HR sensor inconsistent between run and SUP

HR sensor when running is far more accurate, but when i do rowing (SUP) heart rate is far below acurate. Anyone have same problem? and what is the solution?

I haven't tried SUP, but I experienced the same when backcountry skiing. Apparently, doing rhytmic movements with your hand may confuse the sensor. My solution was to start wearing an HRM chest strap.
