I have the Extinguisher grunt/doe bleet grunt call.
& let me tell you, it works for me.
I've had deer from at least 100 to 120 yards away change their direction & come running at me when I grunted on that tube.
I've even vocalized with young does,
I don't know what was being said, but it was pretty cool.
I have used it for both seasons with success, so if your buddy refuses any of the aids you mentioned to him, he must be a pure old school hunter & doesn't want to change. I know people like that too.
yes he is for sure! The exact answer was, " I have been doing this for 20 years and always fill my tags with out any of that stuff"
I always like to hear opinions of a group or more so I am able to make a better choice, Not trying to be a "ask hole" (ask for advice then do the opposite) but to better choose what a good solution is with out being sent in the wrong direction or with poor advice.
