Before you blast me I know the Vaquero is a Great detector But I love the old Tesoros and traded it for a Cutlass II umax and a Silver sabre II both with 8 inch Brown coils . After putting in fresh Batteries and doing some air testing "which I know" is just that "Air testing" it seems the Silver Sabre II wins out I am going to move the control head to under the arm cuff on it but I must say I have owned a lot of Tesoro's in the years past and loved them all . I like the Vaquero just did not like the fact of the coil choices . Would like to hear from those that own either of these your honest opinions on them and I have read all field tests on both units by the way . Also buried a silver dime at 8 inches in the sand in my yard and the Silver Sabre hit it but the cutlass was a litlle iffy both have the brown 8 inch coil .
