Combining a resolution twice that of other mechanical sonars, and an ultra-narrow horizontal beam angle, the dual frequency
SeaKing Hammerhead is a truly versatile survey sonar. To complete the package a fully integrated attitude sensor and compass are included to enable accurate logging of survey data.
Two standard configurations are available, either as a pressure only package (SeaKing 701) or as a pressure, conductivity and temperature package (SeaKing 704).
The sensors form an integrated package, however, the PA500 altimeter is on a cable and can be mounted separately on the ROV which allows positioning of the individual sensors away from areas of masking or disturbance such as vehicle structure or thruster wash.
The unit may be mains or DC powered; if mains powered then a DC output is available to power connected equipment. If DC powered the output DC is a fused extension of the input supply.
Front panel diagnostic LEDs show interface ports in use and their status. The SeaHub is fully compatible with Tritech Seanet Pro software suite and is automatically recognised in Windows if Seanet Pro is installed.
OEM configurations include, for example, low magnetic signature rigid Delrin™ (Plastic) housings or supplied with a right-angled transducer.
Output for the PA200 or PA500 can either be simultaneous analogue and digital outputs, allowing them to be interfaced to a wide range of PC devices, (including operated through Tritech’s data acquisition and logging software, Seanet Pro), data loggers, ROV telemetry systems and multiplexers.

As well as providing RS232 output the Multicomm can act as a transparent interface allowing communication using Tritech’s ARCNET protocol.
The Multicomm can also accept inputs from third party sensors, such as a gyro, which would be connected to the Multicomm AUX port.
The Gemini NBI produces an acoustic image, cutting through the water with a narrow acoustic beam and at the high refresh rate offered from the Gemini range of multibeam sonars. Based on the proven design of the Gemini 720i, the Gemini NBI uses a 1° vertical beam instead of the 20°vertical beam found on the 720i.
This reduced beam width allows the user to more precisely identify the position of the acoustic targets than is possible with a wide beam imaging sonar which is commonly used for obstacle avoidance operations.
