You can get a lot of different types of traditional bows, and not break the bank. Don't get to much draw weight, test shoot some bows to see just what you can handle then decide on how much weight to buy. 50 pounds is a lot for a young lad, but if you have a short draw length it may be ok, and you will grow into the full weight as you get bigger.
For around the $200 mark you can find Longbows and recurves in 1 and 3 piece.
You will need arrows to match the bow, a glove or tab, and some way to carry the arrows, a bow quiver or side quiver work best for hunting.
Take a look at my reviews for the Samick Sage, Bodnik / Bearpaw Hard Hunter, Bodnik / Bearpaw Sioux, Tombow, and Crow. These are all reasonably priced and shoot good.
With traditional you don't need a rangefinder. This is close up hunting.
my reviews are here

The Sioux, and Tombow are normally in youth weights but they are available in draw weights up to 55#. What area do you live in so I can steer you to a traditional bow shop.
