Ive had deer under my tree already,and played with them to see there reaction.They all look arround for 3-5 seconds,then they loose intrest and continue feeding.It didnt scare them away. Early in bow seas. i tried the bow-grunt set real soft and it scared the hell out of the does! So did the doe decoy,Man they saw that thing and ran like hell!Ill keep at it,Come to think of it,I did shoot a doe this year with a bow grunt.She had already shot across the trail in front of me as i was walking back twards my truck.I figured what the hell it couldnt hurt,and gave it a snort.She stopped,and came back to the trail,I snorted again and she stepped out.30 yd.dbl lung with a climber on my back.I love my bowtech
