The pulse induction is very effective in detecting deepunderground.
Ability to handle highly mineralised ground, undisturbedsearching in mineralized soils and salt water.

Good sensitivity to gold.
Regardless of theirsensitivity they have two or three essential disadvantages. Their batteryutilization is substantial because of the force required by the beattransmitter, and they are very sensitive to even modest ferrous items. Theirutilization is therefore basically confined to shoreline seeking, where itemsare liable to be covered at extensive profundities, and where huge openings canbe effectively and quickly burrowed. On inland locales, their users can get tobe debilitated by the continuous diving of extensive openings in hard ground torecuperate corroded nails!
