$40 difference - 12x10" Vs SEF

[goldnrelics]

Should i have spent $40 more for an SEF coil or should the regular 12x10" do just as well? it's 2.9 lbs btw

If you don't have mineralized soil I would have went the same route and skipped the SEF. The concentric is deeper but you must overlap passes to take advantage of it. In my opinion the concentric has better target separation. Some will disagree.
