"The Excalibur Trailblazer Mechanical Crossbow Broadhead gives crossbow hunters outstanding long-range accuracy, deep penetration upon contact, and massive blood trail performance. A perfect combination of fast, accurate, and deadly, the Trailblazer flies true on a flat trajectory with zero planning and less drag before opening to deliver a big 2"" cutting diameter. Made of a heavy-duty aluminum, this sturdy broadhead is topped with a cut-on-contact chisel tip that explodes through hide and bone on impact. Extreme accuracy design employs Excalibur's dynamic blade control system to control each blade expansion independently without any O-rings or bands. Designed for arrow speeds up to 500 fps, this system also adjusts to resistance during penetration to prevent blade breakage.
