Eastern Iowa | I just did some spraying and the Rogator speed read accurate within .1 mph, I think it is radar, The Raven Viper Pro is GPS and it fluctuated .5mph. I don't remember how much the magnet sensors fluctuated. I would check to make sure everything is tight and clearance is correct. On my old sprayer the speed sensor for the flow meeter is the same as the one used on the speed sensor by the wheel. You could swap them out to check it if you have one. |
