what the difference between the musketeer and sovereign? they both go thru trash,but one has dials on it to fine tune. i would think the musketeer would be the same but without the fine tuning and that would make it easier to use. now the eureka gold has more frequencys,but is it a better machine for hunting coins than the other two?as far as hunting coins and the frequencys is what im interested. i hunt coins on the beach,in the woods and im trying to choses which machine to get for hunting coins and rings.why pay more for a machine like the sovereign if the musketeer is the same,but has a auto trash instead of a fine tunning knob for trash. which is best and why?
