Tuna Fishing Line

Izorline XXX Super Copolymer Smoke Fishing Line— 1/4lb Spools

When you need a line that disappears in the water column and holds up under pressure, Izorline XXX Super Copolymer Smoke delivers. Engineered with next-generation space-age additives, this monofilament packs exceptional strength into a small diameter — giving you more line on the spool and a stealthy edge over wary fish.

The smoke color is purpose-built for low visibility, making it a go-to for targeting sharp-eyed species like yellowtail, white seabass, and tuna. Whether you're fishing the surf, jigging offshore, or chasing trout in freshwater, XXX Copolymer performs where it counts.

Key Features

• "Xtra" Limp — Soft, supple, and easy to tie reliable knots
• "Xtra" Strong — Izorline's strongest monofilament ever produced
• "Xtra" Tough — Superior abrasion resistance for rocky structure and heavy cover
• Low Memory — Minimal coil and line twist for longer, more accurate casts
• Small Diameter — More line capacity on your reel without sacrificing strength
• Smoke Color — Near-invisible underwater for a stealthy presentation

Specifications

Note: Spools are sold by weight, not line length. Lighter test lines have more yardage per spool due to smaller diameter.

The Leader That Disappears Underwater

Seaguar Gold Label Fluorocarbon Leader is engineered for situations where fish are leader-shy and every advantage matters. Built thinner and less visible underwater than any other fluorocarbon leader on the market, Gold Label gives you more natural presentations, better bait action, and higher catch rates on the fish that refuse everything else. From ultra-light trout rigs to heavy big game setups, it's available in 2lb through 150lb to cover every application.

Double-Structure Fluorocarbon — Built Different From the Inside Out

Seaguar's exclusive DSF (Double Structure Fluoro) process combines two custom fluorocarbon resins into a single leader with a smaller diameter core and a tougher outer layer. The result is a leader that's 18% thinner than standard fluorocarbon, 17% stronger in both knot and tensile strength, and significantly softer — so it cinches cleanly into fail-safe knots without the stiffness that causes slippage or breakage under pressure.

When Standard Fluorocarbon Costs You Fish

On pressured fisheries — clear water, finicky yellowtail, spooky white seabass, wary trout — leader visibility is often the difference between a bite and a refusal. Thicker, stiffer leaders kill bait action and flash in the water column. Gold Label's ultra-thin diameter and near-zero memory let your bait move freely and naturally, and its refractive index matches water so closely it effectively vanishes at depth.

Why Gold Label Outperforms Standard Fluorocarbon

• 18% thinner diameter — less visible, better bait action
• 17% better knot and tensile strength despite smaller diameter
• Lowest line memory of any fluorocarbon leader — easier to manage, fewer tangles
• Extremely soft and supple — cinches easily for clean, reliable knots
• 100% fluorocarbon — near-zero stretch, abrasion resistant, UV stable
• Level Wind Technology for consistent, even spooling
• 25-yard spool — right-sized for leader material use

The Right Pick If...

• You fish clear water where leader visibility costs you bites
• You need a leader that ties clean knots without stiffness or memory issues
• You're targeting finicky species that refuse heavier or more visible leaders
• You want one premium leader that covers light inshore to heavy offshore applications
• You trust Seaguar's fluorocarbon expertise — they invented it

Best Fishing Techniques

Ideal for live bait fishing, drop-shotting, finesse jigging, Carolina rigs, fly fishing tippet leaders, kite fishing, and any technique where leader invisibility and natural bait presentation are critical. Heavier sizes (50–150lb) are built for offshore big game, shark, and heavy inshore applications.

Best Conditions

Clear water, high-pressure fisheries, bright sunny days with high visibility, and any situation where fish are leader-shy or have been heavily targeted. Also excels in low-light conditions where the refractive index advantage keeps the leader invisible at depth.

Best For

• Yellowtail and white seabass on the California coast
• Tuna — both light tackle and heavy big game setups
• Trout and bass in clear freshwater lakes and rivers
• Calico bass and inshore saltwater species
• Surf fishing with finesse presentations
• Offshore billfish, shark, and heavy leader applications (80–150lb)

Key Features

• 100% fluorocarbon — abrasion resistant, UV stable, near-zero stretch
• Level Wind Technology
• Spool length: 25 yards
• Available: 2lb through 150lb
• Vendor: Seaguar

Models & Specs

Tackle Express Tips

• Match the test to your mainline: A good rule of thumb is to run Gold Label at 2–3x your mainline test for most inshore and freshwater applications — the thinner diameter keeps it invisible while still providing the abrasion resistance you need near structure.
• Use a loop-to-loop or FG knot: Gold Label's low memory and soft construction make it ideal for the FG knot when connecting to braid — the supple material cinches tight without the stiffness that causes slippage in stiffer fluorocarbons.
• Store out of direct sunlight: Even though fluorocarbon is UV-stable, prolonged direct sun exposure on the spool can degrade the resin over time. Keep spools in a tackle bag or drawer between trips to maximize shelf life.

