PulseDive Scuba

The Nokta PulseDive Scuba Detector is a hand-held pulse-induction machine built for the water. Its sealed IP68 body carries a manufacturer rating for submersion to 60 m (200 ft) — deep enough for genuine scuba work rather than just wading — and its 3 kHz pulse circuit ignores saltwater, wet sand and black-sand mineralisation, the conditions that unsettle VLF detectors. The supplied 20 cm (8") scuba coil gives real sweep coverage for rings, chains, coins and dropped metal, while the complete unit measures 45 cm and weighs 550 g with the coil cover fitted, so it swings one-handed and clips to a BCD, belt or wrist. Operation is deliberately simple for gloved hands and poor visibility: three alert modes — audio, vibration, audio + vibration — plus a red LED that flashes faster as you close on a target, five sensitivity levels, a one-press rapid retune and 40 steps of frequency shift to escape another detector working nearby. Dive Mode locks the keypad so water pressure cannot change your settings at depth, an LED flashlight lights the recovery hole, and a lost alarm beeps and flashes after five minutes of inactivity. Power comes from an internal 1650 mAh lithium-polymer battery charged over USB in about two hours, and a built-in 2.4 GHz module pairs with Nokta Green Edition wireless headphones (sold separately). Note that the 60 m figure is a submersion rating, not a detection range: this is a short-range water probe for recovery work, not a deep-seeking prospecting detector, and the 14 cm (5.5") pointer coil that converts it into a pinpointer is an optional extra.
