Been using the new Impact with the latest 13.11 software for 6 weeks on goldfields and cannot fault it as a nugget detector.It is stable and a delight to use in very highly mineralised ground and discriminates iron and hot rocks easily in the GEN or general mode.I gather for coin hunting most users will use the many discrimination modes on offer for any situation.The 11 inch coil in GEN with 20 Khz. picks up really tiny steel flakes 0.1 gram size at 4 inches deep.
