well to be honest most sensor use some kind of chakra signatures to detect a person whereas Ninetails chakra mode enables sense of an emotion so if BZ has some ill intent he should be easily detected by naruto...... I believe if Naruto uses SM he cannot sense BZ since BZ was able to attack TTJ madara from blindspot..... And yes I think it would be safe to assume that naruto's sensing abilities are beyond other sensor since he can sense an emotion rather than some random chakra signature which can be easily hidden.
