The new Hind Sight Magnum features a 28% larger Sight Ring for a greater field of view. The Patented Cross Hairs are thicker in depth making them sturdier for those hunts in rugged terrain. The larger surface area of the Cross Hairs also allow them to absorb more light when charging for greater visibility in low light. The new Magnum is of a universal design and is compatible with most bows and front sights made today.
