Fishing Gear: Rods, Reels, Line, Hooks and Fish Finders Explained
What each piece of fishing gear does, which number on the box matters, and how to match rod, reel, line and hook to the fish you are after.
Fishing gear is sold by the aisle, but it is chosen by the number. A rod is a power rating and an action, a reel is a size and a gear ratio, a line is a diameter and a stretch figure, a hook is a gap and a wire gauge, and a fish finder is a frequency and a cone angle. Know the five numbers and the aisle stops being confusing: you can read any rod, reel, line, hook or sonar box and see what it is for. The pages below explain each number and give the ranges by fish; the recommendations are the consensus of manufacturer specifications, named reviewers and tournament anglers, cited on every page.
Start here
- Fishing rods — power, action and length, and which combination suits which lure.
- Fishing reels — spinning, baitcasting and spincast, sizes and gear ratios.
- Fishing line — monofilament, fluorocarbon and braid, compared on stretch, visibility and diameter.
- Fishing hooks — the aught sizing system, the hook types and the circle-hook rules.
- Fish finders — what the sonar frequencies show, and the Garmin, Humminbird and Lowrance ladders.
The five decisions
The defaults below are for the most common starting point, casting lures and bait for bass, walleye, catfish and light inshore fish from a bank, boat or kayak. Other fishing wants other numbers, and the table after this one says how far they move.
| Gear | The number that matters | Default for lure and bait casting | Why |
|---|---|---|---|
| Rod | Power (stiffness) and action (where it bends) | 7 ft (2.1 m), medium or medium-heavy, fast action | Bassmaster calls the 7 ft (2.1 m) medium fast “one of our most popular rod configurations because it’s so versatile” |
| Reel | Size (spinning) or gear ratio (baitcasting) | 2500–3000 spinning; 6.4:1 baitcaster | The 2500–3000 band covers bass, walleye and light inshore; 6.4:1 is the middle of the ratio range |
| Line | Diameter and stretch | 10–12 lb monofilament, or 15–20 lb braid to a fluorocarbon leader | Mono stretches 25–30%, fluorocarbon 10–15%, braid almost nothing; braid is a third to half the diameter for the same strength |
| Hook | Gap and size number | Sizes 2 to 3/0 for bass and catfish, 6 to 10 for panfish and trout | Sizes run from 32 (smallest) to 1, then 1/0 to 20/0 (largest) |
| Fish finder | Frequency and cone angle | CHIRP 2D with down imaging, 5–7 inch screen | 200 kHz reads about a third of the depth in width; 83 kHz reads about the depth |
The same decisions for other fishing
| Fishing | Rod | Reel | Line | Hook |
|---|---|---|---|---|
| Bass, walleye, light inshore (the defaults above) | 7 ft (2.1 m) medium-heavy fast | 2500–3000 spinning or 6.4:1 baitcaster | 10–12 lb mono or 15–20 lb braid | 2 to 3/0 |
| Trout and panfish, small water | 6–6.5 ft (1.8–2 m) light or ultralight | 1000–2000 spinning | 4–6 lb mono or fluorocarbon | 6 to 12 |
| Catfish, bottom fishing | 7–10 ft (2.1–3 m) medium-heavy, moderate tip | 4000–6000 spinning or round baitcaster | 20–30 lb mono or 30–65 lb braid | 2/0 to 8/0 circle |
| Carp, European style | 12–13 ft (3.6–4 m), 2.75–3.5 lb test curve | Big-pit or baitrunner 5000–8000 | 12–15 lb mono | 4 to 8 |
| Fly fishing | 9 ft (2.7 m), 5-weight for trout, 8-weight for bass and inshore | Fly reel matched to the line weight | Fly line plus a 9 ft tapered leader | 10 to 18 for trout flies |
| Surf casting | 10–12 ft (3–3.7 m) medium-heavy | 5000–8000 spinning | 30–50 lb braid to a 40–60 lb shock leader | 2/0 to 8/0 circle |
Each hub under this section carries the full ranges; the rods hub explains why a carp rod and a bass rod of the same power are two feet apart in length, and why a fly rod is measured in line weight rather than power.
What you actually need
The question everyone asks first is what you must have. The honest list is short. A rod and reel matched to each other, line that suits the water, a small box of hooks, weights and swivels, a licence and something to measure a fish with. Everything past that is a specialisation: a baitcaster when you start throwing heavier lures into cover, braid when you fish grass or need casting distance, a fish finder when you fish from a boat or kayak and want to stop guessing at depth and structure.
Price follows the same logic. The rod pages list reviewer picks from about fifty dollars to several hundred; the difference is sensitivity, weight and guide quality, not whether the rod catches fish. Reels scale from thirty-dollar spincasts to nine-hundred-dollar flagships, and the mid-tier Shimano and Daiwa models are where the tournament anglers and the review sites converge. Line is cheap enough to replace every season, and mono ages fastest.
Saltwater changes the answer
Every gear page notes where saltwater differs. Reels need sealed drags and corrosion-resistant bearings, increasingly sold with an IPX water-ingress rating. Rods get longer for surf and pier work. Hooks must be non-stainless circle hooks by law when fishing natural bait for Gulf reef fish, and several Atlantic states require them for striped bass. The saltwater specifics live on the relevant pages rather than in a separate section, so one page answers the question for both waters.
Where to go next
The lure section is the other half of the tackle question: the rod, reel and line pages here say what to match to a chatterbait or a drop shot, and the lure pages say how to fish it. The species pages close the loop by naming the tackle each fish calls for.
