The Tocsen crash sensor integrates with the rider's smartphone via Bluetooth and automatically triggers an emergency call including location details in the event of a fall. This unique technology, consisting of a Tocsen crash sensor and smartphone app (Android and iOS), automatically detects a fall. If the rider does not respond within 30 seconds, the system automatically notifies the emergency contacts in the app and guides rescuers directly to the place where the accident has occurred. An additional setting in the app provides the option to trigger an automatic emergency call to all Tocsen users in the immediate vicinity. As a result, every Tocsen users becomes a potential first-aider. Fits the Yelm Hybrid helmet.
