Search coils made by Detech Ltd

Search coils made by Detech Ltd 

most popular & wanted search coils in the world

The first models of coils are the 14” EXcelerator coils for Minelab’s Explorer and Sovereign detectors. For their make is used one of the patented technologies of the company. The housings are made by hand from chopped-strand material and polyesther resins. Thus the housings are light and very strong, but the process of production is too slow.  This forces the purchase injection moulding and vacuum thermoforming machines in the next years, as well as the make of steel moulds for new housings. In this period the company receives 5 patents in the field of metal detectors and searchcoils for them. Detech Ltd is the first company in the world, applying searchcoil with built in magnetic sensors in the middle sector. This allows perfect discrimination of the ferrous objects by the PI detectors.

Trying to escape the stereotype of the round coils in 2006 the company releases a new, revolutionary type of coil on the market – S.E.F. (Symmetrical Electromegnetic Field) coils, known also as Butterfly coils. These searchcoils combine the advantages of both DD and Concentric coils:

The S.E.F. Butterfly search coils offer better ground balance, more stable operation in all conditions, even deeper in the ground, and more accurate target identification

All our coils are made using high quality materials. The housings are made of UV protected material. Their inner side is covered with chopped-strand material for a better shock resistance. We use resins, which are “transparent” for the electromagnetic waves, and perfect shielding. The coils are water resistant, and operate in a wide temperature range.  The searchcoils are standardly equipped with excellently fitting cover, and have two years full warranty.
