JUst got a Musketeer advantige ,and i was doing some testing whith it and my observation are,, the musketeer is very deep on coins far deeper than my Golden . silver, compadre. and cibola , BUT on gold rings the tesoroes exell, probly because of the higher frequincy the tesoros can pick up a pencil eraser better you know the aluminum ones and im not mocking this is a good trait and the tesoro machines in my opinion pinpoint far better If i was going to hunt the scool yard or beach i would take a tesoro but if i was looking for deeper silver coins the musketeer is far better i can peg a dime at 8" using the 7" minlab coil did not seemuch diffrence between the 7" and the 10" coil I have never used a vaquero but I bet its good whish tesoro would get a 12 khz increas gaing detector whith a ground bal and make a 5" concentric and a 7.5" widscan and a 9" widscan i bet it would be a winner
