BD has evolved this technical, all-terrain tool with a new hydroformed shaft to increase stiffness and reduce weight, while maintaining exceptional clearance. Hydroforming uses pressurized water to expand the Viper's shaft into its uniquely stiff, yet lightweight shape. With superb balance, leashless capability and an optional integrated Android Leash, the Viper goes most anywhere. Comes equipped with our Viper Fang and Strike, to cradle your hands for precise gripping when going leashless. Laser Pick included. Patented.
