DELTA McKENZIE ShotBlocker has totally changed layered target technology. Shotblocker targets feature our patented welded-core technology that eliminates the need for platens, plates, cables, wires, straps or bands. What you get is a tougher target in which the layers or sheets can't shift, move or fall apart. They can be shot on all four sides, and best of all, the foam slivering that you get from most layered targets when shooting broadheads is greatly reduced. All this, plus easy arrow removal and integrated handle for easy transport! the travel Pro lets you practice anywhere you want to go. For bows up to 280 FPS. Not recommended for high poundage bows or crossbows.
