In May of 2013 I bought a nice used Explorer SE. I haven't hunted much due to a serious health issue that almost took my life. I have been metal detecting off and on since 1977. I only can get out for an hour or two at a time and have found a good amount of clad in the parks with the SE. Most of my good spots are in fields and I wonder if my time would be spent better with a larger coil such as the 10x12 SEF. There seems to be pretty good reviews on the SEF and I would like to optimize my time. Thoughts and suggestions? Thanks!! Ted
