LinkQuest Inc. is a leading manufacturer of precision acoustic instruments for offshore oil exploration, construction, drilling, survey, environmental study and other oceanographic applications. Our innovative Broadband Acoustic Spread Spectrum (BASS) Technology sets new standard for acoustic communication and positioning. LinkQuest’s FlowQuest Acoustic Current Profilers and NavQuest Doppler Velocity Logs provide highly competitive solutions for current profiling or precision underwater navigation applications. LinkQuest Inc. is the only company in the world capable of producing sophisticated underwater acoustic modems, USBL tracking systems, acoustic current profilers and Doppler velocity logs. Over years, LinkQuest has earned an extraordinary reputation in terms of product performance, product quality and customer support.

LinkQuest is the dominant supplier of underwater acoustic modems in the world. Its SoundLink High Speed Acoustic Modems transport more than 95% of the world's acoustic communication data. These systems have set a series of technical performance records in field deployments all over the world. The SoundLink acoustic modems have formed the world's largest underwater acoustic communication networks with hundreds of nodes.

LinkQuest's line of TrackLink Acoustic Tracking Systems provide the world's most robust, accurate and cost-effective Ultra Short Baseline (USBL) solutions. The TrackLink systems are the world's best selling USBL tracking systems.

FlowQuest Acoustic Current Profilers
are ideal for measuring currents and flows in oceans, harbors, lakes and rivers. With its capability for significantly longer range, standard deepwater depth rating and seamless integration with third-party sensors and LinkQuest acoustic modems, the FlowQuest system is not just a current profiler but also serves as a focal point for underwater deployments.

NavQuest Doppler Velocity Logs (DVL)
are ideal for precision navigation and positioning of underwater vehicles. With their capability for fast and accurate velocity output, significantly longer range and smaller minimum altitude comparing against similar products, the NavQuest Doppler Velocity Logs are the excellent choices for underwater precision navigation applications.

LinkQuest's PinPoint LBL Acoustic Positioning Systems are highly accurate and robust. These long baseline positioning systems excel in narrowly confined, long-range shallow water and noisy environments.

LinkQuest's Precision Marine Geodetic System is the world's only commercial acoustic positioning system capable of better than 0.5 cm in accuracy. These systems have been extensively deployed for Tsunami and earthquake monitoring and prediction.
