Overview
MRT is one of the smallest USBL transceivers on the market providing you with complete flexibility with where you use, how you deploy it and what you track with it.
It’s supplied as part of our Micro-Ranger 2 USBL system, a complete one-box underwater diver, ROV, AUV and equipment tracking solution. Everything you need, including two transponders, is supplied in a battery-powered IP-67 rated carry case for portable, go-anywhere marine operations.
MRT is supplied with a moulded 10 m underwater cable that is connected up to your Micro-Ranger 2 command case. The cable provides both power and comms to the MRT
Deployment is as simple as it gets. Off a pontoon, over the side of your RHIB or even fixed to a USV. It can be suspended using its cable or on a simple pole arrangement. We even offer a lightweight carbon fibre pole with fixation clamp and a top bracket to mount the system’s included GNSS antenna.
MRT uses an integral AHRS sensor which provides pitch, roll and heading data that automatically compensates for the dynamic motion of the vessel, removing the need for an external sensor and pre-use calibration. It’s multi-element processing enables transponders to be accurately positioned at ranges of 995 metres.

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.
