Diamond Archery. Diamond compound bows are made by the BowTech Archery Company. The bows that are made under the Diamond label are the single cam line of bows providing a great deal of adjustability in the draw length as well as smooth timing and a nice fluid draw across all of the bows. They do this by means of the solocam that powers each bow.
Some fine synthetic bows are also made of fiberglass and other man made materials. Cheaper bows can also be made of synthetic materials and less suitable types of wood.
