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.
