Santa brought me a 7" coil for my MX Sport and I finally had a chance to take it for a spin in the park yesterday and today. Ran it in Coin and Jewelry at a sensitivity of 4-5 depending on the level of trash. Nice coil. Highly recommend. Deep and sensitive. Very easy to pinpoint. Found two wheaties- 1955D and a 1945 and a pretty little sterling ring with some very small stones inset, along with the usual clad and some trash. Rarely find wheaties around here so counted as great finds, and sterling rings are always great finds. Very happy with the coil. If you have a Sport you definitely want this coil for the trashy hunts.
