By combining latest technology with an updated software and a proven design, the Teasi One 4 GPS device follows in the footsteps of its successful predecessor Teasi One³. And in combination with the comfortable Bluetooth 4.0 heart rate chest strap, you’ll have everything you need for heart rate based training.

Everything that has proven its worth remains, while all niggles are eliminated. Besides, the 4 Series model offers enhanced processor performance and additional memory without compromising on battery life. Thus, you can constantly use the device for up to 12 hours, even though RAM has been doubled to 256 MB and a powerful 800 MHz Mstar integrated into the housing for more performance. This primarily results in reliable and fast rerouting when leaving the course. The display, too, has been optimized to make it sunlight-readable. This eliminates the need for energy-consuming contrast enhancement.

The Teasi One 4 is a true all-rounder – packed with everything hobby athletes and outdoor fans might need. It is compatible with all accessories for the Teasi One 3 and Teasi Classic. The attractively priced GPS device comfortably shows you the way. You can choose between different profiles for cycling, hiking, skiing and boating. The device provides easy and reliable route navigation in all countries of Europe and features a precise 3D compass. Some maps are already preinstalled. The built-in trip computer with GPS and compass provides information on the course, distance, speed, gradient, altitude and calories. The fitness feature allows you to plan routes based on time, distance and calories, save and re-experience them with the tracking feature. Therefore, you can also track your heart rate, cadence and speed with optional sensors via Bluetooth. The TAHUNA tool allows you to save your tours, organise them or sync them with data from the portals bikemap.net and wandermap.net. Besides, you’ll get free software updates and map updates via TAHUNA online.
