earthSCAN 

Nokta RS Pinpointer will detect targets right on the spot. Hand-held detectors have proven to be extremely effective in locating coins

and rings in piles of dirt and sand dug by detector users. When a coin has been in the ground for years, the oxidation often turns the

coins color the same as that of the surrounding dirt, making it very difficult to see. If you are spending more time checking the dirt

from the hole and continuously checking the hole you are losing very valuable detecting time. Instead of detecting more treasure,

you're spending more time locating a target that could be found very quickly with a hand-held detector.
