Abstract

An archery bow sighting device is disclosed which includes a body member as well as a vertical adjustment block and a longitudinal adjustment arm and a lateral adjustment bar which, as interconnected and interlocked with respect to one another, provide three complete degrees of freedom of a grouping of preset pin blocks each carrying pins to allow sighting for facilitating archery accuracy. The interlocking adjustment members are each selectively capable of being fixedly secured to prevent adjustment of any one, two or three degrees of freedom of movement. The sighting pins themselves are individually adjustable such that when the relative spacing between each sighting pin is finally achieved, they can be moved as a group, vertically, laterally, or longitudinally thereby preventing the necessity of adjusting each and every individual pin position when the archery conditions change such as a variation in wind, lighting, or other indeterminable factors.
