Maybe, but I'm not having any problems finding dimes/coppers at 8" with the F2 using the 4" coil. Also hitting them at 9" with the XTerra. Lower frequency detectors generally do better on higher conductivity metals (silver, copper, etc...) than the higher frequency machines. Also some deeper signals on the Vaquero were so short and clipped sounding, I couldn't tell if it was a deeper coin or just some rusty metal that wouldn't disc out. In my test garden, that is exactly how the dimes would sound past 5". Very short signals, sometimes intermittent, that sounded like a tiny, earring sized target. I never would have dug those signals in the field. Now supertuning would up that to 7-8" easily, but it was too unstable to use at most of my sites with sens nearly maxed out. I busted my back constantly digging trying to figure out if those short/clipped signals were deeper coins, or just iron. That is not the case with my current detectors. If it's a coin it's always a solid signal, regardless of depth. Higher freq detectors like the V tend to like iron more, that's just the nature of the beast (maybe that's why the V has a great reputation for relics?) If it works great for you that's awesome. This is just my own personal experience with the V. It's a great machine for some people, I guess I just didn't have the patience after a year to keep trying to learn it. All machines have idiosyncracies that have to be dealt wth, I just eventually grew weary of wondering what I might be missing out on. HH
