Tura goes for another test flight.

North-east Sansara, from Swinside to Midge

The shoreline following sometimes works pleasingly well, but here it was a little vague, to say the least. Until I install some instrumentation, it's difficult to track down exactly what's going on. I suspect the ground gradient near the river was too flat and variable to give an accurate sense of what direction the river lay in. With the shore-finder producing noise, the navigation would be mainly driven by the contour-follower.
