As I understand it, "Pop Gear" is a brand name, but in common usage has become the generic label for all gang trolls. I remember Jack Lloyd's, Jack o' Diamonds and several others. My Dad used to call all of them "yard and a halfs", because that's how long they used to be.

All of these are undeniably one of the most effective/productive lure combinations for putting fish in the boat, but not too much fun to play a fish on.
