Overview

The Echoscope® Diver Survey Sled NANO (EDSS NANO) is a new variant of our neutrally buoyant and highly maneuverable survey sled, which benefits from the reduced form factor of the Echoscope PIPE NANO Gen Series^® sonar, and a completely re-designed tactical buoyancy set, making it easier than ever to handle underwater.

At the heart of the platform sits out cutting-edge real-time 3D imaging sonar, the Echoscope PIPE NANO Gen Series^®, which generates high-resolution real-time 3D images of its environment. These are georeferenced using a customer-selectable subsea Inertial Navigation System, enabling it to produce accurate models and maps which are available to the user immediately. Its easily adjustable mounting plate allows it to switch from generating detailed imagery of ships’ hills to providing IHO-grade surveys of the seabed, making it a highly flexible multi-application package.

Echoscope PIPE NANO Gen Series^® is our AI-ready, ultra-compact family of real-time 3D volumetric imaging and perception sonars — purpose-built for the next generation of underwater vehicles, diver wearable systems, and robotic platforms. Equipped with AI-enabled perception and autonomy capabilities, it converts real-time 3D acoustic data into navigational awareness and intelligent system response. Its reduced form factor and minimal weight make it ideally suited for diver controlled deployments, delivering exceptional underwater spatial awareness and bulletproof performance in zero-visibility conditions. The result is greater operator confidence, enhanced mission effectiveness, and reliable performance in the most challenging subsea environments.

PROBLEM - SHIP HULL SCANNING

Across the globe, port authorities and law enforcement agencies shoulder the vital task of detecting contraband hidden on mule vessels and uncovering parasitic packages attached to larger ships. In challenging underwater environments, where visibility is often murky or non existent, inspections typically rely on cameras followed by manual diver checks of the hull. This approach not only increases the risk of missed threats but also places divers in hazardous situations, requiring direct contact with potentially dangerous targets.

Solution - Echoscope^® Diver Survey Sled NANO

The EDSS NANO is a compact and ergonomic, diver controlled solution that provides fully geo-referenced, high definition real-time 3D imagery allowing full environmental awareness in all water conditions, including zero visibility. This portable solution allows for quick deployment and accurate data collection in a variety of applications including ship hull ship scanning to identify parasitic packages or potential threats.

PROBLEM - SEARCH & RESCUE

Law enforcement agencies around the world are often faced with the task of finding and recovering objects underwater in a wide range of circumstances, from criminal investigations to humanitarian disaster relief. Performing manual fingertip searching is time-consuming and both physically and mentally fatiguing; the logistics of tracking exactly where has been searched, and whether any areas were missed, presents an additional challenge.

Solution - Echoscope^® Diver Survey Sled NANO

By combining accurate position and attitude navigation with the Echoscope PIPE NANO Gen Series^® sonar imagery, the EDSS Nano allows a diver to produce accurate, detailed and reliable models of wide areas. Complete coverage is assured, and data can reviewed and processed in our 4G USE® software, allowing imagery, measurements and 3D point cloud data to be exported for reporting purposes.

PROBLEM - UNDERWATER SALVAGE

Divers involved in salvage operations have to tackle complex, unstable and frequently changing environments, often with severely limited visibility. They face hazards such as entanglement, disorientation or entrapment, and work on target structures that are likely to be unsound and inherently dangerous. Even areas which have been surveyed or inspected before can present unknown challenges as seabed sediment or the target structure itself shifts over time.

Solution - Echoscope^® Diver Survey Sled NANO

The easily maneuverable EDSS NANO allows divers to approach a structure safely and build a 3D model of its current state in real time. It can be moved freely allowing structures to be viewed from all angles for complete scene awareness. Information is available in real time to the diver and also on the surface, allowing for rapid decision making and safe operations.

By integrating the high-performance, ruggedized DPPmax, operators can integrate DAVD Flex functionalities directly into their EDSS NANO configuration through a Head-Up Display integrated into the Diver’s helmet or face mask. The DAVD Flex integrates topside control, a Head-Up Display (HUD), and digital communications for divers, facilitating seamless real-time information exchange between divers and supervisors via augmented reality displays in the diver’s helmet or mask. Supervisors use the Coda Octopus 4G USE® DAVD Flex Edition software to manage the HUD, displaying real-time 3D imagery and communicating with divers through images, videos, technical drawings, and messages. Divers access critical technical data and support from surface teams, optimizing mission outcomes with features like realtime depth, compass, head tracking, dive timers, alerts, positioning, navigation, and enhanced audio capabilities. Traditional diver audio communications can be challenging in the best of conditions, but are the primary form of communication between the diver and the supervisor. DAVD Flex opens the gateway to a new era of digital diver communications with the surface, providing a number of critical features including auto-noise cancellation and background noise suppression. These functions provide clear audio communications even with background noise at either the diver or on the surface. Recorded speech, videos with audio tracks and automated computer speech instruction are output digitally from the DPPmax on the diver in crystal clear audio.
