The coil comes standard with coil cover.
Compared with the classic DD coils it has the following advantages:
Ribbed housing, specially designed for absorbing the 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.
