Been looking at these 2 knots which one would you say is best. Just started into jigging and have had a few failures. Have now mastered the pr knot hopefully will find out Sunday how good they are when I came across this FG knot. Any one who has used both and can add some insight to these would be good,

They both work pretty well, the key with the fg knot is to really put some tension on the first half hitch that you do.
Fg casts better but i think for reliability the PR is hard to beat.

Well lets say they look good
If I manage to hook up any kings on sunday it will test the strength of me knot. They are not to hard to do with the Bobbin and Mark (Ginga) made it look so easy when I was out with him.

Cheer's Mark I can see from the video on U-tube that they have to pull hard and wet the knots before they tighten them up so friction does not damage the line.

FG is very good and reliable when done properly.  But I look at the many many tight wraps on a PR and compare it to just 12 cross wraps of the FG.  My teeth have never been the same either!  Cheaper and probably stronger and more reliable with PR.

Seems most like the PR knot being better, but the FG is a smaller knot which may have some advantages as well.
Will have to see how my PR knots hold up but will have to learn the FG as a back up and maybe for a casting knot with it being smaller.
Thanks for comments on the knots.

At the Japanese Jig & Pop show, they were holding demos in tying PR knot, I have seen them doing it for a few years now.

I've learnt FG from Konishi and tied it many times but you have to pull the leader and braid in 4 opposite directions so that the braid bites into the leader.  You have to use your teeth to hold the leader tag.  After paying my dentist twice to fix my teeth over this, I just tie the PR, much cheaper dentist bills now.  No reason why you can't tie a short PR if lenght is a concern.

Thanks Christ sounds like stick to the PR knot and just have the FG as back up because if Like Ginga says i forget me bobbin.

Does anyone use the reverse albright. They are very popular in the states and recommended by tackle stores such as Charkbait.


Posted By: ChrisW
Date Posted: 24 Jul 2010 at 8:23pm
the Albright knot is quite large and could easily take out a rod guide.  PR and other Japanese knots are far more compact.
 
Charkbait is located in California and their style of fishing, tackle etc is steeped in tradition.  The West Coast anglers are quite resistant to change, they are very slow to recognise the Japanese style of jigging and the advanced tackle involved.  The East Coast is quite the opposite and MJ is very popular and the tackle selection is very advanced for just a few years.

no teeth involved, just learnt the FG today, is based on how you secure a fibre rope with chain (a chain stopper), just very very many more turns, the PR Knot is based around a rolling hitch. I have trusted both with my life. If push came to shove I would say the PR knot is probably the better, but at close to a hundy for a bobbin, it can GFd.
No teeth method: slap your rod in a suitably placed rod holder, thread the braid up the eyes as per normal, and secure the end some where convenient, set the drag on your reel appropriately - to do what it does best - apply the desired amount of tension, the bend in the rod should act as a spring to help here.
 I"m no expert, but about 1 - 1.5 kg seemed to work ok. any more and the plaits started trying to capsize when I tied it. 
On lighter gear, soft bait and stray line to 15 kg, an albright knot is hard to beat, depends I suppose on the size of the trace relative to the main line.
The bloke who said learn to tie the knots you like to use, well, is on the right track.  I survived for many years knowing only four knots - the improved clinch, blood knot, a dropper loop (for making up, you guessed it, dropper rigs) and a figure eight (which can be rethreaded a la indoor rock climbing to secure jig heads etc). If anyone has tested a figure eight against the alternatives i'd love to know the results. My repertoire has grown considerably since, and I now use a uni knot in preference to an improved clinch - most of the time, otherwise KISS

If i could use only one knot it would be the UNI......learn to tie it with your eyes closed.......The PR is quick and easy too.........I used to use bimini twist with wind on leaders but it gets expensive that way....Cant be bothered with the FG.

x2 for this technique , basically braid out of rod tip  , secure to reel handle with a loop. Let enough out so it can be formed into a triangle (like a bow and arrow). Simply keep tension on as you weave leader around alternate legs of braid (keeping tension) , half hitches as required with finishing hitch. So easy , actually best to do on boat in rod holder as sonofafisherman has stated , I used for in lighter lines for softbait and slow jigging also. There was a youtube clip showing this.

