I know now why the F5 is listed as being a prospector:wiggle:

Besides just the Ground balance resolution.

Was doing some air testing with that little gold chain I found and the F5 hits it really good. My Golden just barely hits it with a maxed out sens and the 4" coil. The Coinstrike doesn't even know its there. My F5 hits it at minimum(05) gain and 0 threshold. Unbelievable

With a setting of 50, +5 I'm getting good audio at 4". Four inches on a small thin gold herringbone chain. Not the clasp, the chain. Not piled up, not doubled, just layed straight out as a single strand. In DISC mode

You get that? 4" on the chain in Disc mode with mid range settings.

Gold nugget test

These are my findings so far for the F5 with mineralized test bed. (Tailing's from my high banker and dessert fox)


13 grain or .84 gram 5 inches

6.3 grain or .408 gram 3 inches

2 grain or .13 gram 1.75 inches

I had the machine in all metal mode

Air tests add about 20% more depth.

Bob, thank you very much for this information.

Those are great numbers for small gold.

Wow. 13 grains is match head size. 5" in the ground! Mineralized ground! That is

Half that size, 6 grain, at 3".....whoa! Pickers at 3" in the ground! That is

2 grain and the F5 doesn't surrender. It still picks it up at nearly 2". That is

That is just plain hot.
