The rowing computer built for race day — a 4.4″ sunlight-proof Memory In Pixel display, 10 Hz GPS, and live telemetry to your coach's launch.
Full sun, driving rain, dead batteries on the trailer, a coach 100 metres away — the RPX 440 was engineered for the days that decide seasons.
The industry-leading 4.4″ Memory In Pixel display gets clearer in direct sunlight — no washout, no glare, no squinting mid-piece. A custom-engineered backlight covers the dark end: pre-dawn water and late-night erg bays.
Race-ready 10 Hz GPS samples ten times a second — accurate splits on every single stroke, not the multi-stroke average a phone app gives you. Program custom workouts on-device and store 50 hours of sessions. No phone can match it.
Every RPX streams rate, splits, and stroke data to the coach boat over CrewNet wireless — real-time and low-latency, local to the water, with no smartphone and no subscription required. Coaches push workouts, program pieces remotely, and control devices without pulling alongside — 50 m and beyond, or 150 m+ with Long Range Repeaters. Need the whole lake? Pair a smartphone and you get unlimited range over cellular (subscription required).
Sealed against rain, spray, and the wash-down at the end of practice — the USB-C port included. And if the 440 ever goes over the side, it floats: no dive, no lost unit, no replacement to buy.
Every RPX is assembled and tested in our shop in St. Catharines — by the same people who designed it, on the same water it was built for. Warranty and support come from that building too, not a call centre.
