Nano G2 Ultra
When every gram matters but communication cannot be compromised. Built for the demands of British outdoor adventures.
Important: 868 MHz for Europe
Always buy the 868 MHz version for use in Europe. The 915 MHz version (US) is not allowed in Europe.
What is the nano G2 Ultra?
The Nano G2 Ultra answers a specific question: how small can a mesh device become while remaining genuinely useful? The answer sits comfortably in a jacket pocket while delivering 3.5-5 days of battery life.
The antenna design deserves particular attention. Most LoRa antennas perform poorly when pressed against the human body, but the Nano G2 Ultra maintains Signal integrity even stuffed in a rucksack pocket. This matters when you are scrambling across Snowdonia or navigating the Lake District fells.
B&Q Consulting (Unit Engineering) developed this device specifically for outdoor professionals and serious recreational users. Pre-loaded firmware means it works from the moment you switch it on.

Why the nano G2 Ultra?
Mountain rescue volunteers across Scotland and Wales have adopted the Nano G2 Ultra for its remarkable combination of portability and performance. Multi-day search operations demand equipment that outlasts the mission without becoming a burden.
The body-worn antenna optimisation proves crucial in practice. Standard LoRa devices can lose 10-15 dB when pressed against clothing and flesh, but the Nano G2 Ultra maintains consistent performance. The GPS module includes a physical switch allowing complete power isolation when position tracking is unnecessary.
Note: Battery must be purchased separately (3.7V 603450 LiPo). The device lacks WiFi, relying on LoRa and Bluetooth only. With an optional CardKB keyboard module, the unit operates completely independent of smartphones.
