Magnus is a popular wet fly pattern for seatrout fishing in saltwater. It was originally designed in Denmark. It has ball chain eyes which give nice jiggy action in the water. Magnus is general attraction fly which does not imitate any particular food sources of seatrout, though its outlook works best when fish are feeding with shrimps and sticklebacks. Try as well for put & take fishing in ponds or Lapland's trout and grayling lakes.
