Intro To Seaguar Threadlock Hollow Core Braid

Available in tests from 50 to 200 LBS, Seaguar Threadlock takes braided fishing line to the highest limits. Abrasion resistance is at its highest with a 16-strand Polyethelyne weave. That same 16-strand feature along with its hollow core make splicing to fluorocarbon line a breeze. Finally and despite the listed line specs, anglers claim their spools hold up to 20% more line when using Seaguar Threadlock.

Main Features Of Seaguar Threadlock Braided Fishing Line

Tight 16-Strand PE Weave

While most braided lines use 4 or 8 strands in their weaves, Seaguar Threadlock goes with 16-strands. The strands consist of strong Polyethelyne fiber, just like you find in Sufix, KastKing, and other popular labels. Seaguar calls the Threadlock a high-density braid due to the tight proximity of each weave.

Hollow Core Braid

It’s common practice for many braided fishing lines to use a monofilament core. The weave forms around this center line which lends it some body and memory. When it comes to splicing and line to line connections, hollow core ties a stronger knot. Knots with hollow core line also don’t stick out as much, allowing them to pass more smoothly through line guides.

Extreme Abrasion Resistance

Because Seaguar Threadlock weaves an extremely tight 16-strand braid. it stands up to abrasion much longer than other lines. Rocks and structure will scuff up any braided line, but even normal use will cause it to fray in time. One thing Seaguar Threadlock offers is a much longer timeline of use than typical braids. A big feature that avid offshore anglers will appreciate.

Easy & Strong Wind-Up Splicing

Strong line connections mean everything when battling saltwater trophy fish which is why many anglers use a splice. Only hollow core line will work for splicing, as the fluoro or mono must fill the center of the braid. FISHTRACK has a great slide show that explains how to splice mono to braided line, the same as you would with fluoro. That tight 16-strand weave that Seaguar Threadlock uses makes splicing a cinch. It also increases the grip of the splice when it’s under pressure.

Super Smooth Due To A Rounder Weave

One characteristic of braided lines with smaller strand counts is a rougher feel. The rough diamond weave of KastKing SuperPower braid is a good example. Lines like the Sufix Performance braid will also fall short in comparison of smoothness against Seaguar Threadlock. Having 16-strands gives Threadlock an advantage because it naturally forms a rounded braid.

A Focus On Strength & Impact Resistance

When the beasts of the ocean first strike, they do so with tremendous amounts of speed and power. The blast of spray that occurs when Marlin or Wahoo hit a topwater lure is explosive. That same impact goes directly into your braid, which must withstand the enormous stress of those first few milliseconds. Seaguar Threadlock absorbs that impact before your drag engages.

Pros & Cons Of Seaguar Threadlock Braided Line

Pros




Whether you splice Seaguar Threadlock or connect it with a knot, the hollow core braid adds strength. Having extra abrasion resistance and smoothness go along with this 16-strand braided line.

Extreme impact absorption is another big bonus, especially when those trophy fish strike. Finally. adding up to another 20% of distance on the reel spool in comparison to other 16-strand lines is never a bad thing.

Cons

Seaguar Threadlock doesn’t list the old colors which means Blue and White are the only choices. Spools of this hi-density braided fishing line also don’t come cheap. There are plenty of situations where Sufix 832 Advanced Superline or Power Pro Spectra will work just as well.

Best Situations / Uses

The biggest feature of Seaguar Threadlock is the ease and strength it lends to splicing. Splicing line together results in a near flawless transition, making it flow through line guides as if all one piece. The braid cinches down with a vice-like grip on the spliced line when fish pull.

Besides having threads that lock, the braid has all around desirable qualities. If it fits within your budget, who wouldn’t want more strands and a higher impact rating? Even though Threadlock costs more, it lasts longer than other braided lines. Its abrasion resistant formation adds durability and so raises its value.
