Excalibur All Crossbows Beacon Nock Features The Excalibur Crossbow All Crossbows Beacon Nock uses an ultra-bright red light that triggers automatically the instant the bolt is released giving shooters a clear illuminated path to follow toward the target. This immediate activation means there is no fumbling with a separate switch before the shot so the nock is ready every time the crossbow fires. The light continues to mark the arrow s position after impact which speeds up arrow recovery in low-light conditions thick cover or after dark. An exclusive easy-off deactivation switch lets the shooter quickly shut the light down once the arrow is retrieved conserving battery life for the next outing. Built from aluminum for durability the Beacon Nock is sized to fit all carbon arrows with a .300 inch inside diameter making it a simple upgrade for shooters who already run standard carbon shafts. It is compatible with the full Excalibur crossbow lineup excluding the Hybrid X so most Excalibur owners can add it without hunting for a specialty fitment. Sold in a 3 pack it gives hunters and target shooters enough nocks to outfit multiple bolts for a single trip afield. Whether used for bowhunting or practice sessions the Beacon Nock adds a practical visual aid that helps shooters track flight and recover their investment in quality arrows.
