Interesting concept from SG20 for a smart device that attaches to your snowboard and uses sensors to detect your board’s angle, movement and adjustments 15 times per second. Supposedly it can even detect terrain features like an ice patch and then capture the coordinates and alert others via the SG20 bracelet or on their smart watch (think WAZE for the mountain).If a rider find themselves in an unsafe area they will receive notifications. Also alerts will be sent in the case of a a traffic jam or other obstacle ahead beyond view. Unfortunately SG20’s website is down at the moment but if you’re interested I suggest you follow their Youtube page HERE:
