Shimano Nasci FB 500 Line Capacity & Reel Setup Guide
If you are setting up the Shimano Nasci FB 500 for light-line panfish, trout and ice fishing, its 4 lb / 100 yards mono rating is a useful starting point. The 5.6:1 gearing takes up 27 inches of line per crank for retrieving small lures and picking up slack. Choose your exact line in the preloaded calculator below to estimate a full spool or optional backing beneath a shorter working length.
Quick Answer: Best Line for the Shimano Nasci FB 500
Best overall range: 4-8 lb braid
Simple alternative: 2-6 lb mono/fluoro
4-8 lb braid is a ReelCalc starting suggestion for this setup. For a straight main line, consider 2-6 lb mono/fluoro. Match the strength to your rod, presentation and cover; backing is optional.
Who Is the Shimano Nasci FB 500 For?
This size is a starting point for light-line panfish, trout and ice fishing. Choose the working line for the rod and presentation first, then allow a useful reserve for the fishing you expect. This page follows NAS500FB (FB (2016 family; this size introduced 2018)); a similarly named model or another generation can have a different spool.

Best Line Setup for the Shimano Nasci FB 500
Start with a line strength suited to your rod, lure or bait, and the cover you fish. You can fill the spool with main line or use optional backing under a shorter working section. Keep steady tension while spooling and watch the fill level.

Shimano Nasci FB 500 FAQs
What Size Braid Is Best for the Shimano Nasci FB 500?
4-8 lb braid is the practical ReelCalc range for this reel. Use the lighter end when fishing small lures for trout and panfish in open water. The upper end can provide more margin around light cover, but keep the line matched to the rod and lure so the setup still handles light presentations well.
How Much Line Does the Shimano Nasci FB 500 Hold?
One published reference for this model is 4 lb / 100 yards mono. The full table above shows the other listed capacities. Select your exact line to estimate the fill, then watch the spool clearance instead of forcing on the last few yards.
