02Reels

Reels

The two most common lure reels are the spinning reel and the baitcasting reel. The fundamental difference is whether the spool turns when you cast, and that determines how they feel, what they're good at and how hard they are to learn.
ASpinning vs Baitcasting

Two Kinds of Reels

SpinningBaitcasting
SpoolStays still on the retrieve and the cast while the rotor wraps line around it; turns only when the drag slipsTurns as line goes out / comes in
How line leavesSpirals off the front of the spoolPays straight out as the spool turns
MountingUnder the rod (spinning rod)On top of the rod (casting rod)
BacklashBasically never, but prone to line twist and loose loopsYes; needs brakes and thumb control
Light luresExcellent; even lures of a few grams cast farFair; dedicated BFS models can cast 2–7 g
Accuracy & efficiencyRequires finger control of the line and flipping the bailThumb controls the line at all times for pinpoint accuracy and fast cast-to-retrieve transitions
PowerDepends on size; big spinning reels can have huge drag, but at the same size they're less comfortable for working heavy line and heavy lures all dayDepends on size; the straight line path and greater cranking torque make heavy line, heavy lures and pulling fish out of cover easier
Basics★★★★★★★★

There are also round baitcasters (round-frame reels with large line capacity and rugged build, for big lures and saltwater) and spincast reels (push-button reels with a closed face, rarely seen in China).

Animation is slowed down. On the retrieve the spool moves back and forth (oscillation) to lay line evenly. The filled spool diameter is estimated at about 44 mm for a 2500 size.

How to Use It

  • Casting: hook the line with your index finger → open the bail → swing the rod and release your finger at the power point → as the lure nears the target, touch the spool lip with your finger to slow it (feathering) → after splashdown, close the bail by hand.
  • Line twist: every wrap a spinning reel puts on adds a little twist, and spinners, crooked soft plastics and reeling while the drag slips all make it worse. Closing the bail by hand, keeping tension on the line while reeling and using swivels all reduce twist and loose loops.
  • Don't crank while the drag is slipping: the spool is turning backward to give line while the rotor keeps wrapping, so the line gets twisted as it pays out, causing severe twist.
  • Fill line to about 1–2 mm from the spool lip. Overfilled spools shed loops; underfilled ones cut casting distance.

Why Does It Backlash?

On the cast, the lure pulls the line and spins the spool. In the air the lure is constantly slowed by drag and gravity, while the spool's inertia wants to keep it spinning at the same speed. When the spool releases line faster than the lure can take it, the extra line balloons up and tangles on the spool: that's a backlash (bird's nest). It's most likely at release (the spool is suddenly accelerated), into the wind (the lure slows faster), with light lures (little inertia, quick to slow) and at splashdown (the lure stops suddenly).

A simplified physics model; the numbers only show trends. When the spool (vermilion) spins faster than the lure (ink) flies, the extra line piles up on the spool. Stronger braking makes backlash less likely but shortens the cast.

Brake Systems

Centrifugal Brake

Centrifugal brake

Brake blocks inside the spool slide outward under centrifugal force and rub against a brake ring. Centrifugal force rises with the square of spool speed, so braking is strongest at high speed and almost nothing at low speed.

Strong control early in the cast, then it lets the spool run, so it casts far with smooth line flow. You adjust it by opening the side plate and switching brake blocks on or off (some also have an external dial).

Magnetic Brake

Magnetic brake

Magnets near the spinning metal spool create eddy currents, producing drag roughly proportional to spool speed. The external dial changes the distance between magnets and spool.

It works through the whole cast, still braking at the end and just before the lure lands. Forgiving and easy to adjust; great for beginners and light lures.

Digital Control

Digital / DC brake

The spinning spool generates power; a chip reads spool speed in real time and brakes through an electromagnetic coil, applying different braking curves at different stages of the cast (e.g. Shimano's DC system).

Best at handling headwinds and preventing backlash; you pick modes for the lure and conditions. Expensive.

The digital brake curve is only illustrative; actual braking curves are set by each manufacturer's control program.

