hello folks just wondering for those of u have or have had both of these machines which do u prefer and why. please dont comment if u have not had both of these machines. im looking for operational info on these machines and how they compare in real world hunting situations and the pros and cons of each. i have heavly reaserched both of these machines and know all the specification info of each, khz coill selection features etc. i have had some swing time with the at gold and its a decent machine but the f70 interests me also. i am mainly a silver coin hunter,token hunter and button hunter.thanks in advance if u have any pertinent info for me cheers
