The XB30 Zoom FFP from Hawke Optics revolutionises what can be done with crossbow optics. Thanks to the First Focal Plane (FFP) optical system, users can now Zoom in and out through the entire magnification range of the scope and trust that the distance markers on the reticle are correct. Traditional crossbow scopes require the user to set the scope's magnification ring to match their crossbow speed - this limits the usability of the crossbow scope and means you are always fixed on one magnification power. With the XB30 Zoom FFP you unlock the full potential of the crossbow scope and can use the low zoom setting for close shots and the high zoom setting for long range!
