The FWX series replaces the FW series that has successfully satisfied fly fishers for the last 5 years. The FWX reels differ from the FW series in that they are almost a half ounce lighter due to their new spool design, making them the lightest machined aluminum disc drag fly reels in the market. Like the NVG reels, the FWX has a Giga arbor design that promotes faster line pick up and backing drying. In addition to the advanced spool designs used in these reels, they have added a new stainless steel 1-way clutch that is housed in our proprietary TORQ-X clutch drive that ensures instant drag engagement with no slack, allowing the retrieve direction to be easily switched, and they have converted the new reels to be push on and click tab release. Finally, one of our newest creations to come out of the Nautilus think-tank is an industry first LaserID line identification system: They have laser etched a white spot on the back of each FWX spool so that you may write the line type and weight that you are using on that spool. Write it on with a permanent marker and wipe it off with alcohol when changing lines. Also good to use to write your name or phone number in case you lose the reel. No more washed out or lost line stickers!
