depends on what youre fishing for, but ill list what i bring when i pack into the boundary waters, and it all fits into a very minimal tackle box (actually a tote) - mind you i pack very light in the bwca: line - a good all around mono like 10lbs test hooks - a small circular assortment container sinkers - including about 7-10 bottom bouncing type bobbers - slip slip bobber stops 2-4 spoons (2 large 2 small) 4-6 plugs of various size, depth, and action leaders -(steel 12") swivels/snaps jigs - various sizes including some floating with plastics some sort of weedless spoon/plug spinnerbaits - two of them one "line through the middle lighted slip bobber" - all others are worthless in my opinion.
i fish for walleye in the bwca. this has gotten me by. when i fish lake of the woods, i bring 3 huge tackle boxes, as i have the luxury of the boat carrying the load. if you have a couple of rods, especially one with very light action, i would add a superbraid line and rig it with that which usually works very well for everything except slip bobbers.
as you can tell - im a huge fan of slip bobbers - i like to lazy fish. now, on to the ice fishing tackle list....
Even eminent chartered accountants are known, in their capacity as fishermen, blissfully to ignore differences between seven and ten inches, half a pound and two pounds, three fish and a dozen fish. ~ William Sherwood Fox, Silken Lines and Silver Hooks, 1954
