4. Structure of the instrument

Metaldetector consists of five parts: 1.coil, 2. rack, connecting the coil to the electronic block,

3. electronic block, 4.arm support и 5.battery box.

Standart coil

Standart coil of Golden Mask 3+ is with size 10.5" (26.5cm) DD. The construction of coil is

plastic- ABS , and at the bottom is overflowed with epoxy resin, which creates more strength

and hermetic sealing of the entire structure. Coil has a good sensitivity to both small and large

objects to.

Additional coils

DD 12.5" (32см) 15"(38см).

Coils of small dimensions have better sensitivity for small objects (coins) and they are

prefered to operat in highly polluted areas.The large drills(DD32,DD38см) have better

sensitivity to large objects, suitable for quick search of buried objects and they have 10-20%

better sensitivity than DD 26.6 сm.

rack

The rack is made of aluminum tube, which at the bottom to the coil is made of Carbonic (not

metal), so it won’t hinder the work of the drill.
