Micro Impeller. This can be used with HC or SX. Great for using during racing with low drag characteristics.
- The Coxmate micro impeller, now smaller, is the ultimate speed sensor.
- Spare impeller assembly (includes spare mounting tape)
- Provides less than 10% of the drag of NK impellers and its size makes it very resistant to picking up weed
- It can also be used with NK Speedcoach. Note: Speedcoach does not have any compensation for non linear characteristics
