Whether or not you want to upgrade your equipment you can spend minimal dollars to go to a pro shop and have them fit the bow to you a little more. By that I mean getting them to set the bow to your draw length. Get your arrows cut to your size. Then put on a peep sight, kisser button (I recommend the kisser but some don't use one), a new sight, and rest.

What you need to do to start hitting more consistently is to get more consistent about how you draw, hold, aim, and release the arrow.

Get to a pro shop and tell them you'd like help setting this bow up to you. I recommend at least the items I mentioned above with a nock for the arrow on your string and a string loop to use with a release aid of some sort.

All the terms and what you need is overwhelming at first. (It was to me) Unless you have a buddy that bowhunts I recommend getting to the pro shop for help.

I am fairly new to this to and that is all I can think of. Good luck.