I think the question many of us still have (tried MJ maybe twice but interested anyway) is if the FG knot is a good option for mechanical jigging or does the PR knot still rule?

I used to do PR for everything inc. casting but now I have the FG down it's the only connection knot I use. Never had one fail even up the three kings!
Much better for casting too.

I use the FG.. rod in holder as extra hand method.. braid to leader, mono/ fluro.
Tied right and pulled up its near on 100%  and with a little practice a 24 turn done in around 30/40 seconds

Bimmini, another near 100% knot....again rod in holder as extra hand 30 twist up, 1/2 hitch each side an 2 to 3 to finish.
Again quick strong and around 30 to 40 seconds depending on loop size.
Use this for clips , swivels at the end of braid main line that are then cats pawed on.
Also use to join braid.....main braid on the  reel spool, adding more from fresh brought spool....biminini in both ends then cats paw the new spool end thru the loops as would doing clips  above.

FG biminis IF pull up the finishing knots tight as each is tied, pass thu rod eyes very nice

Thanks Pete, I use the FG knot too and it's great for my type of fishing, now that it's been around awhile I was wondering how it went on big fish.

With IGFA now talking of allowing braid with a 5m section of mono for records I wonder which knots the game fishers will use. Keen to hear who is still using the PR knot.

"I was wondering how it went on big fish."


I have never tied a PR and don' t even have a  bobbin. I have learned the FG and can tied it in a short time on the boat with the rod on my lab.
Fishing from a small boat so i also use my popper rods for trolling. Caught 70lb + GT's and use the same knot to catch a marlin two hours later, i think the FG knot can stand up to big fish.

A couple of weeks ago we were stuck off the Great Barrier Reef waiting for the wind to wane and spent 2 days testing the PR vs FG. PR was stronger in every head to head test but doesn't cast as well,especially if you tie it long. We decided that in a small boat the PR is tough to tie but if you have a spare spool or two then it is stronger and may be the best. Having said that we had no failures on GT or doggies because the knot failed.

Interesting you say the PR doesnt cast as well.........I tie a 2 inch PR ........There are many variables in play to state the PR doesnt cast as well.......eg rod length.......leader weight and length ....length of Knot and the resistance it meets going through the top guides(especially if wound onto the spool) ...........a 2 inch PR casts beautifully ......I use a 4 metre leader which is extravagant to many but i get no resistance going through the guides..........If you are doing things right......you will hear no noise when you cast........its helps if you have a big top guide as well.........the key?..........have a long hang down from the tip,of rod to your lure.....within reason ..If its really long you will screw up the cast............the advantages are 
1.....better leverage to obtain more power from a bigger arc...therefore a longer cast....so relative to rod length.
2.....The knot will go through the guides and you wont hear a thing(providing leader is wound onto spool).......therefore no catching on the top guide with your FG or PR knot which can have disastrous consequences at worst.
          Too many people cast with a short backdrop ...when you do that.....your rod will not be at a friendly angle to allow easy passage of your knot on the cast.....a metre and a half drop down.....should be about right with no noise!.......then you have it right...Try it !...The short PR with UV knot sense applied.....does it for me....you can cast all day and the knot is protected against wear by the uv knot sense.Wink

I should rephrase my comments. The knots both cast well if tied similar lengths. Short PR about 1.5cm just the same as the FG. The PR does tend to unravel during a day of casting at the end attached to the leader, we didn't test the breaking limits compared to the FG once had been cast, maybe that's the test that needs to be done!

laidbackdood great post and would tend to agree.

PR knot preferred for bigger fish, Kings to marlin)
Albright - when out on boat with lighter tackle/snapper (faster easier etc)
Uni know for pretty much everything else (braid to spool, leader to lure)

I have been using much longer PR's, I shall try shorter.

Paulus from Oz is a world expert on braids and testing, check out his website for all test results of nearly every single braid that has been made.
His tests on the PR vs FG knot have the PR a clear winner at 85-90%, FG comes in around the 80% mark so both GREAT knots. Not many anglers would ever fish their line at 60% of ABS let alone 80% so no real need to worry which one you use.
Normally PR = jigging
FG = stickbaiting, (casting) as it is a little smaller in profile and shorter.

