Results for the F5 and 5" DD coil

Disc Mode & All Metal

First number(s) is ID
2nd number is repeat signal max depth

Due to EMI in my living room the gain was set at 30 (30%)

Threshold was at +6 (60%)
Everything else was at default settings for the F5



ring #1 disc mode ( 24 - 25 ) ( 3.25" ) +++++++++++ All Metal ( 24 - 25 ) ( 3" )
ring #2 disc mode ( 27 ) ( 3.25" ) ++++++++++++++ All Metal ( 27 ) ( 3.25" )
ring #3 disc mode ( 23 - 24 ) ( 3.25" ) ++++++++++ All Metal ( 23 - 24 ) ( 3" )
ring #4 disc mode ( 24 - 25 ) ( 3.25" ) ++++++++++ All Metal ( 24 - 25 ) ( 3" )
ring #5 disc mode ( 29 ) ( 3.5" ) ++++++++++++++ All Metal ( 29 ) ( 3.25" )
ring #6 disc mode ( 28 ) ( 3.5" ) +++++++++++++ All Metal ( 28 ) ( 3.25" )
ring #7 disc mode ( 28 ) ( 3.5" ) +++++++++++++ All Metal ( 28 ) ( 3.25" )
ring #8 disc mode ( 22 - 23 ) ( 2.25" ) ++++++++ All Metal ( 22 - 23 ) ( 2.25" )
ring #9 disc mode ( 26 ) ( 3.25" ) ++++++++++++ All Metal ( 25 - 26 ) ( 3.25" )
ring #10 disc mode ( 25 ) ( 3.5" ) ++++++++++++ All Metal ( 25 ) ( 3.25" )
ring #11 disc mode ( 26 ) (3.25" ) +++++++++++ All Metal ( 26 ) ( 3.25" )
ring #12 disc mode ( 21 - 22 ) ( 2.25" ) +++++++ All Metal ( 21 - 22 ) ( 2.25" )

14K chain section clasp area - disc mode ( 16 - 18 ) ( 1/16" ) ++++++++++ All Metal ( would not ID ) ( was detected at 1/16" )
gold nugget - disc mode ( 22 - 24 ) ( 3/4" ) ++++++++++++++++++++++++ All Metal ( 19 - 21 ) ( 1/8" )
14K small clasp - disc mode ( 22 - 24 ) ( 3/4" ) +++++++++++++++++++++ All Metal ( 25 - 26 ) ( 1/2" )
14K tear drop charm - disc mode ( 22 - 23 ) ( 3/4" ) +++++++++++++++++ All Metal ( 21 - 23 ) ( 1/2" )
14K leaf charm - disc mode ( 21 - 23 ) ( 3/4" ) +++++++++++++++++++++ All Metal ( 20 - 21 ) ( 1/2" )


Conclusions....

The F5 continues to get less depth in all metal than in disc mode.

The F5 is more sensitive to EM interference than the F44...
However the F5 has those awesome analog knobs (gain & threshhold) which gain quickly refute any EM interference.

I've noticed that rings which have a bigger hole size, get better depth than the smaller hole size rings. (even though the smaller hole size ring may have an equal amount of gold)
And of course the rings that weigh more will get better depth. (most of the time)

Next up the F44 and the 7" concentric coil.

I used a CZ and 5" coil on land from 1993 to 2018.
The CZ-5 and CZ-6a would get better depth with a 5" concentric coil than most detectors would with an 8" coil. :biggrin:
In those 25 years I dug a ton of silver with my CZ's however there was one test that my dual frequency CZ's failed miserably at...
And that was the dime next to rusty iron test.

In the photo is a silver dime next to a rusty piece of iron. The dime is actually a little lower than the iron as it sits.
Later on I will conduct a test with the 4" concentric coil on the F44 and the 5" DD coil on the F5...
I will cross the two targets horizontally and at a 45 degree angle...

Which detector will get the higher score?

We shall see...

I'm going to say the F44. And now for the legend of the "Golden Child." Back when I started detecting (1993), one of my hunting partners had a CZ5. It was a beast, there was something wrong with the factory tolerances. The needle never showed silver on a bent rusty nail. John would regularly come to our monthly club meetings with 20-30 silvers, double digit buffalo & V nickels, dozens of wheaties and Indian heads. Eventually the CZ5 needed repairs, he sent it off, when it came back it was not the same. :ranting: John purchased quite a few CZ5 's and 6's but never found that sweet spot CZ. Now his go to machines are the Whites Spectrum and the T2. He still crushes it, the T2 with the 5" is a beast in nail riddled railroad camps.

I want to do a quick clarification of the F5 test for folks.

1) the F5 Gain setting was on 30 (range is 0 to 100 in increments of 5)
2) the threshold was wide open (threshold setting are -9 to 0)
3) the small signal audio boost was on +6 (small signal audio boost settings are the threshold settings of +1 to +9)

So the F5 performance at such a low gain setting (30%) is not bad at all. Actually really good as compared to the F44 with the sensitivity settings of 12 (60%).

Looking at say,,,,ring #3. only a 1/2" difference between the two. I dare to say it but the F5 is the better performer.

Mike, both detectors being used are brand new and have never been outdoors. (to let everybody know)
We still have 4 coils to go... (7" round - 8" round - 10" teardrop - 11" teardrop ) all 4 are concentric.

