Can someone help me out here, I know this isn't even an answer choice...but why is it "sighted on" and NOT "seen on"?
"Sighted on" seems very awkward to me since I think of "sighted" as an adjective.
(of a person) Having the ability to see; not blind: "a sighted guide is needed"; "the blind leading the sighted, I thought".
Having a specified kind of sight: "the keen-sighted watcher may catch a glimpse".
Heads down, stay focused, ignore the noise
