Nugget Finder 19″ Evolution Mono

The largest Evolution Coil currently available. The round design offers outstanding Depth and Coverage with surprising Sensitivity to small gold. This coil is Monoloop in design, and compatible with all Minelab GPX, GP and SD Series metal detectors. Includes skid plate. Only available in Open (or spoke) design. Weight is only 1120 grams. Evolution Technology: In traditional bundle wound Litz coils, the individual turns of Litz wire are grouped together to form what essentially looks like a rope of wire. The Evolution Coils use the same Litz wire; however the individual turns of wire are laid side by side to form a wide flat strap of wire. This method of winding is called a Flat or Spiral winding. Flat winding reduces the capacitance between the wires and produces a much more efficient coil. It also dramatically increases the surface area of the winding, thereby producing a coil with both improved depth and sensitivity across all target sizes. This method of flat winding has been used for many years in custom made and privately built coils. It is considerably more difficult to produce this type of winding in large quantities without sacrificing quality. Nugget Finder has developed a unique method of producing a flat winding which ensures that reliability and quality are not sacrificed. Every Evolution Coil winding is individually wound on a former, then clamped under pressure between two layers of high density Divinycell Foam. While clamped, an expanding foam is injected between the layers permanently infusing the winding into the foam. When combined with our unique bonded ABS and Polycarbonate component housing, the result is the highest quality search coil on the market. • Improved Depth & Sensitivity over the Advantage Series • Improved Stability • Water-proof to 1 Meter • Resin Encased Spiral Wound Litz Winding • Unique Solid Housing – Strong, Rigid & Lightweight • New Smooth Surface Skid Plate with tapered edges for longer life & quieter operation • Polycarbonate Shaft Mount • Gold Plated Plug • Compatible with Minelab GPX, GP & SD series gold detectors • 3-Year Warranty
