T-DUB, usually a nickel VDI's in the 18-22 range on the DFX or V3i. But the War Nickels, because of their composition, can VDI as high as 35. I rely mostly on the audio response. At a sight that yields wheat cents and or silver coins, I dig just about anything that gives a good audio response and pinpoints coin or jewelry sized. Best of luck and...15 years of swinging, still no War nickel. I have never dug a trifecta of anything either. I have been fortunate to have dug some good stuff over the years, thankful for what I have dug.
