The Scan button is located on the right of the minimap.

Scan and Glyph icons are split up for spectators, showing both teams' cooldowns.
Players can use the Scan ability on the right of the minimap UI to detect any enemy heroes in an area.

Cooldown Manipulation[]
There is currently one source of Scan cooldown reduction.
The cooldown reduction is granted by the aura, not the item itself. This means using Scan while no one is affected by the aura (i.e. item owner is invulnerable and has no allies nearby), the cooldown is not reduced. Causes the Scan's cooldown to skip the first 105 seconds upon cast.
Scan cooldown gets reduced even when the player who activated it is not affected by the aura, as long as another ally is affected. This means a second Telescope does not reduce the cooldown any further.
- Radius: 1200
Scan Cooldown Reduction: 50%
Aura Linger Duration: 0.5
Aura, affects all nearby allies. Multiple instances of Prescient Aura do not stack.
