Model size is listed by the outside diameter of the reel. Spool width describes the inside width of the spool. Reel weight is given in ounces without line installed. Our two trout models feature a preset Gear & Pawl drag system for spool control while paying out line to a running fish. The drag is designed to control the over-run of the spool with just a light drag to protect light tippets. Reels are precision machined from 6061-T6 Aluminum Alloy, 300 Series Stainless Steel and Silicone Bronze. Trout models cannot be retrieve converted, and must be ordered according to individual needs LHW or RHW.
