Much can be said regarding the instinctive style of shooting used by traditional bowhunters being the best shooting style for hunting, but the use of some key accessories on modern bows can go a long way to making your shots more accurate, especially if you are just getting into using a bow for hunting.
Arrow rests: The arrow rest is what the arrow rests on as you are shooting. It can be as simple as some hook-and-loop strips on the riser or a stick-on rest with a movable arm. More-sophisticated rests are fully adjustable and drop out of the way when you shoot.
Sights: Sights are used if you do not want to, or cannot, shoot instinctively. Like an arrow rest, they screw onto the riser and have adjustments for windage and elevation.
Quivers: Quivers can be attached to the bow with screwedon brackets; alternatively, they can be strapped on at the top of the riser. They hold anywhere from three to seven (or more) arrows and come in a variety of designs.
Stabilizers: Stabilizers screw into the front of the riser and help balance the bow in your hand. They also absorb any energy left in the bow so that it doesn’t turn into noise or hand shock.
Arrows: The right arrow is vital to your shooting success. You must pick arrows that are stiff enough at your draw length to fly well off your bow. They should have enough mass to absorb as much of the energy possible from your bow and keep it while they fly to the target. The energy the arrow retains until it gets to the target defines how much momentum it has for penetration; the heavier it is, the more energy it will absorb and retain during its flight and transfer to the target upon impact.
