I switched from a M6 to a Vaquero because of wrist and shoulder problems. I needed something light,comfortable, with good disc,ground balance,reasonable depth, hot on gold jewelry,and stable around power lines. I was sure I need a TID machine until I saw some videos on You Tube of 53 Silver using the Vaquero. I tried one and bought it. One thing that I learned from another forum is that when you find a target and rotate the disc knob where it discriminates out and then bring it back in,if this target sounds cracky or fuzzy, it is usually trash. Even unbroken gold rings. I will try this out and see. Anyway learning new techniques is fun. HH and thanks for reading.
