The 881A-GS and 881L-GS High Performance Gyro Stabilized Imaging Sonar.

Gyro-stabilization of the Imagenex Model 881L-GS and the 881A-GS makes these high resolution sonars into a systems capable of crystal clear visualization from moving ROVs without the blurring effects of host vehicle rotation. An advanced, low drift gyro is integrated directly into the sonar head, so the sonar can now compensate for vehicle motion in real time with unprecedented accuracy, stability, and robustness.
The enhanced capabilities of the 881L-GS and 881A-GShave not compromised the performance of the sonar. Using Ethernet communications, these all-in-one, high performance digital imaging sonar can still exceed 100 samples 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 200 m radius, 360į surrounding area.
The Model 881L-GS and 881A-GS feature low power consumption, simple set-up, and small size that make it an ideal tool for large work ROVís and small inspection vehicles. It is also a powerful and convenient drop sonar and borehole inspection package: just add a laptop computer and power supply and run the included Imagenex software.


The NEW 878 High Resolution Towable Sonar.

Simultaneous dual frequency, high resolution, LAN compatible with built in GPS, track plotter, and optional orientation module including depth,temperature, pitch, roll and heading sensors.  Also available with optional echo sounder.

The SportScan Dual Frequency Sonar        The Yellowfin Triple Frequency Sonar


The Sportscan is an economical scanning sonar system is available in single frequency and dual frequency models.  A deeper water version, the Yellowfin, is also available.

The Sonar Bell Sonar Target:

SonarBell in operation

SonarBell operates by focusing and reflecting sound energy back to its source, much as a lens or mirror can focus light. Just like a lens or mirror SonarBell is a completely passive device.


By focusing and re-radiating the sound energy back in the direction from which it came a 200mm SonarBell can deliver the same sonar target strength as a 2m diameter metal plate whilst being relatively light weight and easy to handle.


In contrast to other technologies used for the location of assets SonarBell does not suffer from the intermittent reflection of corner reflectors nor does it require the battery replacement cycle of transponders.


Digital Edge DVD

The Digital Edge System allows you to record video and overlay with a sophisticated but easy to use interface.  The final product is a customer-deliverable hard disk.
