Let’s cut through the BS and establish the real difference between monofilament and fluorocarbon.
These types of fishing line are not the same, nor is one better than the other.
They are both unique, and a good angler uses their uniqueness to excel in different scenarios.
Difference Between Monofilament and Fluorocarbon
Monofilament and fluorocarbon look the same, right?
They are both somewhat transparent, with a slick texture and even a little shiny.
Given this, novice anglers fail to realize the difference between monofilament and fluorocarbon.
So, let me give you a quick breakdown then a more in-depth explanation.
[page_section template=’1′ position=’default’ padding_bottom=’on’ padding_top=’on’]
For those of you looking for a quick answer.
- more abrasion resistant
- sinks in the water
- nearly transparent
- UV resistant and zero water absorption
- stretches less than monofilament
- more costly
- suspends in water
- stretches more than fluorocarbon
- susceptible to water absorption and UV damage over time
- much cheaper than fluorocarbon
So this means…
Since both lines have different characteristics, they will perform differently, therefore having different applications.
Fluorocarbon is best suited for deepwater jigging, cranking or any kind of application that requires the lure to sink in the water column.
Fluorocarbon also does well when dealing with “spooky” fish. Because it’s transparent, it is difficult for fish to see underwater.
Monofilament is great for topwater lures. Fluoro would sink when you stop retrieving, potentially dragging the topwater down or getting hung up on the bottom.
Because monofilament stretches, it is also a good leader line to use. This removes shock from the fish strike, making tackle less likely to break.
Difference Between Monofilament and Fluorocarbon – A More Detailed Look
Only hardcore anglers thirsty for knowledge would keep reading! :)
Monofilament and fluorocarbon are both created using a manufacturing process called “extrusion”.
Extrusion is the process of taking the liquid form of a substance and pushing it through a tiny hole, in order to create a single filament, or mono-filament, of line.
[thrive_text_block color=”red” headline=””]This leads novice anglers to believe that fluorocarbon is the same as “monofilament” and therefore the same kind of fishing line, just more expensive and supposedly “superior”. [/thrive_text_block]
This is simply not true.
What they’re made of.
The major difference between monofilament and fluorocarbon is their unique molecular composition.
In short, they are simply not the same.
Monofilament has nitrogen and oxygen in its makeup, while fluorocarbon does not.
[thrive_text_block color=”purple” headline=”Fun fact”]”Monofilament” is really Nylon, the same material used to make toothbrushes and those pantyhose Hooter’s girls wear.[/thrive_text_block]
Anyways, fluorocarbon has fluorine, whereas monofilament doesn’t.
[thrive_text_block color=”orange” headline=””]Since they are both made from different materials, they inevitably have different characteristics.[/thrive_text_block]
Both fishing lines have different densities:
- Monofilament – 1.15 g/cm3
- Fluorocarbon – 1.78 g/cm3
And for comparison:
- Freshwater – 1 g/cm3
- Saltwater – 1.02 – 1.03 g/cm3
Fluorocarbon is denser than monofilament, making it more resistant to abrasion.
Monofilament is nearly the same density as water, making it neutral-buoyant.
This is the opposite of fluorocarbon, which is denser than both, allowing it to sink.
Fluorocarbon does not stretch as much as monofilament (though it does stretch a little), making it more sensitive.
Given it’s qualities, fluorocarbon is also UV resistant and doesn’t absorb water, increasing its lifespan.
Monofilament stretches more, making it more shock-resistant than fluorocarbon.
Monofilament and fluorocarbon have different refractive indexes, meaning one refracts light less than the other.
Fluorocarbon refracts less light than monofilament, increasing its invisibility.
Compare prices between the two next time you are at the tackle store. The difference will be obvious!
The reason why fluorocarbon is more expensive than monofilament is because the material and extrusion process is more costly.
How does this difference between monofilament and fluorocarbon apply to inshore anglers?
Every difference between monofilament and fluorocarbon is an advantage that we, as inshore anglers, should be exploiting.
[thrive_text_block color=”teal” headline=”Remember”]One fishing line is not “better” than the other. Wise anglers know how to use both to handle different scenarios.[/thrive_text_block]
This is not lost on bass anglers, as they fish bodies of water with a lot more pressure than we do.
They must make the best use of every tool in their toolbox or, in our case, a tackle box!
Monofilament’s Inshore Applications
Recall that monofilament is nearly the same density as water, being only slightly heavier.
This makes it “neutral-buoyant” meaning that it doesn’t really sink or float.
It just stays in one place, at that one depth.
This makes it an excellent candidate for topwater lures, especially those requiring pauses in the retrieve.
If you were to use fluorocarbon for topwater lures, you’d be awfully surprised when the topwater doesn’t perform correctly because it’s nose is being pulled down by the weight of the fishing line.
If I weren’t using braided line for popping corks, I’d definitely use monofilament!
Because monofilament stretches, this makes it an excellent shock leader, especially for braided line (which hardly stretches at all).
The sudden “shock” of the line going from limp to taut during a hard fish strike could cause it to fail, especially at the knot.
Have you ever seen someone bungee jump?
The rope used is designed to stretch, taking the shock out of the fall when the jumper runs out of slack.
Otherwise, the shock of suddenly running out of slack would seriously injure the jumper!
Monofilament makes a great “backer” on spools to reduce overall fishing costs.
Why spool 200 yards of PowerPro fishing line onto your reel when you can spool 75 yards of monofilament, join it to your braided line, then spool on the 65 yards of braided line you will actually use?
This also applies to fluorocarbon, especially since it’s more expensive!
Monofilament comes in different colors, making it even more useful!
Different colors help when untangling lines, but also for “line watching”.
This involves watching a slack line for movement to detect a bite.
A brighter colored line is easier to see and makes this technique easier to execute.
This is what Chas Champagne describes in his podcast.
Fluorocarbon’s Inshore Applications
Remember, fluorocarbon sinks, is nearly invisible underwater, and has more sensitivity.
“Deep” in the realm of inshore fishing can be anywhere from 10ft to 30ft, give or take.
Jigging in deeper water is radically different from jigging in shallow water.
An angler’s understanding of water geometry must operate at an expert level to catch fish.
This is where fluorocarbon comes into play.
Since it sinks, it can only help lures reach the bottom of the water (which is the goal in deepwater jigging).
Theoretically, this allows for less of a “bow” in the fishing line.
Combine this with fluorocarbon’s sensitivity to achieve improved hook sets.
Fish strike much softer when they are cold, like in the winter.
A faint bite is more easily detected with the sensitivity of fluorocarbon.
Also, one can use a lighter jighead, allowing for a slower, more uniform fall.
[thrive_text_block color=”note” headline=”Superior Presentation”]
From my experience, over the the winter of 2016-2017, an 1/8oz jighead paired with 12lb fluoro outperformed a 1/4oz jighead with braided line.
Despite casting at the same spot, using the same technique with similar rod/reel combos, the fluorocarbon and light jighead consistently got more bites.
You’d be surprised how many anglers throw deep-diving crankbaits inside inshore waters.
The deeper the water, the more challenging it is to get that crankbait down there.
If an angler were to use monofilament, he’d virtually guarantee that crankbait to never reach its target depth.
Spooky fish are fish that aren’t eating because they are easily scared by anything and everything.
One way to get them to strike is to use a fluorocarbon leader.
Recall the low refractive index of fluorocarbon, and remember that fish will be less likely to see the line and become “spooked”.
There is a big difference between monofilament and fluorocarbon, and one is not “better” than the other.
They are just different, and good inshore anglers know how to harness those differences.
Those who do enjoy more success than those who don’t.
