COROS and have been working together to develop a tailor made workout mode that enable instant feedback on the water for all our major categories. The current release of this native speedsurfing mode is the first public version available for all COROS APEX PRO & VERTIX owners, and will bring a very high level of accuracy combined with a rock-solid hardware design, amazing battery life and a convenient easy-to-use user interface including auto-uploading to our platform (*).  In the next months we will continue to collect data and improve the speed algorithms together with COROS. Based on the progress we have made in the last months, supported by hundreds of test miles on the water, we are convinced this combination will lead to a future proof, trustable, accurate & verifiability solution that we want for our platform. 


Both the COROS APEX PRO en VERTIX are the first multi-sport watches suitable to support a native speedsurfing-mode , a large number of (extreme) outdoor/indoor activities and add additional functionality like HR and blood oxygen monitoring. COROS is a high performance sports technology company with a focus on outdoors and extreme sports. Combining high grade hardware and the latest innovative technology it’s providing athletes the gear they can rely on in the world’s most extreme environments. At GP3S we are extremely happy about this cooperation, the first time ever an industry leading manufacturer stepped into the world of speedsurfing and joined forces with our community !

In the next weeks we will share updates about our progress, we will give additional background information about the devices, software  and the way the GPS data is collected , processed & verified by our platform. As mentioned above we are actually in the middle of the development proces together with Coros, and based on the collected and verified data of the last months we are very confident it will reach our standards. The auto-sync feature will also be released before the end of Q4, this feature gives us additional posibilities to verify the RAW GPS data collected by the devices
