I have a mint explorer se pro in the mail,but instead of the pro coil it has a slimline coil..The machine has the red letters on the side of box so it is the se pro,but must have had the coil swapped out..so,is the slimline coil good,and if not should I get the pro,ultimate or 10x12 sef? I mean,if I’m gonna buy another coil I’m only buying one and want the best for the machine and places I hunt,,large parks and yards...Thanks for any input.
