MX Series Reels are precision machined 6061 T-6 marine grade aluminum and stainless steel components. Anodized for superior corrosion resistance and beautiful finish. Made of a true in one piece frame for the ultimate in strength vs. weight. Powerful lever drag system with adjustable strike pre-set Precision machined stainless steel gears Patented, indestructible, silent dog and gear anti-reverse system Reliable Avedrag dry carbon fiber drags for superior stopping power, smoothness and wear resistance Up to 9 lbs. of drag at strike, 14 lbs. full, while maintaining full free spool 8 sealed stainless steel ball bearings Alarm clicker Offset machined handle arm to reduce centerline profile and cranking wobble Large comfortable soft touch handle knob Specially designed rod mounting foot to fit most graphite trigger seats as well as standard rod seats Matching machined aluminum rod clamp Proudly made in the U.S.A. Avet casting reels (SX - HX) are grouped in "families" or "series" by size, more specifically by diameter, with the SX Series being the smallest, and the HX Series the largest. Within each series, there are different options and variations: Spool width ("J" or "jig" denotes a narrow spool, and "L" or "large" is a standard width spool, and "W" is a "wide" spool) Different retrieve speeds, (numbers with "." denote single speed gears while numbers with "/" denote 2-speed gears. Example: SX 5.3 = single speed, SX 6/4 = 2-speed) Increased drag output (Raptors) and magnetic anti-backlash cast control (M.C. Cast) are also options within a series
