With joy and pride we would like to introduce a new product: MAS DD 13,5” search coil. The waterproof coil has been produced in Poland (in EU) in cooperation with recognised resins and wire manufactrers using the latest technologies.

Many tests we have done, proved that using the MAS DD 13,5” search coil will improve the sensitivity and depth of your metal detector. Depending on the model of the metal detector it would give you extra 20-50% when comparing to the standard search coils.


We carefully worked on the design of the coils shape to get the best parameters in our MAS DD 13,5” search coil.

Each of the coils is manually tuned to ensure you get the most out of it. The unique shielding technology of the tailor-made coil cable reduces false signals, making it possible for the metal detector to work in more sensitive mode, thus increasing its depth.


Metal detecting coil is constantly exposed to contact with stones, rocks or tree roots or branches, thus must be tough and really resistant to damage. The housing of our coils is made of solid UV resistant ABS plastic with 2 mm thick wall. The special resin filling makes it even harder and impossible to damage whilst normal use. The filling we use is not only lighter but also more resistant in comparison with resins normally used as fillings in coils of other makes. Tailor-made coil cable for our MAS DD 13,5” search coils, covered with special shielding, gives additional protection against false signals and is designed for constant work ( twistning around the stem), making it more resistant to damage.


Cooperation with resins manufacturer resulted in creating new epoxy resin formula for filling the coil housing. Thanks to it the coil is more resistant to extreme weather and temperature conditions.
