S3+ Speed/Cadence Dual Mode Sensor

One Device, Four Uses.

The S3+ senor is the updated version of the GEMINI 200. By reinstalling the battery, you can switch the device between speed sensor and cadence sensor modes. Supporting connection via both ANT+™ and Bluetooth, S3+ is able to record data accurately, making it the best companion for a wide range of GPS computers and smartphone apps.

Smaller body, Longer Battery life.

8.4mm thick and only 8.8g. Nothing will impede you. With a CR2032 battery inside the battery life can reach up to 500 hours. Never stop ridding.

Accurate, Convenient

With a new geomagnetic sensor chip inside, S3+ has no need for external magnets but still provides accurate data. Optimize the battery cover and battery contacts for more convenient use. We refined the small details in order to give you a better user experience.

Dual Mode, dual protocol, more possibilities.

ANT+™ and Bluetooth dual protocol support makes it compatible with 90% of the training equipment on the market, and supports simultaneous connection of different protocols between two devices, allowing you to make multiple records of a single workout.
