For increased visibility and arrow tracking, Bloodsport Hunter Strobe crossbow arrows now come with an innovative strobing lighted nock. These rugged polycarbonate half-moon nocks feature multicolored strobing lights that are far more effective than static lights for helping to see the shot and retrieve arrows in low-light conditions. Their pressure-sensitive design ensures they switch on automatically at the shot and remain on up to three days. Once found, they can be easily turned off with an on/off toggle switch. Paired with proven Bloodsport Hunter carbon shafts, these arrows come fully assembled in a three-pack. Tested for durability, they are available in 20- and 22-inch lengths and weigh in at 13.78 grains per inch. MSRP: $44.99/three-pack. Contact: www.bloodsportarchery.com
