have a look, page 2 of the thread is full of settings and air tests..
