OS GPS following a route with waypoints

Routing, waypoints and alerts

Discover new places and explore old favourites. Follow routes with loaded waypoints and receive alerts for directions and points of interest. You can also record your own routes, adding waypoints along the way.

Upload routes from GPX files, OS Maps and more.


OS GPS battery life

Exceptional battery life

Go further than you ever have before. With over 20 hours of battery life, enhance your activities by staying out for longer without having to turn back sooner.

The OS Aventura also includes a 24-hour interchangeable battery to cover even more ground.


OS GPS waterproofing demonstrated

Rugged body and water resistant

Built to last and survive the Great British weather, the OS GPS range is protected by a rugged, shockproof, water-resistant (IP67) body, so you can tackle all extremes.

Whether it’s rainy, snowy, windy or muddy, your OS GPS will have you covered.


OS GPS SeeMe Tracking functions

SeeMe™: Peace of mind

In case of emergency, send your exact coordinates via SMS and email to two emergency contacts from anywhere in the world – all without a mobile.

You can also broadcast your activities in real-time to friends and family straight from your GPS, so they can track you every step of the way.


OS GPS connectivity and sharing

Connect and share your activities

Share your routes and stats on Strava, GO (by TwoNav) and social media. Look back at your activities and analyse distance, altitude, speed, time and more.

Plus, connect with OS Maps to share routes between your GPS and view your activities in 3D on your computer.
