[QUOTE="Ridge Runner, post: 343934, member: 3775"] As GP posted in that picture the pickup are runs from front to back although they can also pickup signals from the side they are focussed to about an inch to about 2 inches wide front to back, With some DD's they can have a dead zone where the Two D's meet back to back which is at the Centre of the Coil, The SEF Coils are not quite as hot as the Whites Coils which does help a lot with dealing with Aussie Dirt and that helps with ground balancing and being able to run the Gain a fraction higher which leads to more depth, And even using the same Gain settings the SEF coils seem to go deeper in Hotter Ground because being less sensitive they do not get over run with Ground Noise, In Noisy Ground the 8x6 SEF can go Deeper than the 6x10, In anywhere else in the world I would try and stick with the Whites Coils, But in Oz I would have to say go with the SEF Coils, The 10x12 SEF is a great Coil and the 12x15 would be the biggest one I would want to use, But your 14x10 is about the Best overall Coil where it offers Depth and Ground Coverage Yet it is about the same weight as the whites factory 10" round DD, and the 14x10 goes a few inches deeper, hope that helps.
