Highly recommended!
I applaud Nielsen & Kellerman for offering the SpeedCoach app for the iPhone. Combined with the water tight pouch this app works better than the old conventional SpeedCoaches before. It is great that I can use my iPhone with the SpeedCoach in any boat. No need for wiring or the impeller. It is clearly visible in the dark. It makes more data available than previous instruments, such as the check and the bounce factors. One draw back: I wish it were possible to temporarily disable the phone or text messaging while rowing with the SpeedCoach. Its kind of distracting to get a message or phone call in the middle of the workout. Maybe its actually possible to do that except that I havent figured it out yet.
