not sure about accuracy but I know mine can be calibrated to be pretty close to GPS SOG when steaming in calm conditions. On my boat however because the paddle wheel is mounted slightly to port of center line towards the after end of the keel if I calibrate it to read the same as the gps sog on port tack then it will not be calibrated to read the same as the gps sog on starboard tack...I attribute that to water flow around the keel near the paddle wheel related to the paddle wheel being in one case on the windward side of the keel and in the other case on the leeward side of the keel...I simply try to split the difference but I favour higher "feel good" numbers for everyone in the boat to see
