1.Thicker than the original model, the main body weight reduction thickening increases the overall strength. 2.The main seat plate is riveted with SUS304 stainless steel, it is much stronger and harder than the screw. (Original seat plate is easy to loosen). 3.The main body and cover are locked with SUS304 stainless steel thick screw and Teflon Paste, the thick screw is extra-stronger, and the Teflon Paste can prevent the looseness. (The original model is M2 screw with poor locking strength and easy to loose without Teflon Paste).4.One-Piece cold forged and machined of main cover and one-way bearing seat increased the strength and precision. 5.The wrench design is hide the crisp and loud sound structure, and the brake is adjusted to three gear positions FREE/STRIKE/FULL. 6.Replace the NMB Japan imported bearings which have been enlarged. (the original bearing is small and poor strength). 7.Changed from two ordinary 6-pin one-way bearings to 11-pin metal shrapnel long one-way bearings (static tension can be 46LB), which increases the tensile force value and strength of one-way force. 8.Increased reactionary ratchet to prevent one-way bearing failure. 9.Stainless steel easy-to-cut helical gear , helical tooth is high strength and small noise.high gear ratio choice from 5.7:110.The handle is change from screw to stainless steel rivet, it is strength and not easy loose. 11.The brake adjustment button is changed to the sound structure, which improves the adjustment precision and the sense of passage. 12.The small-line capacity reel is changed to the large-line capacity, the bigger capacity can be deep-water fishing. 13.Double brakes in a good design and processing precision make it more smooth.
