This refers to a specific type of sight commonly utilized in archery, particularly on compound bows. It features three aiming points, or pins, arranged vertically within the sight housing. The “slider” component indicates that the entire sight housing can be adjusted vertically along a track. This allows the archer to compensate for varying distances to the target beyond the yardages represented by the fixed pins.
These sights offer a blend of quick target acquisition provided by multiple fixed pins and the extended range capability found in single-pin adjustable sights. Their popularity stems from a perceived balance between speed and precision, making them suitable for both hunting and target archery applications. Historically, archers relied on instinct or estimating hold-over for longer shots; the introduction and refinement of adjustable sights with multiple pins greatly enhanced accuracy at varied distances.
