garimpo Posted April 21, 2009 Share Posted April 21, 2009 I'm sure this question has been brought up here sometime in the past but since I have severe CRS I decided to ask Coiltek and here's their reply...from the President of Coiltek...as us old timers would ..."from the horses mouth"... This is a common query and I hope I can explain it for you. If we had an 18" round coil and a 18x12" Elliptical then the round coil has a broader field area and would have the better depth however its sensitivity will be reduced due to the wide field. Not greatly reduced but a noticeable difference from a 14" round. The Elliptical coil has a tighter magnetic field where the ellipse is at its tightest and therefore will have better sensitivity and pinpointing ability but will not have the same depth as the 18" round. To get close to what the 18" round performance you will need a 24x12" Elliptical and still some would say the round will go deeper. I like the elliptical coils because they have good depth and excellent sensitivity and pinpointing ability. If you want overall performance then the 18x12" elliptical or the 24x12" elliptical can cover your needs. If you need depth performance more than sensitivity then the round 18" coils will help you.

garimpo Posted April 21, 2009 Author Share Posted April 21, 2009 Hi Unc...I asked Coiltek if everything was equal....which of the two coils (round/ell) would give the most depth and sensativity.....my mistake for putting DD/MONO at the heading....
