Field testing of the 19″ Evolution in the Victorian and SA goldfields has proven this coil to have exceptional depth and stability, and a high level of sensitivity to smaller nuggets has been retained. The Nugget Finder Evolution search coils provide a sharper target response on both smaller and larger targets, for maximum performance. The 19″ Evo will be sure to impress with its light weight and stable performance on a range of gold sizes. Weight approx. 1100g.
