What I read into what people are saying when they refer to "single poling" is they're not Spider Rigging, Pushing, Pulling, or Longline Trolling with multiple rods ... sort of "distinguishing" themselves as being more "sporting" than the people that do use multiple rods at the same time. Then there's the one's that "two pole" fish, one rod in each hand (usually vertical jigging).

In any event ... all these descriptions are simply a way to distinguish between fishing methods & presentations.
