RESEA is a 4-input underwater acoustic recorder designed to enable PAM operators, Marine Mammal Observers (MMO) and Protected Species Observers (PSO) to implement powerful post-processing monitoring (up to 500 kHz bandwidth; over a 100 dB dynamic range).

SYLENCE-LP underwater acoustic recorders allow cost-effective and reliable acoustic monitoring with best value for money on the market (256 kHz max bandwidth; dynamic range of over 100 dB). 2 models are available: one 22-cm-high version (one fixed hydrophone, 35 days of non-stop recording) and one 44-cm-high version (one fixed or cabled hydrophone, up to 180 days of non-stop recording).

TRIPOD is a seabed hydrophone structure hosting 4 hydrophones and one RESEA underwater acoustic recorder. In this regard, it can be used as a simple deployment frame, but also allows for trajectography and sound propagation analysis. TRIPOD is lightweight, easy to use and can be easily deployed by a single person. The whole device naturally lands in an upright position on the seabed.

RUBHY is a Wi-Fi remotely-controlled buoy offering a range of applications in the field of underwater noise measurements. It acquires data from 4 wide-band hydrophones and simultaneously sends and displays real-time noise information such as SEL, SPL and 3rd octave band levels within a 10 km range. This is a robust buoy particularly suited to offshore conditions that is an excellent solution for autonomous real-time noise surveying of harbor construction, pile-driving operations and seismic surveys. With less than 350 kg, it is easily deployed and recovered from a working boat. Rugged buoy RUBHY can be deployed for real-time studies (up to 40 days of non-stop recording) in rough seas (up to sea-state 5). Many options are available and additional sensors can be added.

REMHY is a Wi-Fi surface buoy that leads the way to a new range of application for underwater noise measurements. It can simultaneously acquire data from 4 wide-band hydrophones of variable cable length. This buoy accepts both passive and preamplified active hydrophones and its wide band analog input allows up to 1 MHz with a dynamic range greater than 100 dB therefore guaranteeing an efficient signal to noise ratio. The embedded digital signal processor allows high speed acquisition filtering while users can stream data and launch or stop recordings up to a distance of 700 m. REMHY can be easily deployed and recovered by a single person.

COSTOF2 is a one-of-a-kind multisensor datalogger developed jointly with Ifremer for surface or deep sea oceanographic purposes (down to 6000m). COSTOF2 can host numerous sensors with up to 12 sensors able to work simultaneously, supporting various protocols such as Ethernet or RS232/ 485/ 422.

COMET-300 is a state-of-the-art AUV featuring advanced navigation and detection capabilities. Keep an eye on COMET-300 from the surface thanks to its communication system capable of displaying real-time position and navigation data. Several AUVs (up to 10) can operate as a swarm using Sparse-LBL localization while combing wide areas geared with side-scan sonars and diverse payloads.

NemoSens® is a small, lightweight µAUV perfect for scientists and offshore companies in search of a modular ally. Easy to deploy at any time, payloads are simple to add while users can take full ownership of NemoSens® thanks to its open Linux architecture. NemoSens® offers long-lasting endurance (over 8 hours at 4 knots) and is easy to recover.

The COMET MCM AUV has been specially designed to assist EOD divers in operations. Interacting with Surface Communication Modules (SCM) and Positioning & Relay Beacons (PRB), COMET MCM brings its own navigation features (GPS, INS, DVL, swarm mode) and payloads (side-scan sonars, magnetometer… ) to the mine warfare scene, while acting as relay or LBL positioning beacon.

The diver-held Sonar and navigation system SONADIVE is a turnkey solution for EOD divers seeking safe and covered MCM operations. SONADIVE features a 12″ backlit screen for maximum visibility and lowest magnetism on the market with hot-swappable lithium-ion batteries. Detection capacities feature BlueView sonar paired with an HD camera while navigation is provided by GPS, INS and DVL. In addition underwater acoustics allow real-time exchange of text messages, position and navigation data. The communication range can exceed 2000 m between two devices and be extended to over 5000m using relay beacon.
