Anyone who detects in streams and underwater should consider the Nokta Pointer Pinpointer. It is fully waterproof and can be submerged to 1 meter (3 feet) for 30 minutes at a time! Professional performance is in the design; Nokta Pointer features 10 levels of sensitivity control, a bright LED light and “Lost” alarm with auto shut-off. Target alert options include audio, vibration or both. And what REALLY sets the Nokta Pointer Pinpointer apart is the included bonus kit: 2 hard shell cases (1 with scraping blade), carrying pouch, finds bag, belt holster and 9-volt battery. This is pinpointing to the extreme!
