Benefits of of Micro-Ranger 2 for your operations
Portable and quick to mobilise, it can be deployed from any waterside location (pontoon) or vessel-of-opportunity, including small survey vessels.
Micro-Ranger can be operated from a small RIBs and even configured for installation on a uncrewed surface vessel for remote missions.
Its small and portable size makes it ideal for supporting science operations conducted in rivers, lakes and coastal waters.
Portable and quick to mobilise, Micro-Ranger 2 USBL can be used from any waterside location or vessel, including RHIBs and small survey vessels, to track divers, underwater vehicles and equipment.
It may be our smallest ever underwater tracking system, but Micro-Ranger 2 will have a big impact upon your search and rescue, inspection and survey operations.
It’s built around the same market-leading 6G hardware and Wideband 2 digital acoustic technology you’ll find in our family of deep water USBL systems, Mini-Ranger 2 and Ranger 2, but for significantly less cost and complexity.
We’ve engineered everything to fit in one medium-sized IP67-rated ruggedised carry case; power supply, command unit, GNSS antenna, transceiver, 10 metres of cable, two Nano transponders, charger and ancillary cables. Apart from your laptop to run the software, nothing else is needed and the size is so small, you can carry it on a plane with you.
If you’re a first time user of USBL technology, you’ll find Micro-Ranger 2 incredibly easy to use. Simply connect your computer, external GNSS and transceiver to the system’s common interface unit, then attach one of the included transponders to a target you want to track the position of. With the transceiver lowered into the water and your laptop linked via WiFi to the carry case, you’re ready to start tracking at up to ranges of 995 m.
A built-in battery provides more than 10 hours of continuous use, enough for a full day of activity out on the water. The case can also accept external power from a boat or shore supply.
The Micro-Ranger Transceiver (MRT) is extremely small and light and can be deployed from the side of a vessel, pontoon using its cable, or on the sensor spar of a USV. Its design provides omni-directional acoustic tracking coverage, so is ideal for tracking targets in shallow water to the surface.
Micro-Ranger 2 software comes with a lot of advanced and powerful features selected from our Mini-Ranger 2 and Ranger 2 USBL systems to ensure you have everything you need to track underwater targets. If you need to track and also communicate with small AUVs and drones, an optional Marine Robotics feature pack is available.
Nano transponders are the perfect size and weight for divers, small towfish and micro ROVs. The two that come in the case are second generation units offering extended battery life and depth rating. A connector-equipped Nano is also available allowing it to operate continuously via an external power source. Simply choose the type of Nano transponder that comes with your system at the time of ordering.
The system can also be used with other Sonardyne 6G transponders including WSM 6+ and WMT.
If you’re an AUV developer who needs to both track and communicate with targets, the Micro-Ranger 2 integrator system kit is available. It comes complete with our add-on Marine Robotics software pack and AvTrak 6 Nano, which support two-way messaging, vehicle control and tracking in one small instrument.

Micro-Ranger 2 USBL case studies
Micro. For when good is good enough
Micro-Ranger 2 is our smallest ever Ultra-Short BaseLine (USBL) system, designed for first-time users to unpack, install and start tracking. It’s providing an easy to deploy yet important tool for monitoring coastal habitats in Australia, as Fathom Pacific’s Director and Principal Consultant Dr Adrian Flynn sets out for us.

Deploy, retrieve, repeat – made easy with RT 6 acoustic release
Shallow water isn’t any less demanding than deep water. DynamOcean operates in tidal estuaries with fast-flowing water and ever-changing environmental settings. Using our acoustic releases and underwater positioning technology they were able to reliably deploy and retrieve their ADCP sensors.
