I think most people missed my point regarding the Coiltek 10" x 5" search coil for the Equinox. Because that coil detects the entire length of the coil where the two "D's" overlap, I believe it is in actuality a full 10" inch coil, and is only one inch less than the standard 11" Equinox coil. Thus, it should have nearly the same depth of detection as the standard 11" coil in a much more manageable size (and weight). My 600 and 800 Equinox units with the standard coil are very "toe heavy" so that swinging the detector(s) are very tiresome because of a lack of balance. Not sure of its weight, but I have a feeling that the new Coiltek 10" x 5" inch coil could be "just what the doctor ordered"!
