"The Byakugan will be able to see you quite clearly as it can see through solid objects. So Byakugan users will be able to plainly see you. Now, Sharingan and Rinnegan. Both act the same and are able to detect chakra. So what does this mean? Well basically both dojutsu have a dual vision in a sense in that they have regular eye sight and a chakra 'infrared' eye sight. You'll learn more about that if you ever train in the Sharingan. Anyways, basically they can detect you. You aren't far enough in the earth to pick up on your location. They will see your chakra. And because of that will know where you are and be able to easily kill you with say...Swamp of the Underworld. So, there are a lot of dangers to Hiding Like a Mole as you can see. It isn't even limited to these. So I recommend being very careful when you use this technique against a versed opponent. Anyways, any questions?"
