I wouldn' t worry right off on specific types of camo. Long as got some sort of camo on. Your setups themselves are just as important. You need to setup so your concealed well whether on the ground or up in a stand. Often just having a stand up in the air sticking out from a lone tree trunk with no branches doesn' t cut it, and you stick out like a sore thumb no matter what kind of camo you where. Its best to place your stand on the back side of the tree from expected travel, and if possible the sun at your back.
On bows, if you haven' t previously owned a bow or done much shooting start out simple. Invest into a simple beginner' s type bow to start. There are several good package bows on the market with about everything you need to get going. Most are even under $400. Its important to learn proper technique, and shooting. The faster they are often the harder they are to shoot. Your on the right track by going to a archery shop to start, and be properly fitted to a bow, do some shooting, and see how they feel to you. Don' t worry so much about having the latest, and greatest to start. There are alot of good bows out on the market. Its so competitive now companys have to put out good stuff or they die off quickly. Archers are keen to knowing junk when they see it! Also remember getting started is part of the adventure, enjoy it, and welcome to Bowhunting!!!!!!!
