I like, no love the Vaquero. I hunted around a house built in 1945 .Didn't find anything old , lots of clads . I found a lead split shot at at 12 inches deep I measured the depth. Most of the clads were at 8 to 10 inches deep, found out from the next door neighbor that fill dirt had been brought in many years ago, that explains the depth of the clads and no older coins, the Blackwidow headphones work great, this house is located in town by a lot of traffic , the headphones blocked out all the traffic noise, a lot like when you go into a sound proof room for a hearing test. Anyway I'm pleased with both the Vaquero and the Blackwidow headphones.
