882-GS Imaging
Gyro-stabilization makes the high resolution 882-GS sonar capable of crystal clear visualization of the ocean environment from moving platforms, no longer compromised by the blurring effects of host vehicle rotation. An advanced, low drift gyro is integrated directly into the sonar head, so the sonar can compensate for vehicle motion in real time with unprecedented accuracy, stability, and robustness.
Using Ethernet communications, this all-in-one, high performance digital imaging sonar exceeds 100 shots per second on short range at up to 2 mm range resolution, and can auto-adjust acoustic frequency and resolution to scan up to a 100 m radius, 360° surrounding area.
The Model 882-GS has low power, simple set-up, and small size that make it an ideal tool for large work ROV’s and small inspection vehicles. On it’s own it is an amazingly simple drop sonar and borehole inspection package: just add a laptop computer and power supply and run the included Imagenex software.
