The Insight-240 forward looking multibeam sonar images with an entire 90-degree sector on every ping. This video-like capability is ideal for all-condition navigation, target location, tracking, and general situational awareness.

SKU: N/A Category: Tag:


The Insight-240 forward looking sonar features multibeam technology to image a full 90 degree sector with every ping. This video-like capability is ideal for all-condition navigation, target location and tracking, and general situational awareness.

You can observe echos from objects like ropes, walls, dock pilings, shipwrecks, boats, fish, and any other structures or objects that reflect sound waves. The generated image provides a compelling reference for navigation regardless of water visibility, allowing for the localization of essential features quickly.

The Insight-240 is a 240 kHz, 150m range, 300m depth rated system. For general purpose applications, a mounting bracket incorporating a servo tilt mechanism is highly recommended.
