How it differs from its neighbors
Fisher's CZ-21 is a diving detector with a hip-mountable control box. Its spec sheet lists it as fully submersible to 250 ft, and also prints IP54. It runs 5 and 15 kHz simultaneously and weighs 5.69 lb, against the PulseDive at 19.4 oz.
The pinpointers on file are rated for shallower water. Garrett rates the Pro-Pointer AT IP68 to 20 ft (6 m). Nokta rates its own AccuPOINT IP68 to 10 ft. Both are made to find a target once a detector has signaled it.
For wireless audio, the PulseDive has a built-in wireless module for Nokta 2.4 GHz Green Edition headphones. It measures 17.7 in (45 cm) long. The warranty is 2 years.
