Bought the Vaquero 7 months ago, the Cortes last month. The V. picked up hot rocks a lot less where I used both machines. Right now, I like the C. a little more because the visual ID and depth indicator gives me sort of a clue. Haven't used the two notch modes very much yet, but another poster said the wide notch is great for ladies gold rings in trashy picnic table areas, sounds great, but it will eliminate the larger gold rings that fall in the pulltab range. I mostly search for jewelry in parks and so far I'm still digging the same amount of trash with the C. since a pulltab or foil ID reading could very well be a gold item, we all know that. The C. eliminates the need to twirl the disc. knob, and I like that. An air test shows that the V. is more sensitive to a girls small gold bracelet, but the C. seems to pick up gold rings just about the same in an air test. I will probably switch back and forth between machines and use only the V. at the beach.
