Nano – Small ROV, Drone, AUV & Diver Tracking

160mm long by 52mm in diameter; USBL transponders don’t get much smaller than this.
It may be small, but it’s big on performance; just like the Ranger 2 USBLs it works with.
Fits in seconds to your divers and vehicles – then you’re all set to track them.
Once you’re done for the day, recharge it using wireless charging. Simple.

Think our transponders are too big to fit your vehicle? You might need to think again.

Meet Nano, our smallest ever 6G-enabled positioning transponder. Use it with our Micro and Mini-Ranger 2 USBLs for keeping track of your divers, small AUVs and micro ROVs. Choice of depth ratings. Connector-less design. NFC charging. Features that are anything but small.

Nano is our smallest ever USBL transponder designed to let you know where your divers, man-portable AUVs, 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, 52 mm in diameter and weighing in at just over 200 grams - depending on the exact version you’re using - Nano’s 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 Wideband 2 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 connector-less design meaning there is no need to worry about damaging an underwater connector. Its recharged and programmed via the Nano Docking Station which takes around 12 hours to fully recharge the high capacity battery. This gives up to 15 hours of in-water use with a position update rate of once every five seconds.
Two versions of Nano are available; a 300 metre, depth sensor equipped version and a 500 metre depth rated unit.
