I also
had a G2 since they were released and I borrowed it and a Fisher Gold Bug Pro. I used only the 5X10 DD and 5" DD coils. I mainly search older-use locations, generally abundant with trash, especially iron-based junk like nails, washers, rusty tin, etc. I parted with my G2 because I had other detectors in my arsenal that worked better in dense iron nail conditions, and while I hunt for anything of interest, I am mainly searching for older coins and trade tokens.

I'm a coin hunter, and wanted to see if the F19 handles coins (especially silver) as well or better than a Gold Bug Pro (or G2).
I found coins with the G2 I evaluated and posted a review on back in October of 2010. It worked fairly well in old house tear-down sites with a lot of metal debris, mostly smaller pieces, but in the end the G2 was at-its-best with the 5" DD coil that I left mounted, but in the nastiest of iron trash, it was no match for some models I already owned and used.
I was most let down by the poor performance on the higher-conductive targets, to include the better copper cents, and all clad and silver dimes and quarters. It was just a sub-par performer on silver coins, especially if modestly deep in some bad ground, even let's say at anything over 4".

My specific questions are:
1. How do the depths compare? (Stock vs. Stock, or 5" vs 5")
The F19 was very similar in depth.

2. Does the F19 find coins in iron as well as the GBP?
I didn't think the G2/Gold Bug Pro were that good in dense iron, but I did find the F-19 quite improved, even to the point where it gave reasonably good performance on my
Nail Board Performance Test, which had an Indian Head 1¢ or silver 10¢ placed in the center of four iron nails that surround it. The G2/GBP usually got 1 good hit out of 8 possible responses, and the F19, using the exact same search coils produced 6 good responses on the coin. 6-out-of-8 is good performance on this tough iron nail condition field test.

3. Is the audio on deep silver better (louder) on the F19?
No. None of these models are what I call excellent, very good, or even just good on audio responses to 'deep' silver dimes and quarters. I don't have good hearing, but even with my White's Pro Star and Killer B 'Wasp' headphones, I certainly wouldn't use 'loud' to describe their response on deeper coins, especially higher-conductive metal types.
