Benefit of Nano for your applications
For energy
Nano is perfect for use on coastal and inshore survey and inspection operations which frequently require targets to be tracked at high elevation.
For defence
Its small size means it is ideal for tracking divers during training missions whilst the OEM version is perfect for use onboard specialist platforms.
For science
Nano is a low-cost way to keep track of your valuable scientific equipment inventory; AUVs, gliders, ROVs and instruments. Fit it and start tracking it.
Overview
Nano is our smallest ever USBL transponder, designed to let you know where your divers, man-portable AUVs, towed platforms, underwater drones and ROVs are throughout their mission.
Nano operates in the Medium Frequency (MF) band, so is compatible with our family of Ranger 2 USBL topside systems; Micro, Mini and Standard.
Measuring in around 160 mm In length, 55mm in diameter and weighing in at under 200 grams in water – depending on the exact version you’re using – Nano is small enough to fit on the smallest of vehicles and light enough for a diver to barely know they’re carrying one.
Nano’s built using the same signal technology platform you’ll find in our award-winning 6G product line – Wideband 2. So you can expect reliable acoustic communications in all operating environments, accurate position fixes and a continuous stream of location updates.
Nano features a 90-day quiescent battery life, ideal for long-term deployments and recovering lost assets. Nano’s battery lasts up to 12 hours, even when being actively tracked with one second position update rate.
The NFC Nano features a unique connector-less design that is recharged and programmed via the Nano Docking Station. The NFC technology allows full configuration of the Nano whilst maintaining its rugged “strap on and go” form factor.
The cabled Nano features an industry standard Subconn connector allowing the Nano to be permanently powered and can also be used in Responder mode.
When purchasing a Micro-Ranger 2 USBL system, we include two Nanos as standard. You’re available to choose between the NFC or connector version at no additional cost.
For vehicle programs and integrators, the Nano OEM when paired with an OEM transducer provides all the functionality of the housed transponders, in a form factor that can be mounted in any system.
Nano has an inbuilt depth sensor and is a 500 m depth rated unit.

Ocean Science
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.
