The Underwater
Fishing Guide
A complete beginner's guide to finding and catching fish — and to seeing what you have been guessing at for years.
Most fishing advice starts with what to buy. This guide starts with a harder question: where are the fish, and why are they there? Everything else — rod, line, knot, lure, retrieve — is downstream of that one answer, and almost every blank day comes from getting it wrong.
It is a full beginner's course in freshwater fishing: gear that genuinely matters, the three knots worth learning, how to read a lake and a river, the five rigs that cover nearly every situation, what each species actually does, and how to handle and release a fish properly. It is also the only beginner's guide written on the assumption that you can see underwater.

1 Gear that actually matters
Tackle shops sell complexity. Fish do not care about most of it. If you are starting from nothing, three decisions matter and the rest can wait a season.
The rod
One rod covers most freshwater fishing: a 6′6″ to 7′ medium-power, fast-action spinning rod. Medium power means it has the backbone to set a hook and fight a decent fish; fast action means the top third bends while the rest stays stiff, which gives you both casting feel and hook-setting power.
Buy the cheapest rod from a brand you have heard of. A $40 rod and a $300 rod catch the same fish; the expensive one is lighter and more pleasant over an eight-hour day. That is a real benefit, but it is not a catching benefit, and it is a poor first purchase.
The reel
A 2500-size spinning reel balances a 6′6″–7′ medium rod almost perfectly. Spinning gear is the correct choice for a beginner: it casts light lures easily and it does not backlash. Baitcasting reels are better for heavy lures and thick cover, and they will punish you with tangles for the first fifty casts.
The one spec worth checking is a smooth drag. Set it so line pulls off under firm hand pressure — roughly a quarter to a third of your line's breaking strain. A drag set too tight is the most common cause of a lost fish.
The line
This is the decision that actually changes your catch rate, and the one beginners get wrong most often.
| Line type | Strengths | Weaknesses | Use it when |
|---|---|---|---|
|
Monofilament 6–10 lb |
Cheap, forgiving, stretches, floats, easy to knot | Stretch dulls bite detection at depth; degrades in UV | Your first spool. Panfish, bait, topwater. |
|
Fluorocarbon 6–12 lb |
Nearly invisible underwater, sinks, abrasion-resistant | Stiff, pricier, less forgiving of a bad knot | Clear water, spooky fish, as a leader. |
|
Braid 10–30 lb |
No stretch — you feel everything; thin; lasts years | Highly visible; needs a leader; slips in some knots | Deep water, heavy cover, jigging. |
What to skip
- A tackle box of 200 lures. You will fish four of them.
- Scent sprays and attractants. Marginal at best.
- A second rod, before you have used the first properly.
- Anything sold as a "kit" at a supermarket. The rod is usually fine; the reel usually is not.
