If it will help you to spend more time in the field with your Father and he doesn't mind using one there would be no question at all.
Blinds have a place in turkey hunting just like decoys do,there are plenty of people that post here about how they would never use either,for whatever reason.
At the end of the day you decide what you are comfortable hunting with,after a few years of success you will make changes as your experience level grows.
If your just getting started its all about getting on birds and opportunities to kill them,if a blind and decoys help make that happen, great.
I have killed a handful of birds out of a blind and its not my first choice,but when I travel out of state there is always one packed in the truck,just in case of bad weather,and I have never had an issue using it when needed.
I have heard good things about these,might be worth a look.
