Welcome! First, you don't need a 70# bow to hunt whitetail but it helps with extra speed and ke. There are lots of bows at most shops that are a year or two old and would be great starter bows. You might pay a few bucks more but you will get fitted corectly ata local shop. The most importaint thing is get you draw and so on right. It takes alot of time to get ready for the first bow season and you owe it to the game to be as proficiant as possible.
