Spyglass is a technology in Age of Empires IV that can be researched at the Stable in the Imperial Age. It is available for every civilization. Once researched, the radius of Line of Sight of Scouts is increased by 30%, increasing its area of vision by 69%.
Note: The actual increase in Line of Sight radius appears to currently be much greater than 30%. Whether the description or effect is wrong is unclear
