Hook a school of tuna with your lures running clean and well-spaced, and outriggers feel like the obvious answer. Watch fish mark deep on the sounder while your spread skips uselessly on top, and suddenly the downrigger starts making a lot more sense. That is the real story behind downrigger vs outrigger fishing - they solve different trolling problems, and choosing the right one depends on depth, spread control, target species and the way you fish your local water.

Downrigger vs outrigger fishing: the core difference

A downrigger is built to present a lure or bait at a controlled depth. It uses a cannonball or bomb weight clipped to your line, letting you troll well below the surface and stay in the strike zone for fish holding deep. If you are marking kings on bait balls, working deep for trout, or trying to keep a lure down where the water temperature is right, a downrigger gives you precision that flatline trolling cannot.

An outrigger does a different job. It spreads your lines wider from the boat so multiple lures can be trolled cleanly without tangling. That is why you see outriggers on game boats pulling skirted lures, garfish, diving minnows and teasers for tuna, marlin, mahi mahi and other pelagics. They are about spread management, lure presentation and keeping more lines fishing effectively.

So if you want the short version, a downrigger controls depth, while an outrigger controls width and lure separation. Neither is automatically better. They are tools for different styles of trolling.

When a downrigger makes more sense

If your fish are not feeding high in the water column, a downrigger can change the whole session. This is especially true when the sounder is telling you one thing and your surface lures are doing another. In those situations, sending a lure to a measured depth is not just handy - it is the difference between trolling hopefully and trolling with purpose.

South Australian anglers know this can matter when kings hold deeper around structure or bait schools are sitting below the obvious surface activity. It also matters in freshwater and estuary situations where fish stack up at a certain depth band and stay there. Rather than guessing with lead-core, snap weights or oversized diving lures, a downrigger lets you set depth more accurately and adjust quickly.

Another advantage is cleaner lure action. A lot of lures work best when they are not overloaded with extra weight in the line. With a downrigger, the lure runs free once it pops from the release clip during a strike. That can mean a more natural presentation and a cleaner fight.

The trade-off is complexity and drag. You are adding hardware, weight and one more system to manage around the transom. On a smaller trailer boat, deck space matters. So does ease of reset when the bite is on and people are moving around with rods, nets and gaffs.

When an outrigger is the better tool

If you troll multiple lines for pelagics, outriggers quickly earn their keep. Their job is to pull line entry points away from the boat, opening your spread and reducing tangles in turns, in sloppy water, or when a fish crosses lines. A cleaner spread means each lure has room to work properly instead of blowing out, tracking badly or fouling another line.

This matters most in bluewater trolling. If you are pulling skirts for tuna or setting a pattern for marlin, lure position is everything. Short corner, long corner, short rigger, long rigger - each lure has a place in the wash and should behave consistently. Outriggers help keep those positions repeatable.

They also let you fish more lines effectively. Without them, a multi-lure spread on a modest boat can become a headache, especially in quartering seas or when turning onto fish. With outriggers, the boat fishes bigger than it is.

The limitation is obvious enough - outriggers do not get your lure deep. They are surface and near-surface spread tools. If fish are feeding well down in the water, a perfect wide spread still might not reach them.

Downrigger vs outrigger fishing for Australian species

The species you are chasing usually answers the question faster than any gear catalogue can.

For tuna, outriggers are often the first choice because they suit classic trolling spreads with skirts, hardbodies and skip baits. Surface-feeding or mid-water pelagics respond well to well-spaced lures, and outriggers help keep those lures where they should be. If you are covering ground and hunting active fish, that wider spread is valuable.

For kingfish, it depends more. If fish are high, working bait schools or smashing livebaits near the surface, outriggers may be useful in a broader trolling setup. But if kings are holding deeper around reefs, wrecks or bait schools, a downrigger can be the smarter tool because it puts a livebait or lure right in front of them.

For trout and some freshwater trolling applications, downriggers have a clear advantage. Those fisheries often demand exact depth control, and outriggers simply do not solve that problem.

For marlin, outriggers are part of the standard system on many boats because lure spread matters so much. You are not trying to pin one lure to 12 metres. You are trying to run a disciplined pattern in the wake.

Boat size, crew and practical setup

A lot of anglers get caught up in what looks professional rather than what fits their boat. That is a mistake. The best system is the one you can deploy, reset and fish properly without turning your deck into chaos.

A downrigger can be a very practical addition on a smaller boat if your fishing style suits it. One or two rods, one or two downriggers, a sounder and a clear plan - that is manageable. It is also well suited to anglers who fish solo or with one mate, because the system is focused and deliberate rather than spread-heavy.

Outriggers make the most sense when your boat and crew can support a proper trolling pattern. That does not mean you need a large game boat, but you do need enough room and enough control to run several lines safely. Folding or telescopic outriggers can suit smaller trailer boats, but they still need to be matched to the vessel and the style of fishing.

If your current problem is line tangles, lure crowding and poor spread shape, outriggers are likely the answer. If your current problem is fish sitting at 8 to 20 metres while your lures run on top, start looking at downriggers.

Gear considerations that actually matter

The choice is not just downrigger or outrigger. It is whether the rest of your setup supports the system.

With downriggers, release clips, weights, mounts, rod holders and line choice all matter. You want reliable clips that release cleanly, and enough rod backbone to handle the lure style and expected fish once the line comes free. Your boat layout matters too, because poor mounting position can make resets awkward and fights messy.

With outriggers, halyard quality, clips, rigging tension and pole length all affect how your spread fishes. Badly rigged outriggers are worse than no outriggers at all. Lures will not track where expected, and clearing a hooked fish becomes harder than it should be.

This is where buying from a specialist tackle shop helps. If you already know the exact components you need, great. If you are half-sure and trying to piece together a complete trolling setup, getting the right clips, leaders, rigging parts and supporting hardware in one place saves a lot of wasted time.

Can you use both?

Yes, and in some situations that is the best answer.

A lot of anglers think in terms of either-or, but a downrigger and outriggers can complement each other. You might run a wider surface spread from the outriggers while keeping one lure or bait deeper on the downrigger. That gives you coverage across both width and depth, which can be useful when fish are not locked into one feeding zone.

The catch is complexity. On a small crew, mixed systems can become a handful during a strike. If two rods go off at once, one from the rigger and one from the downrigger, everyone needs to know their job. So while both systems can work together, they work best when the crew, boat layout and rod plan are sorted before lines go in.

Which one should you buy first?

If you mostly troll offshore for pelagics and want to run multiple lures properly, buy outriggers first. They improve spread performance immediately and suit the way many Australian bluewater anglers fish.

If you are repeatedly marking fish deep and struggling to get offerings into the zone, buy a downrigger first. Depth control is hard to fake, and once you need it, nothing else quite replaces it.

If your fishing is mixed and your budget only stretches one way right now, be honest about the problem you are actually trying to solve. Better lure separation points to outriggers. Better depth presentation points to a downrigger. Gear works best when it answers a real need, not when it just looks the part in the catalogue.

At Reel 'N' Deal Tackle, that is usually the simplest way to sort the decision - start with the fish, then match the system. Get that right, and your trolling setup stops being a collection of parts and starts working as a proper spread.
