Furuno CH-250 Searchlight Sonar


The CH-500 searchlight sonar is the first of its class to have integrated motion sensors.



This CH-500 sonar is one of the most comprehensive and fastest sonars of its kind. It provides 6 selectable step variations (6°,12°,15°,18°,21° and 24°) for high scanning speed that can cover sectors widths from 24° to 360° in a couple of seconds. Thanks to its high training speeds, the CH-500 can rapidly scan a large area providing the ultimate fishing and navigational experience.
