In addition to getting the right bow, you'll need several other items before heading out to the archery range. Choose an arm guard to protect your inner forearm from the snapping string. Excellent leather guards with elastic straps are available at many sporting goods or hunting stores - or you can use a small piece of cardboard with some heavy rubber bands to save money. Decide on a method of finger protection. Not only does finger protection guard your fingers from the string, but it also allows the string to slide smoothly off your fingers.
Gloves are easier to use than the tab, but the tab is definitely cheaper.
Buy only a few arrows at first, ideally purchasing several different types of single arrows from the racks. Beginning archers lose and break many arrows, so this will give you a chance to figure out what you like best. Once your shots consistently land on the target, go ahead and buy a full set of whichever arrow type works best for you and your shooting purposes. Choose a quiver. This is not an essential device, but it sure makes life easier.