The GT knot is another one to consider. A bit bulkier, but can't unravel. Is as strong as the Bimini you use to tie it.

when you tie the short PR for casting.......dont finish with that Flemish Knot(its something like that hahah.....yuk.......flem lol) ....you know the one where you wrap it back down ..........You just do the last two half hitches like your life depended on it........then trim(Accident prone on here gave me that tip)......I always put uv knot sense around all those half hitches to seal them off.....put a little knot sense between thumb and forefinger and rub it along the Fg look a like bit.......put it in the sun to dry.....uv knot sense is like an epoxy glue that can flex.......your knot will not come undone ....its protects it every cast and if you cast like i said......there will be minimum friction put on the knot through your session anyway..Wink

To be honest i have never caught any kingfish on mine. It spend the last few years casting poppers at GT's. I think it got enough grunt to stop any GT but a stiffer rod might be better in very shallow water for big GT's.  I still prefer the lalandi paired up with a 10 000 Stella PG.
It's light enough for casting all day and best is it never hurts your back when fighting big fish.
If all is going well i will be chasing Kings in December when i am back.

One issue I have found with long PR knots is they obviously look like bait fish in the water when jigging. The 'couta hit them and it's all gone. Whichever knot you use for the  connection (especially for jigging) keep them as small as possible so less attractive to 'couta or other toothy critters Wink

The longer PR knots tend to leave a Bubble trail as well........I used a bimini mainline with a wind on leader for a long time and never had trouble with couda hitting the join..........
Maybe covering the PR knot with knot sense might help as well......I just put some in my fingers and rub up and down the knot between my fingers (its soaks in)and the let it dry in the sun.

Somewhat off topic for the heavy jig guys, but I now use the FG knot for my softbaiting- 20lb Snapper on 10lb braid/ 16 lb leader.
Handy if you snag as it tends to break at the jig head, not the knot......

Try using a PR knot ....put some UV knot sense between thumb and forefinger and rub along the whole knot and the half hitches.finishing knot............then rotate immediately........like synit would do with a rod while epoxy is drying............then see if you lose your knot to couda..........I have a theory and if people want to poo poo it....go ahead......i dont give a fooook ..............the PR knot coils form like a hang mans noose........eg nnnnnnn           those ridges in the line form a ripple effect...or the bubble trail as it travels through the water........the longer the coils the more it does it........
               well.......anyone want an argument?.....by using the UV Knot sense.......those ridges become filled in and the knot becomes one smooth --------- line on each side....so no bubble trail.............someone trial it...................There were never any issues like that with a Bimini twist and a wind on leader......so there has to be something happening within the PR strands itself to attract the couda........No couda ever hit the bimini/wind on leader join or all that hollow cord they put on the beginning of the wind on.

GI Joe started to venture to where the bubbles were coming from

I omit the bubbles right at the beginning when I first tie the knot - by keeping the wraps tight LOL

Imagine a plane wing. thats how the air bubbles form effectively, they dont need to be there from the start. 

Effectively it's Cavitation...

So PR knots emit air under water but jigs don't. Weird!

Sure. But where does the air come from?

Cavitation is caused from a pressure differential at the propeller, ie the pressure around the propeller decreases resulting in vaporisation of liquid. Your PR knot will most definitely not do that.

Very technical answer there starnsy.......
I have a theory and its pure speculation.......not based on facts......but hey if anyone can disprove it....go for it......
Look at the pic below.......the knot on the left represents a PR knot under a microscope(just the PR coils but would have the half hitches as well).........the one on the right represents a PR knot(coils) covered with UV Knot sense......
I believe its the ridges of the coils of the PR knot itself......that cause a trail as its going through the water.......when covered with UV Knot sense......It becomes a more streamlined knot.......more like a torpedo.........when the knot is longer it exasperates the trail.....
Any smart person who can prove or disprove my theory?

