This is not an easy topic, at least not to me. >.>
I don't like voting on something that I'm not too sure about. If we can see such a scenario even in a game (see below), I would be okay if the results since I feel in this case, it can go either way.
People are voting No because they feel Telescope technique does not allow you to see the appearance/location of the Jinchuuriki while people who are voting Yes think the tech can.
I'm voting
Yes because I don't believe in either of the choices, but the fact that there are not really a lot of ways to sense a bijuu (Byakugan and Sage Mode are KGs and Mind's Eye of Kagura is Uzumaki-only). So what will a shinobi who has NO access to any of those methods do? Force to team up with someone who does? (I guess that's what Bocc and Rusaku did)
So again, I'm voting Yes to give the common/ordinary shinobi a chance at least.

Random (but related) find that I thought was okay to bring up here.
Discovered this from the Telescope Technique wikia (ironic?).
http://naruto.wikia.com/wiki/Naruto_Shipp%C5%ABden:_Kizuna_DriveSo in the Naruto Shippūden: Kizuna Drive game, Hinata sees 30 km away and Neji is able to 'see' within a bijuu.
Hinata sees a strong chakra 30 km away.

I just find it funny that this happened in a game
a few years before Naruto: The Last or Boruto the Movie came out.
