Good tool to have. Throw it out the front and backtroll into the wind. Ultra slow and boat control is a snap. Drifting with one by the trolling motor is asking for trouble, so if we go that way the sock is out the back of the boat with the motor on the front. Straight drift the sock is in the middle. On real windy days, I'll use 2 or 3 to slow down enough. Trolling motor batteries last much longer when you don't have to have them going all the time. Look for ones with weights and floats. They work immediately, while the ones without might take awhile to fill up and will also tangle more than the ones with weights. If you get a few, look for rubberized canvas and ALWAYS dry it out when you are done. Otherwise you will have a moldy, stank nasty mess. Have Fun!!!
