Overview

Micro-Ranger 2: Small in size – big in possibilities

Your entry level underwater tracking and positioning USBL system, based on world-class technology. It’s our most compact underwater tracking system ever, but don’t let its size fool you. Micro-Ranger 2 will improve your underwater tracking operations, bringing professional tracking over a range of applications. Micro-Ranger 2 can be used from any waterside location or vessel, including RHIBs and small survey or uncrewed vessels. It’s the optimal size to track divers, small ROVS and UUV’s or release moored equipment. It may be our smallest ever underwater tracking system, but Micro-Ranger 2 will have a big impact on your operations.

Maximum efficiency with the best value underwater tracking system on the market

It’s built on the same tried and tested cutting-edge hardware and digital acoustic technology found in the rest of our Ranger USBL family, so you can expect unrivalled performance without the complexity or cost. Its robust and compact format is ideal for your shallow coastal water and inland waterway operations thanks to its ultra-portable design. Track your divers and autonomous underwater vehicles at up to 995 m range.

Whether you’re a first-time user of USBL technology or a seasoned professional, you’ll find Micro-Ranger 2 incredibly easy to use – it’s a one box solution, make a few simple connections and your operation is ready to go!

We’ve engineered everything to fit in a robust carry case. Apart from your laptop to run the software, nothing else is needed and it’s so compact you can carry it on a plane. 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 take external power from a boat or shore supply.

Why choose it?

  • Portable, everything you need comes in one box
  • Quick to connect up and deploy
  • Easy to use, no training needed
  • Shares common platform with other Sonardyne USBLs
  • Light and compact, attach to divers and small vessels without restricting their operations
  • Developed and supported by a company with over 50 years of experience in innovative underwater technology

The kit

Transceivers

Ideal for tracking targets in shallow water up to the surface, the omni-directional acoustic tracking transceiver (MRT) is small and light enough to deploy on its cable from a pontoon, over the side of a vessel or on the sensor spar of a USV.

Micro-Ranger 2 software has many of the innovative features from our other larger Ranger 2 USBL systems to ensure you have everything you need to track underwater targets.

If your operations need to track and communicate with small AUVs or subsea drones, an optional Marine Robotics feature pack is available.

Transponders

What every diver, small towfish and micro ROV / AUV should be wearing, our Nano transponders are the perfect size and weight for tracking your important assets in shallow water without interfering with their movement. The two you will receive with Micro-Ranger 2 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 to suit your operation at the time of ordering. Micro-Ranger 2 can also be used with other Sonardyne 6G transponders including WSM 6+ and WMT.

Integrator/Marine robotics kit

If your operation needs you 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.
