The primary ability of the Byakugan gives the user a near 360º field of vision, except for one blind spot at the back of the neck above the first thoracic vertebra.[5] Upon activation of the dōjutsu, the wielder is granted an automatic 50 metre field of vision around themselves which can be extended through training[6][7] as Hinata Hyūga's range in Part II stretches to at least as far as 10 kilometres.[8]
The Byakugan is also able to see through solid objects and smokescreens,[9] even through most barriers as only a particularly strong barrier such as the Four Black Fogs Formation is able to somewhat distort the Byakugan's perception.[10]
It can also differentiate between non-corporeal clones and see through techniques that would otherwise hide an opponent from normal sight.[11] The dōjutsu also has the ability to follow high-speed movement.[12] In the anime, the Byakugan was also shown able to magnify objects to see the smallest of targets in the area and see in infrared to detect a target's body heat.[11]

didn't see your post sorry if you already said this or something to this degree
actually he was. He thought he had hashi down for the count then the real Hashi stabbed him through the back. Madara looked back down and the hashi he was talking to was a wood clone.
