Hawkeye

The Hawkeye is an item in Twilight Princess which lets you see farther away than usual. It is similar to the Telescope in The Wind Waker. You can combine it with the Hero's Bow to be used as like a sniper. The Hawkeye is a one of a kind item that can only be purchased at the Malo Mart in Kakariko Village after completing the bow minigame. It is an optional object and is not required to complete the game. You find it after talking to Talo in the top of Kakariko Village and finish the mini game.
