I've got a new Tejon coming to me from a forum Sponsor; its the Black model with the 11x8" coil. I hear nothing but good from users that opt for the smaller 5.75 coil but the question is, which one? The concentric or widescan? I like that the widescan can pinpoint and size off the edge of the coil, however, I"m concerned about the inherent love that DD coils have for bottle caps. Are bottle caps a problem for the little widescan coil? Is so then I feel better opting for the concentric coil. Any thoughts of you users of the Tejon, Vaquero or Cibola for the two coils I'm considering?
