SONIC 2026

Enjoy the latest advanced technology giving you versatility, productivity and performance – that’s what the Sonic 2026 Broadband Multibeam Echosounder delivers.

The latest advanced technology, with versatility, productivity and performance – that’s what the Sonic 2026 Broadband Multibeam Echosounder delivers.

 Major components include:

  • A compact projector, receiver, and a small dry side Sonar Interface Module.
  • The extremely low power draw of 75W makes it possible to operate the system on vessel battery power.
  • Focused 0.45° x 0.45° beamwidths with up to 800m+ or more sounding depths*
  • Optional 90kHz/100kHz operation for extended range coverage.

Unlike other commercial shallow water multibeam echosounder systems, R2Sonic’s sonar processing is embedded in the receiver, dramatically increasing system efficiency and simplicity in integration.

The compact size, low weight, low power consumption and elimination of separate topside processors makes the SONIC 2026 system well suited for small survey vessel or ROV/AUV operations.

Basic mounting hardware is supplied as standard with each system, including dual head mounting brackets.

System Options

Integrated Inertial Navigation System

The Inertial Navigation System (INS) integrates seamlessly with the Sonic MBES enabling the user to obtain the most accurate and robust motion compensation solution for hydrographic surveying encompassing vessel latitude, longitude, altitude, heave, pitch, roll and heading.

TruePix™ Backscatter

Many multibeam systems are capable of recording data on acoustic backscatter ‒ artifacts that may interfere with the accuracy of depth soundings. Only R2Sonic provides TruePix™ –  a process that is independent from bottom detection, and like Digital Side scan, can be used in data editing to determine whether the data points are outliers or real.

Raw Water Column Data

Raw beam formed water column data output provides increased functionality for Sonic Wideband Multibeam Echo Sounders with the ability to collect simultaneous and co-registered bathymetry, backscatter and water column backscatter data for variety of applications including pelagic fisheries habitat mapping, methane seep investigation and more.

3000m Immersion Depth Rating

Sonic Wideband Multibeam Echosounders are available with 3000m immersion depth rated option for ROV/AUV applications. For 3000m rated systems, extensive pressure testing is performed to just over 300bar and supplied with pass rating certificate to ensure performance to specified depth. Systems are typically pressure tested at time of order but can also be upgraded at any time with return of unit to R2Sonic facility.

Mounting Hardware & Assemblies

Basic mounting hardware is supplied as standard with each system. A lightweight and easy to assemble mounting bracket and fairing is supplied as an option. The Sonic mount bracket & fairing is designed to reduce cavitation around the receiver array and includes a protective fin for the transmit projector when mounted in the fore position.

Antifouling Coating Protection

Barnacle build up is a bane to many customers who incorporate high value acoustic sensors to vessel hull. In some environments build up can be severe, blocking the active sensor components effecting performance and requiring expensive dry docking and labor hours to clean. R2Sonic offers a unique non-ablative, non-toxic, antifouling coating protection option for Sonic Wideband Multibeam Systems.

    “The Sonic 2024 Wideband Multibeam Echosounder was quick and simple to integrate into our AUVs and along with the accuracy and stability of an AUV platform produced excellent results. The ease of integration, reliability, quality and resolution, increased useable swath coverage and low power consumption makes the system a suitable replacement for ageing AUV Multibeam systems.”

    “Speedy delivery is essential to us. Thanks a lot for your excellent service and understanding of our situation.”
    - Bente Rosell Rask, Account Manager, Rental & Personnel
    “We have used the Sonic 2024 for surveying a rocky slope in the Brest Port, for which reference terrestrial laser scanner data is available. We found the Sonic 2024 returned exceptionally clean data, even on difficult seabed such as dumped rocks. We think this system will dramatically decrease the data cleaning effort for digital terrain models production.”
