This Detech 21 x 17″ S.E.F Butterfly Search Coil is for use with the Minelab Explorer, E-Trac, Quattro, And Safari metal detectors. The 21×17″ S.E.F, or butterfly coil is designed to offer better, all-around performance when compared to the other DD coils on the market today. This New range of S.E.F – Symmetrical Electromagnetic Field Coils is a new patented technology. With over three years of research and development, they offer greater stability and depth over similar-sized search heads. The advantage of this coil is its stability. This means sensitivity can be increased to give greater depth. The average depth increase is reckoned to be 10% – 15% depending on ground conditions. By upgrading to this coil you will achieve the best depth and most accurate pinpointing. All Detech search coils are produced using the highest quality materials and the 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 shock resistance. The materials are “transparent” to the electromagnetic waves and provide perfect shielding. The coil is UV and waterproof and operates in a wide temperature range. The coil comes standard with a coil cover.
The Detech S.E.F coil has the following advantages:
- Ribbed housing, specially designed for absorbing 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
- Better Sensitivity
- More Accurate Target Identification
- More Stable Ground And Better Overall Field Performance
- Better pinpointing
- Deeper detection depth
