underwater acoustic modems trans- port more than 95% of the world's acoustic communication data. These systems have set a series of technical performance records in field deploy- ments all over the world. LinkQuest's line of TrackLink Acoustic Tracking

Systems provide highly robust, accu- rate and cost-effective Ultra Short

Baseline (USBL) solutions.The

FlowQuest Acoustic Current

Profilers, FlowScout Acoustic Flow

Meters and NavQuest Doppler

Velocity Logs (DVL) were designed to provide solutions for current pro- filing, wave measurement, flow meas- urement or precision underwater nav- igation applications. These products offer significantly longer range with high accuracy. LinkQuest also manu- factures PinPoint LBL acoustic posi- tioning systems and Precision Marine

Imagenex was founded in 1988 by pioneers in the development of high-resolution imaging and profiling sonar.

Within two years the company had produced its first sonar– an imaging head for the commercial underwater indus- try that was the unheard-of size of a coffee mug and rated for 300m depth. Company milestones include introduc- ing the first digital color imaging sonar that could be operated from a computer without a dedicated processor in 1995; introducing a sidescan sonar in 2000 with a revolutionary price/performance ratio; and developing a high qual- ity, compact and cost-effective multibeam sonar with obstacle avoidance or profiling configurations and optional depth ratings to 6,000m. It is the company’s development of the lightweight, cost-effective Delta T multibeam sonar unit that is successfully bringing the benefits of real-time, high-resolution, 3D visualization within reach of operators that previously had to settle for mechanical scanning single-beam devices. The combination of reduced cost, high quality imaging and functionality of the Delta T and other Imagenex products has been increasing its popularity in the scientific market, and for commercial, recreational and search and rescue (SAR) applications around the globe.

Imagenex’s patented Delta-T multibeam system is in use around the world on many different types of vessels, includ- ing AUVs operating to 6000m water depth. Used extensively on pipeline inspections and seabed mapping projects, these systems have a major impact on the prevention of marine disasters. New additions include the model 965

Multibeam Imaging sonar is the result of applying recent advances in computing power, which makes it possible to transfer and process the data at resolutions equal to that of computer monitors, with frame rates up to 10 per second.

The new Model 878 "RGB" Sidescan Sonar is the next generation in high resolution sidescan sonar. The unit runs three simultaneous sonars on each side at different sound wavelengths, providing enhanced image clarity and now, for the first time, the ability to discriminate targets based on their acoustic "color."
