i like the grunt tube. just as long as they arent looking your way when you blow it. if they are coming in i wont blow it until they start to veer off course. i was hunting from the ground yesterday and saw a deer through the woods in the cut corn about 90 yards away. i didnt like where i set up so i ran about 5 steps while blowing the grunt tube to get behind this clump of trees and within 2 minutes i had that doe from the field at 10 yards. i ll use a call to cover up some steps if its crunchy leaves and i feel that the grunting and sounds of leaves crunching convinced that deer there was another close by and it came over to investigate.
