Compact multi-use GPS with advanced navigation and removable battery
The perfect cross-over for two wheels or two feet, the OS Horizon is a compact, lightweight cycling and hiking GPS. Switch between flat or QuickLock back covers to adapt your device for the activity ahead, plus switch out the removable battery to stay out for longer. Follow your routes on a 3” touchscreen display that can be used in direct sunlight and in the pouring rain.
Using our world-renowned Ordnance Survey Explorer and Landranger mapping, 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. Thanks to our intuitive interface, the OS Horizon is really easy to use and will provide you with all the tools you’ll need to get going.
During your activities the OS Horizon will collect over 120 pieces of data so you can monitor yourself accurately, understand your performance and receive set alerts to avoid exceeding your limits. Link sensors using FullConnect™ (Ant+™, Bluetooth®, GPRS and Wi-Fi) to enhance your data, including heart rate monitors, cadence and speed sensors. To stay focused on the ride ahead, customise your data pages and homescreen to show the data that matters to you.
The OS Horizon has a QuickLock bike attachment built into the QuickLock back cover so you can quickly and easily attach the GPS to your handlebars. And so you can start riding straight away, it comes with a QuickLock Stem Bike Mount in the box too. Just twist, click and go!
Built to survive the Great British weather, the OS Horizon is protected by a rugged, shockproof, water-resistant (IP67) body, so you can get it as muddy and as wet as you like! You can also use the device and touchscreen wearing gloves, so you don’t have to take them off.
