Ya'll gotta get the 9x12 coil,I'm a newbie but it doesnt take a rocket scientist to tell the difference between the stock coil and this one.I went to a old church today that I have been to at least 25 times since I have had my 250 I have found lots of clad and 1 wheatie,today I found 3 wheaties and a v nickal and lots more clad I hunted the same spots on purpose to see if I could tell a difference.This might just be luck,but I'm leaving this coil on,the only down side is its a little bit heavier.
