Penn Fathom Level Wind Reels contain Line Capacity Rings which eliminate the question of how much line you have left when fighting a fish. The three lines on the spool flange let you know when you have 1/3rd, 2/3rd, or a full spool of line. Also, if you respool often these lines give you a benchmark for backing your superlines with monofilament which will help eliminate wasted time and lines. Features include: Full metal body and sideplates, Marine-grade bronze alloy main gear, Precision-machined stainless steel pinion gear, Versa-Drag system with HT-100 washers, 3 shielded stainless steel ball bearings, Instant anti-reverse bearing with silent back up ratchet, Stainless steel TiN coated levelwind system, and Reversible Harness Lugs on 40 & 60 sizes.
