Rowing's most popular performance monitor, the SpeedCoach GPS 1, offers athletes critical information about boat speed (split), stroke rate, distance, and time. Use by itself in GPS mode or connect to an impeller (impeller and wiring sold separately) for additional accuracy in moving water. The Training Pack features now come standard. Program any workout ahead of time, start and record pieces without letting go of the oar handle and upload the data wirelessly to a computer or mobile device. The SpeedCoach GPS with Training Pack supports the EmPower Oarlock and is the central component of NK’s connected rowing environment.
