The Specifications on a Hoyt ProHawk Bow

Modern bowhunting uses new technologies to improve accuracy and reduce the amount of force needed to pull the string back and propel an arrow. Founded in 1931, Hoyt manufactures hunting and target archery products, including compound and recurve bows, arrows and other archery accessories. According to Hoyt, the ProHawk bow improves on previous models by incorporating lightweight construction and custom, modular draw lengths at an affordable price.


A compound bow, like the Hoyt ProHawk, features a modern design that uses a levering system of cables and pulleys to bend the limbs of the bow. The pulleys, also called cams, attach at the ends of the limbs and turn when drawing back and releasing the string to propel an arrow. For the ProHawk design, released in 2011, Hoyt narrowed the bow's parallel split limbs on the bow to lighten the overall weight of the bow and to provide more torsional and lateral stability over the traditional solid limb design.


Hoyt's Prohawk bow measures 32 inches from axle-to-axle. It has a ZRS 12 limb system and a 7.25-inch brace height. Available in custom, modular draw lengths, the Hoyt ProHawk bow also provides the option of the Hoyt M4 cam, which has a shorter draw length of 23.5 to 30 inches. The bow has a mass weight of 1.81kg. and a draw weight range of 9.07 to 27.2kg. It is available for either right-hand or left-hand use.


The ProHawk bow features Hoyt's Cam and 1/2 technology, a two-cam system tied together to prevent the pulleys from turning independently and to keep the cables in time with each other. Control cables and cables slides prevent the bow's cables from rubbing against each other. The system includes sealed stainless steel ball bearings, which according to Hoyt, reduce maintenance time by not requiring lubrication. The bow features Hoyt's TEC riser, designed to add strength and stability to the bow to reduce vibrations and increase shooting accuracy.

Arrow Speed

The ProHawk features an arrow speed of 305 feet per second, specified by the Archery Trade Association. Most bow manufacturers use the International Bowhunting Organization specification, which measures the speed of an arrow weighing 5 grains per pound of draw weight using a bow set at a 31.8kg. draw weight and a 30-inch draw length. Though very similar, the ATA specification requires more restrictive regulations for measuring arrow speed, creating some controversy in comparing the two standards of measurement.


Hoyt's ProHawk bow comes available in hunting colour options, including Realtree AP camouflage, Blackout, Max-1 camouflage and Half and Half, which is half Realtree AP and half Blackout. Hoyt also provides the option for custom paint and powder coat colours of red, blue, black, pink, pearl and white. (See References 2)
