SONIC 2024

The highly recommended Sonic 2024 Wideband Multibeam Echosounder represents the latest in advanced modern system design and architecture, providing unprecedented system versatility, productivity and performance. The 2024 truly sets the standard for this class of MBES.

The Sonic 2024 system can be upgraded to Ultra High Resolution – providing extremely narrow beam widths at 700kHz operation. The narrow beam widths at 700 kHz make this option invaluable for detail offshore site surveys such as pipeline inspections, cable laying operations, archeological wreck surveys or other micro bathymetry applications. When UHR™ is selected, the beam width is 0.3° x 0.6° (2024) , 0.6° x 0.6° (2022) and 1⁰ x 1⁰ (2020), providing unprecedented small bottom footprints.

Achieve soundings in excess of 450m below sonar using Continuous Wave techniques. The 2024 is perfect for projects that need the best resolution.

System Options

Ultra High Resolution

The Sonic 2024 and Sonic 2022 can now be upgraded to provide extremely narrow beam widths at 700 kHz operation. The narrow beam widths at 700 kHz make this option invaluable for detail offshore site surveys such as pipeline inspections, cable laying operations or other micro bathymetry applications.

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.

4000m Immersion Depth Rating

Sonic Wideband Multibeam Echosounders are available with 4000m immersion depth rated option for ROV/AUV applications. For 4000m rated systems, extensive pressure testing is performed to just over 400bar 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. If requested, the Sonic MBES can also be made available with 6000m immersion depth rating.

Switchable Forward Looking Sonar

The Switchable Forward Looking Sonar (FLS) Imaging Option is available as firmware upgrade to either Sonic 2024 or 2022 Wideband Echo Sounders.

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.
