The TriTech Multibeam Imaging Sonar offers a world-class data 97Hz data update rate at 1M, CHIRP (Compressed High-Intensity Radar Pulse) processing to ensure high resolution at long ranges, and an integrated velocimeter to supplement sonar feedback.

Low-visibility operations

Cameras and diver’s eyes often are unable to effectively search due to poor visibility underwater. An imaging sonar is the best tool to then reidentify the target, since oftentimes side scan data does not produce an exact location (so navigating back to the potential target can be difficult). Once the target is reidentified, the sonar can be used to continue to track the target as you move closer, and when you get close enough, it can even be used to perform the visual verification.

Sonar for search and recovery

In Search and Recovery operations, First responders looking for evidence or drowning victims typically sweep an area using side scan sonar, identify potential targets and then investigate those targets to see if it is in fact the victim.

Sonar for hull inspection

In inspection operations, particularly in murky water applications, it can be difficult to use just a camera to get an understanding of the condition of a structure.

For example, when inspecting the hull of a ship, you want to see if there are any major defects or corrosion, damage to the coating, zincs, anodes, propeller, check the coating condition, check if the hull needs to be cleaned.
