Bluetooth Impeller Sensor and Impeller for ActiveSpeed

This includes everything you need to use an Impeller with your ActiveSpeed. However, if you want to use it in an Eight, with the Impeller located the recommended 5 metres from the bows, then you will need the extended version.

The impeller design was optimised using Computational Fluid Dynamics software and its drag matches the alternatives that are available. However, all impellers create significant drag so we recommend that it is only used for training and is removed for racing.

Every effort has been made to make it as practical as possible: it can easily be fitted and removed using 3M Command Adhesive Strips, the spinner is supported at both ends to ensure it is robust, it has a clip on ‘keeper’ to prevent wear while in transit, and it comes with the Impeller Alignment Tool, that makes it easy to fit.
