RE: Help a Beginner..
As far as equipment wise, the other guys have hit it on the head. Go to a pro shop, find a decent bow and setup that you can afford, and start researching anything about bowhunting. Thing is, you probably wont be able to deer hunt with it this season. Bowhunting take a lot more patience and precision than rifle, so the most respectful thing to the animal you can do, is to get to know your equipment inside and out before trying to hunt with it. Research as much about deer that you can in order to get to know the animal better. Knowing how they think can be the difference in seeing or not seeing deer, and having them come within the "magic" range of 20 yards.
Advice about equipment. Parker makes some great starter bows, as well as diamond, martin, PSE, and even hoyt. You may want to try to save though and invest in a higher dollar bow. Higher price doesnt necessarily mean higher quality though. Shoot as many as you can to get a feel. Specs on bows to look for should have a brace height around or over 7 inches, an axle to axle above 34 inches, and you will want to look at cam style. Solo cams i think are a lot easier to work on and tune, but they are harder shooting than some of the two cams or new hybrid cam systems. I dont know the area you hunt, but a heavier bow is more stable and has less shock. But sometimes the extra weight is bad if you have a lot of area to cover. As far as arrows, a dozen carbons will last longer to begin with because they dont "bend" like aluminums and when starting that is a good way to cut price so you wont have to buy straight arrows all the time if your missing while getting use to the bow. Get a good release! Out of all things you'll get to start, dont be cheap on the release. Tru-ball tornados are a great one because of the "surprise" built into them, and they run around $50. Archers choice makes the Grizzly sight which runs around $25. For rests, id say either go star hunter(i still love those rests for some reason), or (dare is say) the whisker bisquit. Go to a pro shop, and not bass pro or any other high retail. Half those people are just selling you something and dont know that much about it. Go to a pro shop and ask as many questions as you can, thats what they are their for.
