Thanks for the comments. You guys might be right but I've hunted this spot with everything from Nautilus machines to Fishers to Minelabs to a Technetics T2 and I've dug a ton of stuff. I'm just saying that the Vaquero easily and clearly picked up stuff I missed with the others. And I've hunted the spot for 20+ years off and on. The scabbard tip was a bit away from the most concentrated iron so maybe I just never happened to walk over it. But everything else was in an area that I've hunted in tight rows. Many many times. It is chock full of iron chunks, nails and bits and pieces. And it drives most machines I've used crazy. The Vaquero just cruised right through it and barely made a sound until I hit non-ferrous objects. I will definitely hit it again. But not with any other machine.