Setup Steps (Beginners)

  1. Start with the brake set on the strong side (magnetic dial a bit above the middle).
  2. Set the spool tension: hold the rod level, press the thumb bar and let the lure drop; adjust so the spool stops right when the lure hits the ground. Some modern baitcasters recommend using tension only to remove side-to-side spool play and relying mainly on the brakes; check the manual.
  3. Make gentle test casts with your thumb lightly on the spool; gradually reduce the brake until you only need an occasional light thumb.
  4. Increase the brake for lighter lures, stronger headwinds, or when switching to sidearm casts or pitching. At splashdown, always stop the spool with your thumb.
Got a backlash?

Immediately stop the spool with your thumb → press the thumb bar, hold the line on the spool with your thumb, and slowly pull out the loose line → find the loop that's “biting” and pick it loose. If a loop is buried deep, hold the spool, reel in a few turns, then make a gentle cast; that often pulls it free.

Sizes

TypeUse
BFS / micro baitcasterUltralight spool that casts 1–7 g lures; streams, finesse plastics
70–100 size (common)All-round freshwater, 7–30 g lures; the workhorse for bass
150–200 sizeMore line capacity and power: heavy braid, heavy lures, snakehead frogging, big baits
Round baitcasterBig swimbaits, saltwater and big fish

Left/right-hand retrieve refers to the handle side: with a left-hand reel you crank with your left hand and cast with the rod in your right, so you don't switch hands after the cast. Very common in China.

DGear Ratio

Gear Ratio & Retrieve

Gear ratio (e.g. 7.1:1) is how many times the spool (the rotor on a spinning reel) turns per turn of the handle. What really determines retrieve speed is line recovered per turn: gear ratio × π × effective spool diameter. Spinning reels have wider spools, so their gear ratio numbers are lower (typically 4.x–6.x), but they don't necessarily recover less line per turn.

ClassGear ratio (baitcaster)Per turnBest for
Low gear5.0–6.2 : 1~50–65 cmHigh-resistance lures like deep crankbaits and big-blade spinnerbaits; less effort, slow and steady retrieve
Medium gear6.3–7.2 : 1~65–75 cmAll-round: minnows, VIBs, most hard baits and soft plastics
High gear7.3–8.x : 1+~75–90 cm+Texas rigs, jigs, frogs, etc.: pick up slack fast, set the hook fast, drag fish out of cover

Effective spool diameter means the outside diameter with line on it: less line means a smaller diameter and less line per turn. Baitcasters in the 70–100 size are typically about 30–36 mm; 2500 spinning reels about 40–46 mm.
EDrag

Drag

The drag is a set of friction washers inside the reel: when a fish pulls harder than the setting, the spool slips and gives line so it doesn't break. Spinning reels adjust it at the front of the spool (front drag) or the back of the body (rear drag); baitcasters use the star drag next to the handle. The “max drag” in the specs is only an upper limit; in practice you'll use far less.

5.4kg
Suggested drag
1.4–1.8kg
Rule of thumb: 1/4 to 1/3 of the line's rated strength. With braid + leader, go by the weakest link (usually the leader or the knot).
  • For precise setting: run the line through the guides to a spring scale, bend the rod to a fishing angle and pull, then read the force at which line starts to slip.
  • Without a scale: pull the line by hand; it should take a firm pull to get steady line out. Err on the loose side.
  • Single-hook plastics in cover need a tighter drag to pull fish out; treble-hook hard baits and thin-mouthed fish (like topmouth culter) call for a looser drag.

Other Specs

Weight
Lighter is less tiring, but balance with the rod matters more: it's most comfortable when the balance point is near the fore grip.
Bearings
“X + 1 bearings” is just a count; quality, placement and overall build matter more than the number.
Line capacity
Marked like “PE 1.0–150 m” or “12 lb–100 m”, meaning how much line of that size the spool holds.
Waterproofing / saltwater
Rinse with fresh water and dry after saltwater use; some models have sealed designs.
