The StrokeCoach you love, updated with 21st Century technology! The StrokeCoach with Surge Rate provides every StrokeCoach function – stroke rate, stroke count and elapsed time – with absolutely NO wiring or seat magnet required! NK’s proprietary stroke algorithm, combined with a sensitive three-axis accelerometer, gives immediate accurate stroke rating in any boat – rowing shell, dragon boat, canoe or kayak – and in any position. The StrokeCoach Surge comes with a convenient "strap-on" mounting dock that makes short work of attaching it to your boat. Have a team boat? No problem! The StrokeCoach with Surge Rate will give you an accurate stroke rate in ANY seat in the boat! And, in response to your requests, we've added a backlight so no more flashlights during those early morning rows. Our test team of rowers and paddlers have told us loud and clear - this might be the most useful addition to the NK® line ever!