Going in I knew the F5 was a deeper machine and the F5 has proved it.! (so far)

However I'm a trash hunter and I love to hunt the trashy areas.
The metal detector world is a "give and take" world.
Meaning that if a detector gets great depth like the F5 then it is most likely not going to do as well in the trash like the F44 would.
Because the F44 will not go as deep as the F5. ( It's all about physics )
Example: In the 1990's we had the Fisher 1266X which could pull silver dimes out of the ground at a depth of 16" :biggrin:
But in the trash the 1266X had target separation problems and would ID iron as good signals at depths that it shouldn't.
Then also in the 1990's we had the Tesoro detectors which would not go nearly as deep as a 1266X but would "lay waste" to a 1266X in the trashy areas.
I know this because I used a Tesoro Stingray II out in the lakes for several years.....

I'm also trying to figure out if the F44 is better in the trash than the F5.
And can I figure this out from my living room with out going outside in the snow? :biggrin:

I have many more tests that I will be conducting... (Including an iron discrimination audio test) :biggrin:

In the meantime... I'm glad that I own both detectors!

Steve,
I'm glad you are doing all the testing. Its a lot of work and you are doing a good job. I was just just highlighting the difference.
Keep it up!

Mike,

We also have coil battles that are brewing...

The "I can go deep in the trash" concentric 4" coil vs the Target Separating Bad A$$ 5" DD coil.

And the "Take me anywhere honey" Super 7" concentric coil vs the "Don't take me into the trash please" 10" teardrop coil :lol:

This is going to get a lot better before it gets worse. :biggrin:

After the gold & platinum ring testing has been completed we will go into the "Dog & Pony Tricks" portion of the bench testing.

I'm convinced one or maybe both the F5 & F44 has "see thru" abilities in the trash.

The F5 will be equipped with the 5" DD coil and the F44 gets the 4" concentric coil.

There will be several puzzles involved and each detector will try to detect the silver dime coming from 3 different directions.
( horizontally & vertically and at a 45 degree angle )

One of the puzzles that will be in the test I have already built. It is called "The Bridge over the River Kwai"
Can your detector detect that dime?

During the testing... I will be the Judge, Jury and Executioner. :lol:

There will be coins on edge, coins under bottle caps, coins under coins, this will be very interesting I promise you.

All this coming up later.... Now who ordered this dang snow? :shrug:

From here on out I am going to run the threshold at zero on the F5 rather than +6 due to EMI in my living room.

And the F5 will go first in all tests so that the gain used by the F5 can be matched by the F44.

Results for the F5 and 7" coil

Disc Mode & All Metal

First number(s) is ID
2nd number is repeat signal max depth

Due to EMI in my living room the gain was set at 30 (30%)

Threshold was at 0 (zero)
Everything else was at default settings for the F5

ring #1 disc mode ( 24 ) ( 3" ) +++++++++++++++ All Metal ( 24 - 25 ) ( 3.25" )
ring #2 disc mode ( 26 ) ( 3.5" ) ++++++++++++++ All Metal ( 26 - 27 ) ( 3.75" )
ring #3 disc mode ( 23 ) ( 3" ) +++++++++++++++ All Metal ( 22 - 23 ) ( 3.25" )
ring #4 disc mode ( 24 ) ( 3" ) ++++++++++++++++ All Metal ( 24 ) ( 3.25" )
ring #5 disc mode ( 28 ) ( 3.5" ) ++++++++++++++ All Metal ( 28 - 29 ) ( 3.75" )
ring #6 disc mode ( 27 ) ( 3.5" ) +++++++++++++ All Metal ( 27 - 28 ) ( 3.75" )
ring #7 disc mode ( 28 ) ( 3.25" ) +++++++++++++ All Metal ( 28 ) ( 3.5" )
ring #8 disc mode ( 21 - 22 ) ( 2.25" ) +++++++++ All Metal ( 21 - 22 ) ( 2.5" )
ring #9 disc mode ( 25 ) ( 3" ) +++++++++++++++ All Metal ( 24 - 25 ) ( 3.25" )
ring #10 disc mode ( 25 ) ( 3.25" ) ++++++++++++ All Metal ( 25 ) ( 3.5" )
ring #11 disc mode ( 25 - 26 ) (3" ) +++++++++++ All Metal ( 25 - 26 ) ( 3.25" )
ring #12 disc mode ( 20 - 21 ) ( 2.25" ) +++++++ All Metal ( 20 - 22 ) ( 2.5" )

14K chain section clasp area - disc mode ( would not ID ) ( barely detected at 1/16" ) ++ All Metal ( would not ID ) ( was detected at 1/16" )
gold nugget - disc mode ( 20 - 23 ) ( 1/16" ) ++++++++++++++++++++++++++++++++++ All Metal ( 19 - 22 ) ( 1/4" )
14K small clasp - disc mode ( 22 - 23 ) ( 1/16" ) +++++++++++++++++++++++++++++++ All Metal ( 21 - 23 ) ( 1/4" )
14K tear drop charm - disc mode ( 21 - 23 ) ( 1/16" ) +++++++++++++++++++++++++++ All Metal ( 22 - 23 ) ( 1/4" )
14K leaf charm - disc mode ( 20 - 23 ) ( 1/16" ) ++++++++++++++++++++++++++++++++ All Metal ( 21 - 23 ) ( 1/4" )

Conclusions....

By keeping the threshold at +6 this increases the depth in disc mode and decreases the depth in all metal.

By reducing the threshold from +6 to zero this reduces the depth in disc mode and increases the depth in all metal.

By keeping the threshold at zero we will get a more understanding of what the F5 can do.

Because when I'm hunting those old parking strips over in Seattle there is no way I will be able to run the threshold at +6
due to all the EMI from the power lines.

But if you are way out in the country hunting Farmer Jones' farm field than by all means jack up your threshold to +6 so you
can get more depth in disc mode.

Next up the F44 and 7" coil with the same gain setting as the F5 just had.
