Ideal speed for sonar to work? - Kayak Fishing Adventures on Big Water’s Edge

The speed recommendation is probably based on when you are using the SI and DI for mapping. It is slow enough not to miss anything, but fast enough to dilute the errors from cross wind and current. Your transducer will always assume that you are traveling straight in the direction your GPS shows. If you have some drift from wind or current, the SI and DI will have some error. If you were paddling backwards, the SI and DI would show exactly opposite (right is left and left is right).
