Overview
The CZ-21 is a professional underwater detector. It transmits 5 kHz and 15 kHz at the same time, which gives reliable target analysis in salt and fresh water and in mineralised beach sand.
Three-tone audio ID tells iron, foil and coins or jewelry apart without looking at the box, and saltwater compensation and audio boost help with faint targets. The housing is rated to 250 ft, the waterproof headphones are permanently attached, and four 9V batteries run it for up to 55 hours.
