SEF DD searchcoils to suit Minelab GPX, GP and SD Machines

All  Detech coils are made using the highest quality materials. The housings are made of UV protected material, their inside is covered with chopped-strand material for a better shock resistance.  We use resins, which are “transparent” to the electromagnetic waves, and offer  perfect shielding.  The coils are water proof and operate in a wide temperature range.  The searchcoils are all equipped with an excellent fitting cover, (skid plate) and have a two year full warranty.  Excellent equipment for Detech Metal Detecting in Australia, suited to Australian prospecting conditions
