Garmin Speed Sensor 2

Garmin’s second generation speed sensor is a true all-rounder. In addition to the basic feature – which is giving you accurate speed – it offers dual connectivity (ANT+ and Bluetooth LE) and an internal memory that tracks up to 300 hours of activity no matter which compatible GPS device you are using.
This allows you to collect trip time and distance data without connecting the sensor to a training computer.
Moreover, the Speed Sensor 2 directly connects to the Garmin Connect™ app on your smartphone using Bluetooth Low Energy. Apart from transmitting all activity data (distance, time) from the internal memory of the speed sensor, the app provides further information, such as connectivity details (paired with ANT+ or Bluetooth LE protocol), battery charge, software version (updates available in Connect™ app) or wheel circumference (choose the type of calibration: Enter your wheel size manually or let the sensor detect your wheel size automatically while riding).