I always tie an FG knot.
I don't need any gear and it works well for my small brain.
I can throw the rod in the holder in adverse conditons and get a good knot fairly fast.
The thing I like best though is the AG chain for the terminal end.
Has abraision resistance in terms of rocks and sharp teeth and is a strong strong knot that is so easy to tie.
In terms of bubbles and Couta I tend to think if they are around your toast anyway just move on or spend money depending on your mood.
I just had an epic trip with big snaps on softies, some nice crays and a session on kings around 25kgs.
Sometimes gear breaks no matter what you do.
I lost a big fish under the boat because the loop at the assist hook let go, poor manufacture I guess.....
I was going to release it anyway I just wanted my jig back.

See the logic in that.. BUT lets consider the volume of air trapped...the result would be microscopic  and for a very short period, and not enough to effect anything.. the bubbles so tiny.
 And if the issue was cavitation, to form the friction has to be enough to boil the water to form a vapor trail... as with a prop.
And if apply the prop case to that, there is enough heat to melt the molecular metal  on the surface of the prop, eventually pitting it....so what would that heat do to the knot?  or the line materials?

 IF there where bubbles they would be so little so damn microscopic small for a ve short period of time.
 Issue is a non issue I recon.

 And if still worried use a FG...l

Steps  requiring water boiling to  produce cavitation is a falicy. Fsh are able to generate enough speed to develop bubbles, again its about pressure differentials and the microscopic bubbles that exist in water.

From wikipedia 
"Just as cavitation bubbles form on a fast-spinning boat propeller, they may also form on the tails and fins of aquatic animals. The effects of cavitation are especially important near the surface of the ocean, where the ambient water pressure is relatively low and cavitation is more likely to occur"

Inertial cavitation was first studied by  https://en.wikipedia.org/wiki/Lord_Rayleigh" rel="nofollow - Lord Rayleigh  in the late 19th century, when he considered the collapse of a spherical void within a liquid. https://en.wikipedia.org/wiki/Cavitation#cite_note-Rayleigh1917-1" rel="nofollow - [1]  When a volume of liquid is subjected to a sufficiently low  https://en.wikipedia.org/wiki/Pressure" rel="nofollow - pressure , it may rupture and form a cavity.


The pressure differential is the key.

Here is a great example

Getting a bit technical now, but 'boiling' is simply water turning from a liquid into a gas - water vapour. That's what the bubbles are in your kettle - not air. Increase the pressure - in a pressure cooker for example - and the water won't boil until the temperature is much higher, so your food will cook more quickly. Lower the pressure, and it will 'boil' at a lower temperature - about 70C on top of Mount Everest. 

Cavitation is when the pressure momentarily drops low enough for the water to briefly vapourise, often in a very tiny area, before the surrounding pressure collapses the bubble. The impact of the collapsing bubbles can be pretty severe and can cause mechanical damage to something like a propellor - sometimes called cavitation corrosion.

I wasn't aware a fish could cause cavitation from it's fins, but if so, a bulky knot probably could too. I imagine it would only occur fairly near the surface - same as propellor cavitation. At any depth the increase in water pressure would quickly raise the boiling point too high.

A separate issue is a knot, swivel, or game lure getting a gulp of air on the surface, and emitting an underwater bubble trail - probably more an issue for topwater lures than deeper water jigging. 

Back to the thread though - FG knot for me every time, from 4kg to 37kg. No tools, no broken teeth, takes maybe a minute to tie at home or at sea, runs through the guides without catching, and never fails, although I did have a few of the finishing half-hitches come undone until I started using a Rizzuto finish. Knot Sense would probably sort that issue too.

REF Couda.....I wonder if a diver has actually witnessed this so called bubble trail ?..........is it an issue on the drop when line speed is at its highest or during the jigging retrieve?
people......when has this happened to you most often?........while jigging or the drop?........
The bulky part on the line where knot meets mono.....might even look like a slim fish to a couda.......who knows......but there is a bloody big fish further down hahaha.....It needs to be witnessed and that aint easy........but without pure facts......I will stick to a shorter PR and coat it with UV knot sense..........the test would be if people around you are getting their knots hit by couda.........send one down with UV Knot sense on it and see if you are immune !LOL............then let us all know ...so we can save our jigs and their impact on the environmentWink

With my diagram above......the knot on the left.......I will draw another analogy.......
when swimming freestyle and you need to take a breath......if you turn your head back.....there is always a pocket of air there because your head creates a bit of a break........there is no need to lift your head out of the water because that pocket is always there.........i think those ridges act a bit like that.......the knot is not steamlined...smooth like a torpedo for less resistance.......the ridges create some resistance and the pockets are always there..........only way would be to test one long pr against a long PR coated with knot sense(smooth as) and watch.

