These 20 foot divers are a great way to broaden your trolling spread, pull these farther behind the boat in the center positions and you'll have a good chance of catching anything from offshore pelagic species or your nearshore favorites. This size works especially well for yellowtail trolling in the local waters, but they'll work for smaller yellowfin and bluefin down south. You can't troll them pretty quick up to 12 knots or so but usually going slower gives better results.
