If you got your 101 I-pilot all set up, you shouldn't need a drift sock. Point the nose of the boat into the wind, use the auto pilot on the I-pilot and just adjust your speed you want to drift. Works real well. Note: on the hand held ( I mainly use the foot pedal buttons as for me it's easier than the remote) You push and hold the N button till the circle around the N goes away. The circle is the advanced mode, you just want the auto pilot mode. Or you can use the button on the foot pedal.
