Which impact meter should I choose?

When training in water sports, in addition to distance and speed, an important measure is stroke rate, for which several tools are available. 

Since 1978, Nielsen-Kellerman has been designing and manufacturing audio and measurement equipment for water sports and their combinations. Be it rowing, SUP, Ocean Canoe/Outrigger Canoe or kite boat. Their newest product group is weather and wind measuring devices. 

We offer several types of speedometers and speedometers, which differ in the amount of displayed values, their function, and their compatibility with other devices. 

Perhaps the most important difference between them is that the StrokeCoach only measures stroke rate using a three-axis gyroscope, not speed. SpeedCoach does everything Stroke Coach does and even measures speed using GPS. The Speedcoach GPS2 Training Pack does everything the first two do, and can be connected to multiple external devices via Bluetooth, has long-term memory and a programmable training function. 

In the following table, we have summarized the most important differences between the rowing stroke meter models.
