Archery has always been a source of curiosity. It has fascinated people through
the ages and people are still very much excited about it. It's well known that
bow and arrows are amongst the earliest forms of weapons. They are the "guns" of
that era. What's most interesting is that people throughout the world discover
them as a means of hunting or war. This proves that they are indeed useful for
these two purposes and have served men well. Since firearms have replaced the
role of bows and arrows in war, archery is now conformed to only sports and in
some countries, hunting. Followers of the Olympic Games will also remember that
archery is also an event and other archery events and tournaments are also held
all across the World.

Compound Bows TodayCompound bows are modern improved variants of bows. They are characterized by much stiffer limps, a significantly different design, and use of pulleys or cams as a levering system. As compared to recurve bows and traditional longbows, they have greater accuracy, range, durability and velocity of arrow. They are also lighter and easier to use and sometimes have aids such as sights and triggers.Compound bows were first developed in 1966 in the United States. The design of a compound bow is significantly different from that of the traditional types of bows. The central riser which is a mount for all other components of the bow is made to be very rigid, often of aluminum or magnesium alloy. Many are made from 6061 aluminum alloy, which is an aircraft-grade alloy. Limbs are made from composites-modern materials developed to be light and withstand high tensile and compressive forces. All the potential energy for shooting the arrow is stored in the limbs. There is a cam or wheel at the end of each limb, which transfer the energy from the archer's hands to the limbs of the bow during draw and from the limb to the arrow during release. There are different ways of engineering the cams for storing energy in the limbs, which are categorized under 'bow eccentrics'. Four most common configurations are single cam, hybrid cam, dual cam and binary cam. Other though less common designs include hinged and quad cam. The strings and cables are made from high-modulus polythene, designed for bearing very high tensile strength and minimal stretchability. This is done to transfer energy to the arrow with optimized efficiency and durability. The arrows shot by compound bows are similar to those used with recurve bows, but stronger. They are usually made of aluminum or carbon or both.The string which is drawn by the archer is attached to the cams, the lower or both of which have one or several cables attached to the opposite limb. This arrangement allows the limbs to store more energy, and thus they are stiffer. The draw-force curve of the compound bow is excellent for archers to hold a fully-drawn bow while aiming. The force required to hold the string drawn rises to a peak force and then lets off to a lower value, making it easier to hold. This is achieved by mounting the axle joining cam to limb at the edge of the cam instead of the center. Compound bows usually come with rubber blocks to act as draw stops. These help to set a draw-length, which keeps force imparted constant and gives an anchor point improving accuracy, especially for targets at the same range. Thus a compound bow gives better statistics while not being too difficult to draw.Compound bows have many advantages over traditional bows. The major advantage is improved usage statistics. They are also resistant to temperature and humidity changes. Stabilizers and dampers are well-developed for composite bows. Also triggers and sights can be mounted. These bows dominate the hunting scene nowadays and are manufactured by professional companies.Archery Equipment - Choosing the Keys to SuccessThere are several reasons why you may want to take up archery. Maybe you took archery in gym class and enjoyed it. Maybe you want to join the archery team. Perhaps the tale of Robin Hood sparked interest in the sport. Maybe you would like to go hunting but don't want to use a gun. No matter what your ambitions are, you are going to need archery equipment to practice with. One important piece of archery equipment you will need is a bow. When choosing a bow, it is important to buy one that matches your skill and comfort level.This is why it is very important to try as many different types of bows as possible. There are several different types, but the most popular ones are the longbow, recurve bow, compound bow, composite bow, and cross bow. Long bows are longer than normal. The added length allows the arrow to travel further. It is also light weight and stable. The recurve bow allows for more spring force when drawn and is commonly used by Olympic and sporting archers. The compound bow uses a levering system composed of cables and pulleys. The bow is energy efficient and insensitive to temperature changes allowing for greater accuracy, velocity, and distance. The cross bow sits sideways on a frame and the limbs can be pulled back mechanically. Because it has a rifle like body, the shooter can carefully aim short arrows.Once you choose the right bow, the next important piece of archery equipment you will need is arrows. Wooden arrows are the cheapest kind and mostly used for beginners and men longbow competitions. They tend to warp and break easily. If you plan to be doing a lot of hunting, you may want to purchase fiberglass arrows. Fiberglass arrows can be fitted to draw weight and length and are consistent and reliable. These also tend to break easily. If you are going to be hunting big game or entering tournaments, use aluminum arrows. Although they are expensive, aluminum arrows are durable and come in a wide range of sizes. The most expensive type of arrow is carbon composite. These arrows are used by serious hunters and archers who want speed durability and efficiency.After you find the right type of bow and arrow, you can purchase other archery equipment. You can purchase a case for your arrow and bow, arm guards, or a silencer. There are also additional accessories you can buy to fit your needs. Good luck and have fun practicing archery.
