Fishing gear guide

General, method-neutral guidance on what the main categories of tackle are for. None of this is country- or species-specific advice - check a spot's own page and the legislation page for your country for anything with a legal dimension, like landing-net or barbless-hook rules.

Rods

A rod's job is to cast the terminal tackle out, absorb the shock of a fighting fish, and give you feel for what's happening at the other end of the line. The right rod depends on the method more than the species:

Spinning rods - light-to-medium rods with a sensitive tip, designed to work with fixed-spool reels and lures (spinners, soft plastics, small crankbaits). Typically 1.8-2.7m. Used for predator fishing and general lure work.
Baitcasting rods - stiffer-actioned rods paired with a baitcaster reel sat on top of the blank. Favoured for heavier lures and precision casting around cover (weed, snags, structure), common in predator and bass-style fishing.
Fly rods - very light, long, flexible rods designed to load and cast the weight of the fly line itself rather than the fly, since a fly weighs almost nothing. Rated by a line-weight number (commonly #3-#4 for small stream trout up to #9-#10 for salmon or saltwater work) - matching rod weight to line weight is the core of fly-rod selection.
Sea/beach rods - long (3-4.5m), powerful rods built to cast heavy leads a long distance from open shore and stand up to surf and larger fish. Stiffer through the middle and butt than freshwater rods.
Carp rods - medium-length (3.3-3.9m), progressive-action rods built for casting a baited rig a set distance repeatedly and cushioning long, powerful runs from big, hard-fighting fish. Often used in matched sets of two or three on rod pods.
Feeder/method rods - quiver-tipped rods for coarse/float-adjacent ledger fishing, where the soft tip visibly registers bites from feeding fish rather than relying on a float.

Rod "test curve" or "casting weight" ratings (printed on the blank) tell you the range of lead/lure weight the rod is built to cast and cushion - going well outside that range risks either poor casting or a snapped rod.

Reels

Fixed-spool reels - the most common general-purpose reel. Line pays off a fixed spool via a rotating bail arm, giving good casting distance with minimal tangling. The default choice for spinning, coarse, feeder and most sea fishing.
Baitcaster reels - the spool itself rotates as line pays out, giving more direct control and better accuracy for experienced users, but with a real risk of "bird's nest" tangles (backlash) if the spool isn't controlled properly during the cast. Common in predator/bass fishing with heavier lures.
Fly reels - mainly a line-storage device rather than a casting tool, since in fly fishing the line is cast by hand, not the reel. Its main working job is providing smooth drag once a big fish is running.
Multiplier reels - a larger, more powerful relative of the baitcaster, mounted on heavier sea or big-game rods for casting heavy leads long distances or winning against strong fish and current.

Reel "gear ratio" (e.g. 5.2:1) describes how many times the spool turns per handle turn - higher ratios retrieve line faster, lower ratios give more cranking power, relevant mainly for lure and predator fishing where retrieve speed matters.

Line

Monofilament (mono) - a single extruded nylon strand. Cheap, has useful stretch that absorbs sudden shock and forgives hook-pulls, and is easy to knot. Downsides: more stretch means less bite-detection sensitivity, and it degrades with UV/age more than braid.
Braid - multiple fine strands woven together. Very thin for its breaking strain, virtually no stretch (excellent bite detection and hook-setting power at range), and very durable. Downsides: more visible in clear water (often paired with a fluorocarbon leader), can be harder to knot reliably, and has almost no shock-absorption of its own.
Fluorocarbon - similar refractive index to water, making it much less visible underwater than mono. Sinks faster than mono, is more abrasion-resistant, but is stiffer and usually more expensive - commonly used as a leader material tied to a braid mainline rather than as a full spool of mainline itself.

Line "breaking strain" (marked in lb or kg) should be matched to target species and terrain - too light and a big fish or snag breaks you off, too heavy and casting distance/bite detection both suffer for no benefit.

Terminal tackle

Hooks - sized by a number system where, confusingly, a larger number means a smaller hook (a size 18 is tiny, a size 2 is large) until sizing crosses into the "/0" range (1/0, 2/0...) used for bigger hooks, where a larger number means a larger hook. Barbless or micro-barbed hooks cause less damage and are easier to remove - some venues require them by rule, check the spot's own page.
Weights/leads - add casting weight and/or hold a bait or rig in place against current or drift. Common shapes include swan shot and bombs (freshwater ledgering) and grip/breakaway leads (sea fishing in tide or surf, designed to dig in and hold bottom).
Floats - suspend bait at a set depth and visually signal a bite. Waggler floats (attached bottom-only) suit calmer stillwaters; stick floats (attached top and bottom) suit trotting a bait down a flowing river; larger, more buoyant floats handle bigger baits or windier conditions.
Swivels - a small rotating link between line and rig, or between mainline and leader, that stops the line twisting under the turning motion of a retrieved lure or a fighting fish.

Landing and handling gear

General good practice, not a substitute for a spot's own posted rules: a landing net with a soft, knotless mesh reduces damage to a fish's fins and slime coat compared to an old knotted net. An unhooking mat gives a fish a padded, wet surface to rest on briefly out of the water. Forceps or artery clips let you remove a hook quickly without excessive handling. See the catch and release page for how to put this gear to use once a fish is landed.
