1. PI Advantages:
The pulse induction is very effective in detecting deep underground.
Ability to handle highly mineralised ground, undisturbed searching in mineralized soils and salt water.
A pulse detector is best for salt water beaches and diving.
Good sensitivity to gold.
2. PI Drawbacks:
Regardless of their sensitivity they have two or three essential disadvantages. Their battery utilization is substantial because of the force required by the beat transmitter, and they are very sensitive to even modest ferrous items. Their utilization is therefore basically confined to shoreline seeking, where items are liable to be covered at extensive profundities, and where huge openings can be effectively and quickly burrowed. On inland locales, their users can get to be debilitated by the continuous diving of extensive openings in hard ground to recuperate corroded nails!