FAQ

What makes Gold Label different from standard Seaguar fluorocarbon?
Gold Label uses Seaguar's exclusive DSF (Double Structure Fluoro) process — two custom fluorocarbon resins combined into one leader. This gives it an 18% thinner diameter and 17% better strength than standard fluorocarbon at the same test rating, plus significantly lower memory for easier handling.

Which test should I choose for yellowtail and white seabass?
Most Southern California anglers run 20–40lb Gold Label for yellowtail depending on conditions, and 25–40lb for white seabass. In cleaner, clearer water, drop down a size — the thinner diameter will get you more bites on pressured fish.

Can I use Gold Label for freshwater applications?
Absolutely. The lighter tests (2–12lb) are excellent for trout, bass, and panfish in clear lakes and rivers where leader visibility is a factor. The same invisibility advantage that works offshore works just as well in clear freshwater.

The Line SoCal Anglers Trust

Izorline XXX has earned its reputation on the water — not in a marketing brochure. Veteran long-range and local sportboat anglers have relied on it for decades because it delivers where it counts: small diameter for more line on the spool, exceptional knot strength, and a smoke color that disappears in the water column. If you're fishing yellowtail, tuna, or white seabass, this is the line that won't let you down when the fish of a lifetime is on the other end.

What Makes XXX Different

Izorline engineered the XXX formula with space-age copolymer additives that push monofilament performance beyond what standard mono can deliver. The result is a line that's simultaneously limp enough to cast effortlessly, strong enough to handle hard-running pelagics, and tough enough to survive the rocks and structure where big fish live.

• Xtra Limp — soft, easy to tie, minimal coil memory off the spool
• Xtra Strong — Izorline's strongest mono formula, with high knot and tensile strength
• Xtra Tough — excellent abrasion resistance for rocky structure and kelp
• Smoke color — low visibility in the water column, a proven edge on pressured fish
• Small diameter — more line per spool, better bait presentation

When Line Visibility Costs You Fish

Clear water and pressured fish are unforgiving. Heavy, stiff, or high-visibility line kills bait action and spooks wary fish — especially white seabass and finicky yellowtail. The XXX's smoke color and ultra-limp formula let your bait swim naturally and your line stay out of the picture. It's the difference between getting bit and watching the fish swim away.

The Right Choice If…

• You're fishing live bait on local or long-range sportboats
• You want a mono that casts smoothly and ties clean knots without stiffness
• You're targeting clear-water species like white seabass, yellowtail, or tuna
• You need maximum yardage on your reel without stepping up in diameter
• You've been burned by cheap mono that breaks at the knot or loses strength after a few trips

At Home In These Situations

• Live bait fishing for yellowtail, tuna, and white seabass
• Slow-trolling and drift fishing on local and long-range trips
• Jigging and iron fishing as a main or backing line
• Freshwater applications where low-vis and low-memory matter

Best Conditions

• Clear saltwater — inshore, nearshore, and offshore
• Long-range and overnight sportboat trips
• Kelp and structure fishing where abrasion resistance is critical
• Any situation where fish are line-shy or water clarity is high

Best For

• Yellowtail, bluefin tuna, yellowfin tuna, and albacore
• White seabass and calico bass on live bait
• Freshwater bass, trout, and general light-tackle applications
• Anglers who want a premium copolymer without the premium price tag

Key Features

• Formula: Super Copolymer with space-age additives

Models & Specs

Tackle Express Tips

• Spool under light tension with water or a damp cloth to reduce memory and ensure even lay on the reel — especially important on larger capacity reels.
• The smoke color is most effective in clear, blue water. If you're fishing green or murky water, the visibility advantage is less critical — but the strength and limpness still make it a top pick.
• For long-range trips, the 1lb spool gives you enough line to fill most conventional reels and have backup. Buy two if you're spooling a large-capacity reel like a Talica 20 or 25.

FAQ

Is Izorline XXX a monofilament or fluorocarbon?
It's a super copolymer — a step above standard monofilament in strength and limpness, but not fluorocarbon. Many anglers use it as their main line with a fluorocarbon leader for the best of both worlds.

What reel sizes does the 1lb spool fill?
Capacity varies by test strength. The 20lb/2,670yd spool will fill most mid-size conventional reels. Refer to your reel's line capacity specs and the yardage table above to match the right test to your setup.

Can I use this line for freshwater fishing?
Yes — the low memory, small diameter, and smoke color make it an excellent choice for freshwater bass, trout, and other species where line visibility and castability matter.

Izorline Fluoro Carbon Wind-On Top Shots are the fastest, Stronest, and easiest way to connect Spectre/Braid to Fluoro. There is a small learning curve to fishing Wind-On Top Shots, the Izorline Fluoro Carbon Wind-On Top Shots have a spectra loop on the end so you're going to need to serve a loop in your hollow core spectra to make the loop to loop connection and if you do not have hollow core then, you'd have to tie a Bimini twist loop in the end of your solid spectra to make the right connection.

A Wind-On Top Shot is one of the most in-line connections from braid to Fluoro making it virtually silent and smooth going through the guides on the rod. Also a Loop to Loop connection is the strongest connection for spectra to Fluoro.
