Additional Details ------------------------------ Product description: Coiltek 17 x 11" Goldhunting Anti-Interference for Minelab SD, GP, GPX Detectors C02-0009. Another all-round performer, it delivers balance and good maneuverability for tight areas, plus excellent depth and sensitivity. The large elliptical shape gives good ground coverage with the tip making pinpointing of targets easy. Searches in and around terrain and finds sub?gram pieces with ease. Operation hints tips: With its excellent detecting capabilities you will find that this coil will ensure you have a great chance in the field as it will search deep as well as seeing the smaller sub gram targets quite easily. By keeping the coil close to the ground (no more that 1 inch above) you will find that the 0.1 gram nuggets can be heard at a couple of inches which is proving that the coil has good sensitivity. When pinpointing, slowly work up to the target and listen for the first response heard. Usually this is within the first inch in from the tip of the coil. Then repeat the process at 90 degrees from the first direction. Once you have a crosshair view of the location it becomes a lot easier to accurately dig for the target. The DD PRO allows the operator to have quiet operation in the heavier mineralized areas ensuring faint target responses are heard. Needing only to overlap the coil by one third, this coil can cover the ground quickly due to its elliptical shape making this a great choice for the more open areas in the detecting field. This is a good medium-sized patch hunting coil. Applicable metal detectors: Minelab SD Series Minelab GP Series Minelab GPX series
