The American-made Spitfire DoubleCross is a 100-Grain Broadhead that integrates four, no-fail blades with two-stage blade deployment. Spitfire's bulletproof design keeps the blades closed in flight and only open on impact, no matter how fast the arrow is traveling. The front deploying "stage one" main blades boast a massive 1-7/8" cutting diameter while the rear deploying "stage two" 'bleeder' blades feature a 1-1/18" cutting diameter. The DoubleCross cuts vertically and horizontally, regardless of the angle of impact, delivering better entrance and exit wound channels and increased blood trails. The trophy tip delivers bone-splitting penetration.
