Abstract
An acoustic search device comprises an ultrasonic transducer with a plurality of elements for transmitting acoustic signals toward a viewed search area and for receiving echo signals therefrom, a display, an electronic unit and an optical viewing device. The electronic unit controls the transducer and the display which shows a display image of the viewed search area based on the echo signals reflected from the viewed search area. The display image is seen by means of the optical viewing device. The optical viewing device, the display, and the ultrasonic transducer are arranged to form a part of the protective cap of a diver and are situated in a protective cap, substantially in succession in the direction of sight of the diver.
