Hello,
I have the 10" DD and have been very pleased with it's depth and it's ability to work well and quietly in mineralized soil. The sales pitch on the SEF says it is deeper and works better in mineralized soil. It's hard to believe there is something that works better than the 10" DD, but some say there is mineralized soil where it won't work well. I've been as far south as mid South Carolina and as far north as Richmond, Virginia with the 10" DD with no problems. Do I really need the SEF coil?
