Just a quick air distance comparison. The Vaquero would hit 3/4 of an inch to an inch deeper than the Cibola..This on all the coils, std, 5 inch conc, and wide scan, and the clean sweep..Ohio ground here is mild and there was a bit more difference with my V grounded out.. I have a ten turn pot,which really ups the sensitivity. ADDED ON.. I did not use the 3 by 18 coil on the Cibola because it does not have a manual ground balance...I've been finding that addition of the clean sweep coil (once balanced out with a stock coil for the area) requires a GB adjustment to be perfectly balanced... My comments on a ten turn pot vs std three turn.. Only do it if you are going to use the clean sweep and wish to maximize your depth....
