Latest Generation High-Precision GPS & Algorithms
A modern 10 Hz GPS chipset with global satellite coverage ensures uncompromised accuracy. Combined with a high-precision accelerometer, gyroscope, magnetometer, and multicore CPU, the RPX Series rowing computer delivers a level of hardware–software integration far beyond general-purpose devices—maintaining precision from start to finish.
It takes more than advanced hardware to achieve high performance. We’ve designed and tested our algorithms across all levels of athletes and boat classes to deliver exceptional accuracy in stroke rate, splits, and more. You never stop improving—and neither do we—continuously refining our algorithms with fresh data to make every update faster, smarter, and more precise*.
*Firmware updates are available at no additional cost and delivered wirelessly to ensure that you always have access to the latest features and improvements.

Designed For Athlete & Coaches
Both the RPX 270 and RPX 440 give you the freedom to configure them as athlete or coach devices, offering unmatched flexibility as your program evolves.
In coach mode, real-time telemetry lets you monitor athlete performance from multiple boats live at a distance—stroke rate, splits, heart rate, distance, and more—while quickly and easily sending workouts, or changing the screen athletes are looking at to keep their focus where it matters.

High Performance MIP Display
Engineered for maximum sunlight performance, the RPX Series sets the standard for outdoor visibility with the most sunlight-readable displays in the world: a compact 2.7″ MIP panel in the RPX 270, or the largest commercially available 4.4″ MIP panel in the RPX 440. With a high refresh rate and a custom-engineered backlight found only in our devices, every stroke is seen in perfect clarity. Zero glare. Zero compromise.

Yes, it floats too.
Durable, waterproof, floating design. We've designed our product for rowing first. When you invest in a high performance product, you shouldn't need to worry about dropping it in the water. Every device undergoes a floating and waterproof test before shipping.

Range Extension
Extend your reach with the RPT Long Range Repeater. Boost range to 400 m+ and keep every athlete within signal distance. Mount it in the coach boat, the athlete shell, or both. With multiple coach boats, each RPT+ acts as part of a live mesh—expanding coverage and reliability across your entire program. This is your on-the-water relay.
