BioSonics Launches First Fully Autonomous Scientific Split Beam
On the leading edge of scientific sonar technology since 1978, Seattle-based BioSonics today unveiled their latest innovation in underwater monitoring, the DTZ Explore. This compact, low-power, split beam sonar system is the first of its kind and opens up new exciting possibilities in underwater monitoring to support ocean intelligence and environmentally responsible development of offshore energy, aquaculture, research and more.
DTZ Explore brings the power of a traditional vessel-mounted sonar system into a compact, energy-efficient package. The small but mighty DTZ Explore gives access to a full water column while producing quantitative datasets to assess biodiversity and marine life with always-on data collection and real-time reporting. The efficient device provides the most scientifically defensible data possible on a wide range of organisms from plankton to whales.
The 6-watt device features BioSonics’ split beam sonar technology, cutting-edge System-on-Chip (SoC) architecture, and an integrated Linux-operating system, all inside a fully submersible device the size of a volleyball. It autonomously collects and stores high-resolution marine life data, processing it in real-time with onboard Edge computing, and transmits critical insights via Ethernet or RS-232, with cloud connectivity.
“Split beam sonar methods are considered the gold standard for providing precise, defensible scientific data for monitoring aquatic life and behavior” said BioSonics CEO Tim Acker. “Data that is needed for project permitting and stakeholder acceptance. Traditional split beam sonar sensors typically required deployment from crewed vessels. The DTZ Explore can easily attach to any uncrewed mobile or fixed platform of choice.”
Whether monitoring fish schools and marine mammals around offshore energy sites or tracking aquaculture behavior and health, DTZ Explore simplifies operations with its plug-and-play design and versatile deployment as an external sensor on mobile or fixed uncrewed platforms, such as UUVs, USVs, data buoys, seabed landers, ADCPs, and ocean observatories.
“The DTZ Explore is the culmination of a multi-year development plan to invent the world’s most advanced, compact, and easy to use split beam sonar system,” said Acker. “We’re proud of our dedicated team of scientists and engineers who believed in our vision and poured their passion and incredible talent into making the DTZ a reality. With the right strategic partners, we look forward to getting this in the hands of marine tech, offshore energy, and aquaculture companies worldwide.”
Teledyne Marine Launches Intrepid – A GNSS/Inertial Navigation System

Expanded vision: Introducing Voyis' discovery stereo camera for shallow depths
Last year, Voyis revolutionised underwater operations with the launch of the Discovery Stereo camera, boasting an impressive 4000-meter depth rating with high accuracy dome viewports. This innovative product delivered true depth perception and real-time 3D modeling to ROV (Remotely Operated Vehicle) platforms across the ocean sector. Taking an innovative approach, the Discovery is a more than a stereo camera, it is a Vision System that simultaneously records low-latency piloting video, high-resolution stills images, and 3D models. With a wide 75°x75° field of view and onboard edge computing, the system instantaneously delivers 3D depth maps to enable true autonomy, from fine manipulator automation, accurate vehicle docking and visual tracking, or station keeping without seabed bottom-lock.
Today, Voyis releases a 300-meter depth rated version of the Discovery Stereo, delivering the same performance and accuracy but in a package that is lower cost and neutrally buoyant.
Key Benefits of the Discovery Stereo 300m Rated
A remarkable feature of the 300m rated Discovery Stereo camera is its neutrally buoyant design that is achieved without compromising on the proven system accuracy. This advancement drastically simplifies integration into small ROVs for shallow water applications, ensuring ROV piloting dynamics are not affected.
The most intricate details of the underwater world can now be captured on smaller platforms that are both lower cost and easier to deploy. With the neutrally buoyant Discovery Stereo camera, you will experience enhanced stability and ease, allowing you to capture stunning images, video, and 3D data with simple integration.
The paired Nova Mini lights are smaller and employ corrected optics that expand the illumination coverage. This ensures the entire camera’s field of view is perfectly illuminated, maximising target coverage rates, and improving the robustness of tracking algorithms.
In addition to that, the 300-meter rated Discovery Stereo camera generates the highest quality datasets in this depth class. With other shallow rated stereo products compromising on performance to achieve their reduced cost and weight requirements, 300m Discovery maintains all product functionality and accuracy, simply in an optimised form factor. This new product version was created to assist operations in shallower water, without compromising data quality and precision.
By prioritising both performance and adaptability, the Discovery Stereo camera empowers users to navigate shallower waters without compromising on the unparalleled quality of the collected data. Its advanced features not only elevate the standards for underwater inspections but also make it an indispensable tool for various ocean sciences and civil infrastructure applications where precision and data integrity are paramount.
