Underwater Visibility Test of Braided Fishing Lines

We’ve compared different color monofilament and flourocarbon lines but today we wanted to compare braided lines. We put white, blue, yellow, red, orange, and green 40 lb braided lines on our testing rig and went underwater. We performed this test in both clear ocean water and in dark pond water. We also tested what color of braid line was the easiest to see above water in case you are looking for a good high vis line.

it doesnt matter if we can see it, fish have different eyes and diff vision

kizz jd says:

He sounds high af lol

Mr T says:

Unless you can ask a fish this is a meaningless waste of time. All scientific evidence to date suggests that most fish see into the ultraviolet range, how much of other wavelengths we do not know. Visibility probably has more to do with reflectivity and flouresence. For many decades Green string was all you could get and it caught fish, it still catches fish.

2centavos says:

Nice vid- you are a good presenter. If you ever get the urge to do another one could you compare the various types/colours of flouro? That seems to be the big debate amongst experienced anglers. Thank you.

KE Chock says:

It has very little to do with what colors a human sees at/ near the surface. Depending on wavelength, light waves are increasingly absorbed and scattered with depth. Red, orange, yellow are nearly gone by 10 ft down. Violet, green, gray, and blue go much deeper. But fish see colors differently, and scientists still do not know exactly what they see (but evidence suggests more sensitivity to UV spectrum). Buying line based upon what YOU see in unfiltered white light makes little sense, especially if you’re fishing deep. And you are not a fish.

MrNorthstar50 says:

Good video,I think the real question is which color do the fisherman bite on at the store.

Dr MitoFit says:

Thanks! Ponds are dark or stained from tannins (like tea) from decaying leaves. I use 15 or 20 lb dull dark green braid with no leader and catch more bass than anyone at my favorite lake. It seems to camouflage really well in the tea colored water, algae, and weeds. Plus I have a theory that thin braid cutting through the water is felt and heard less and thicker mono/fluoro in the same lb test by a fishes lateral line. Fish use their lateral lines and hearing since sound travels better in water than in air. Thin line is always better, so braid is all I use now. It is so strong that I never have fish break off and I can free lures with thin wire hooks by pulling (line wrapped 6 times around a dowel to prevent packing the spool). With jigs I can tell exactly what the bottom is made of and can detect subtle bites due to the low stretch and high sensitivity of braid.

Nice tips friend, your new subscriber

john foy says:

When a fish is focused on eatin a plug or bait believe me he aint payin attn to what color line you have on.all bullshit.if hes not in the mood to eat or hesitant or chasin out of curiosity maybe,but if it makes the decision nothin will change its mind.

Scott Mehlhaff says:

nice one thanks.

Jonathan Rojas says:

I think the real questions is what colors can each type of fish see.

Danny Velasquez says:

You know I have no idea what fish see and I have no idea if they see all colors, but this has to be one of the best, smartest and affordable videos I have ever seen. Well made video RH! I really appreciate your efforts. Thank you.

captzumafishing772 says:

#1. We don’t know what a fish sees.
#2.the fish is focused on the bait..hopefully tied onto flourocarbon which is invisible

Justin Miler says:

I love how you did the different water tests because i fish fresh and salt water

adam kellett says:

Why do People worry about fish seeing the line. When there a big hook hanging off the lure. They have no trouble biting that .lol

Preferred Stock says:

A geeked out Stevie-O

Foothills Crafted says:

Great idea and presentation. Thumbs up.

Kage Shi says:

I use neon yellow with a drk greencamo leader or steel leader in most of my trolling stuffs as I do it at night with UV lights to help attract bugs to the waterline and can keep eyes on my kit without needing bright lights to kill my vision under moon/star light. In the daytime I use the drk green/camo and a steel leader to make swapping lures faster as I at best only carry 3 rods and one is just for crappy with light line and fly jigs.

Reel Fishing says:

What about black ?

I was in a saltwater canal , it seem dark , but the white fireline stood out A LOT , and I notice the fish really didn’t bite the bait either , but when night time I switch over to a black line and they strike the bait , because the line was way harder to see at night and in the dark water

MrKveite1 says:

Dont mather since smart fishermen use a mono/fluro LEADER.

Reel500 says:

Thank you! I am just about to buy a 1500 meters braided line then I your video helps a lot.

Cluck Cluck Boom says:

Totally of topic, but if you own a boat in the USA, you give yourself the title of capt? Really?

Ate Up Angling says:

Great video

Andy T says:

Neat little text but it was sloppy

Michael McKinsey says:

Trolling isn’t fishing

breathe and squeeze says:

this was well done, but, this is simply how the lines look to the human eye. fish don’t see the same way we do. so really, this video is for fisherman to buy lines that THEY don’t see as well in the water. fish see UV. you would be “shocked” at how some lines glow in uv light. my jaw dropped. a line I thought was extremely invisible(it was to my vision), glows like it is lit right up when hit with a uv light. and I assumed that would have to be very bad. BUT, I looked at my rod that I had just been using on a weekend trip, and that was the line I was using for the leader on it. and I caught loads of fish and one of my biggest in that lake. so now, I started to consider that maybe THAT is what helped ATTRACT the fish, was the glowing line. it may have brought them in, then they bit the lure trailing on it. it definitely didn’t spook or scare them, that’s for sure. the biggest thing I have learned about fishing, is that we usually don’t know all that much about what the darn fish are doing. one day a certain lure is a fish magnet, they won’t leave it alone. the very next day, same light conditions etc, and that lure doesn’t even get a look. we are always told that we need to be careful that the fish can’t see our line, well, my line glows like a beacon, and the fish seem to attract to it.

pro welder says:

It’s called fishing for a reason

Alan Kanowitz says:

Great video. Thanks for the info.

blue widow says:

Cool experiment but just cause we can’t see it don’t mean a fish can’t see it also the green in ocean water might be visible to use but to a fish it might be invisible we will never know

Jason Le says:

useless, the fish bite all, they dont care the wires

The old coins of India says:

hey bro YOU presented a quality video me watching in INDIA & I have a similar video but with no technology being used…KEEP PRODUCING VIDEOS AS YOU GO ON…GREAT JOB.

joapps says:

Do u fish for humans? Are u sure fish sees the SAME as humans? Are u sure all species of fish see exactly the same?

Dale Hammond says:

I’ve been an avid fisherman since the 50’s and am convinced that line visibility matters most when the fish aren’t feeding and/or the natural food source is high. I think fish see all lines but the less visible lines register a lower caution signal in the fish’s brain. The more visible the line, the bigger the lure and/or bait can seem to the fish. Fish are able to determine the size of the potential prey. A fish that isn’t very hungry could back-off from a bait simply because the line confuses him a bit as to the actual size of the prey. Since eating isn’t a matter of life or death, he backs off. A lure or bait with lots of action (that’s easier to evaluate as to size) is more likely to provoke and spontaneous strike than a confusing lure or bait. Just my thoughts. Great video.

Rookie Budget Fishing says:

This is interesting. Only if there was a way to mimic the biological make of a fishes eye an as they see it.

Yunior De los Santos says:

The real question I have is: Do the fish really care once they see the line?

Big daddy says:

Man I see everything

Jmichael Isbell says:

Jonathan (below ) has the key question. Your video is good, and interesting, BUT, it seems predicated on the assumption that the visual acuity of the fish, is the same as the human. I for one, have no idea if they are the same, or totally different. But if you don’t know, then the results can’t mean much.
