SpeedCoach GPS 2 is

Impeller Compatible

The SpeedCoach GPS is compatible with our SpeedCoach Impeller (sold separately). Training with an impeller has been the gold standard for rowing for years, especially for teams that train on moving water. Impeller speed measures the movement of the boat relative to the water, while GPS speed measures the movement of the boat relative to the ground. This can be a powerful training tool and a great way to learn more about your paddling. To get started training with an impeller you will need the SpeedCoach Impeller Wiring, Wireless Angle Bracket Mount, and SpeedCoach Impeller.

If you are interested, we wrote a blog post highlighting the differences of impeller speed versus GPS speed.
