Sonar Screensaver is a flexible and detailed fabulous sonar simulation software. It will turn your PC into a fabulous sonar outpost, watching for the objects ar surface and underwater in some coastal zone.

Its main display is a large circular screen with famous rotating beam. There are displayed all detected objects, ocean and terrain noises, contour map and grid marks. Every detected object can be supplied with a marker – small box with brief object information, like class, identifier, movement direction and velocity.

There will be also other displays with special information like current sonar detector state and location, list of detected objects, acoustic channel bar graph display, identification system reports and log with all events occurring with detector.

Sonar screensaver can produce many sounds, like emitter sound (well known "sonar beep"), whales and dolphins songs, underwater noises and sounds from screw propellers of the ships and boats floating near the sonar detector.
