18″ DD Closed design
By upgrading to this coil you will achieve the best depth and most accurate pinpointing. Compared to traditional DD coils, the patented Ultimate coil technology provides you with a more stable operation, better ground balancing, and the most accurate target identification. All Detech search coils are produced using the highest quality materials and most advanced manufacturing techniques. The coil is filled with the latest lightweight resins strengthened with glass fibers and a chopped strand material for the best in shock resistance. The materials are“transparent” to the electromagnetic waves and provide perfect shielding. The coils are UV and water proof and operate in a wide temperature range. This coil comes standard with coil cover, with a system for secure doing-up.
Compared to a standard Double D search coils, the patented Ultimate coil design has the following advantages:
Ribbed housing, specially designed for absorbing the mechanical shocks and vibrations, made of special polymer, strengthened with glass fibers, injection-molded with very high pressure, with maximum UV protection. The coil keeps its perfect inductive balance in a very wide temperature range.
Better ground balance
More Stable Operation
More Accurate Target Identification
More Stable Ground And Better Overall FieldPerformance
Deeper detection depth
