The camera tube moves with the current, 360 degrees around the float. The camera tube drift is adjustable according to the magnification. A setting for 4-6mm feed and a setting for 6mm-12mm feed.
The camera tube will provide an almost perfect camera hit point in all current conditions. The camera tube will lie flat in the water surface if the current is too strong to conduct. This way you will not have to test feed and waste with feed to try to find the feed with camera.
The system has been used since 2002, and experience shows that one manages to maintain a lower feed factor and higher growth than the average in Norway.