  Yep Basic high school physics.... loooong time back  what was it ????  ( t1x p1)/ V1=(t2xp2)/V2 basic formula.. Newton Kelvin Boyle Pascal law cant rem which one it was now....Boyle?

but 'boiling' is simply water turning from a liquid into a gas - water vapour. ......Cavitation is when the pressure momentarily drops low enough for the water to briefly vapourise,         The impact of the collapsing bubbles can be pretty severe and can cause mechanical damage to something like a propeller - sometimes called cavitation corrosion.

It's actually real simple. No need for a scientific explanation here starship enterprise.

Dive down 20m. Wave your arm around. No bubbles. Kick your fins. Hmmm no bubbles. Get someone to drop a jig and crank it up. No bubbles

The snakes/bubble theory was spouted about a decade ago by someone on this very forum who really didn't think about what they were saying. Now there are still people believing it, without thinking for them selves. My neighbour still thinks the earth is flat. It's quite entertaining listening to his explanations and answers to my questions. Perhaps one to many St Pedro's special teas. 

My surfboard fins form cavitation and a mean bubble off the trailing edge. Especially when not sanded blunt. They are near the surface. Air is near the surface. 

From Dr Titahi's post "The effects of cavitation are especially important near the surface of the ocean, where the ambient water pressure is relatively low and cavitation is more likely to occur""

And Mike, up there for thinking, down there for dancing +) Get out there guys. Dose of sunshine and saltwater needed here. 

Oh and Smudge, looked up the definition of trawling troll. Think you may need some reflection on time on here vs time on the brine. Gotta love what you do I guess. Lter

I think for all of us, you should test this swimming theory out under water.

No, it isn't. Your post was though.

Some people actually want to learn, some even want to understand, and some can't do either, so mock both.

Correct, and none would be expected. Your point is ?

The snakes/bubble theory was spouted about a decade ago by someone on this very forum who really didn't think about what they were saying. 

Impressive memory. You know they didn't think about it - how ? 

Now there are still people believing it, without thinking for them selves. 

People are discussing it, and thinking about the different responses. Like adults. 

My neighbour still thinks the earth is flat. It's quite entertaining listening to his explanations and answers to my questions. Perhaps one to many St Pedro's special teas. 

Run the subject of cavitation or PR/FG knots past him - that's what this thread is about. 

My surfboard fins form cavitation...

No they don't. 

 ...and a mean bubble off the trailing edge.

Due to bubble entrapment similar to the venturi effect.

 Especially when not sanded blunt. 

Ever wondered why ? 

They are near the surface. Air is near the surface. 

Well spotted. Actually, air is on the surface. Everywhere. Fortunately.

From Dr Titahi's post "The effects of cavitation are especially important near the surface of the ocean, where the ambient water pressure is relatively low and cavitation is more likely to occur""

Now you're a Doctor Jason I'd go for a pay rise. Tell them Fish-i OK'ed it.

And Mike, up there for thinking, down there for dancing +) 

Mike knows. Let me rephrase that. MIKE knows.

Get out there guys.

Good advice

Dose of sunshine and saltwater needed here. 

Helps the fishing, and the thinking, and the dancing.

Oh and Smudge, looked up the definition of trawling troll. 

I tried too as well. Even Google was confused. Scary thought though - a troll who trawls. 

Think you may need some reflection on time on here vs time on the brine. 

I'm sure Smudge will be learning a great deal from this thread. If it wasn't for cavitation, anyone could catch gurnard.

Gotta love what you do I guess. Lter

You bet. Cya.

Thats impossible because there would not be a pocket of air due to the break(wave)if i was under the surface......But you are welcome to don your togs and dive down......hold your breathe and observe both knots in motion........The apoxia that would more than likely ensue.....Might do you some good.LOL.......maybe you could  actually contribute something to these discussions......rather than looking down your nose at othersWacko
