Coda Octopus Group, Inc. announced the launch of the first product within its fourth-generation range of sonars, the Echoscope4G Surface. The patented Coda Octopus Real Time 3D sonar is the only commercially available real-time 3D sonar that uniquely enables vision, mapping and measurement in real time in low or zero visibility conditions underwater. Known industry-wide as having the sonar products for multiple applications, Coda Octopus's next-generation launch (4G) is a new, proprietary and scalable breakthrough for the Company that is built upon 25 years’ experience leading the field. This first product within its 4G range, Echoscope4G Surface, is designed for nearly plug-and-play ease of use for shallow water operational needs not to exceed 20 meters (66 feet) water depth. The Surface features a significantly smaller form factor that is 50% lighter and 40% smaller and requires 30% less power than that of the Echoscope 3G product line all without compromising real-time 3D image and mapping fidelity, performance or capability. These are important application attributes for the subsea market, as subsea vehicles become smaller and lighter. Whereas the third generation was more compatible with the likes of work-class remotely operated underwater vehicles (ROV) and other vessels, Coda's reengineered and repackaged 4G range expands the technology to a broader number of market applications. The Echoscope4G Surface is available in single, dual and XD triple models, offering three independent frequency and 3D volumes to give Coda's customers a flexible choice for a wide range of target applications. This range in performance of real-time 3D sonar enables tasks from ultra-high-resolution inspection to wide-area mapping from a single, lightweight and easy-to-deploy sensor. Built around Coda Octopus's patented technology, the Echoscope4G Surface generates a complete 3D model, composed of over 16,000 soundings, from each and every acoustic transmission, and up to 12hz refresh rate. The Surface is neutrally buoyant in water, and features a rugged metal housing for harsh conditions and a fully integrated handle and mounting points for attaching to vessels. Further, this debut 4G product is compatible with the full range of Coda Octopus proprietary 3D software and accessories. The Surface has undergone extensive regression testing and has two select customer trials underway. Designed for optimum task performance in shallow water, product applications include port and harbor security, law enforcement search and rescue, infrastructure inspection, underwater construction, dredging and rock dumping, and breakwater block placement. The previous third generation of Echoscope® technology has been used extensively in coastal management to create safer harbors and inshore protection, and reduce coastal erosion. The patented technology allows breakwater operators to visualize and track thousands of interlocking blocks into position in real time, to ensure every block placed is aligned so the integrity of the entire structure is stable.
