Retrieve calculator
Type a spool diameter and a gear ratio, or tap a preset. The number is the most line one handle turn can bring back on a full spool.
One handle turn spins the rotor gear-ratio times; each rotor turn lays one wrap around the spool. On a full spool that wrap is the spool's circumference, so: max retrieve = π × spool diameter × gear ratio. (Circumference, not area — π × d, not π × r².)

Finesse Reel (BFS)
A reel built to cast 1-5 g lures 20-30 m with ease — a bait-finesse low-profile, a BFS round reel or an ultralight shallow-spool spinning reel; the recreational, stream-and-pond class rather than a tournament tool.
