But I think the problem most of are having are the words, "finds and tracks"

I understand loud noises over great distances, or sound channels carrying intermittent sounds great distances. Detection is not the problem, tracking is. But isn't one of the problems with tracking through the deep sound channel the fact that range (Other than "It's really effing far way cap'n") is practically impossible to tell since it's actually based on some sort of harmonic? IE, the contact would be a possibility of ranges of multiples of say 30 miles, ie it could be at 60. 90, 120, or 150 miles, etc?
