Hello all.
After some assistance.
Can anybody who has Senho soft stick baits do something for me please?
Measure accurately (either mm or parts of an inch - but accurately) the diam of a couple of the lengths that you have and use.
Was asked a question about why and how Senko "rubbers" work recently and want to "value-add" to my response. Tks.
Soft plastic Senko
Re: Soft plastic Senko
You might want to check out Do-It Molds, they are the only Yamamoto licensed Senko mold maker. I am guessing you could find specs on the bait there.
Don't ask about my username, all I need to say is check yours and check them often.

Re: Soft plastic Senko
I measured a 5,6, and 7" senko for you.
The best I could do because they're soft and my eyesight has went to shi# the last couple years is"
5" senko .36"
6" senko .40"
7" senko .50"
The measurements were done on the most sensitive equipment Harbor Freight has to offfer.

Re: Soft plastic Senko
Thank you, Whoopbass.
I can't get Senkos in Aus. That's why I asked for help. Take weeks to get them here from US.
Eventually found some in China which are already on their way. Have thought of a use for Senkos with catching a fish called a Polydactylus Macrochir( king threadfin). Grows up to 1.7m (almost as big as those Florida tarpon) and inhabit estuary mudbanks and shallow creeks here.
Can tell you what frequency, beats per minute, rpm that the sizes that you sent me translate to.
A lot of your guys call it quiver. We call it vibration rate. Means same thing.
5 inch...36 ins...9mm = 630 beats per minute = 10.5 Hz (frequency) = QUIVER RATE PER SECOND
6 inch....4 ins...10mm = 567 beats per minute = 9.5 Hz ( frequency) = QUIVER RATE PER SECOND
7 inch....5 ins...12.5mm= 453 beats per minutes = 7.6 Hz ( frequency) = QUIVER RATE PER SECOND
Having got that figured, all we need to know is the response rate of a LMB lateral line. Same as all LMB.
Note that as the worm diam increases, the "quiver rate" decreases.
Whenever that Senko is moved in the water, it sends out a quiver (vibration) commensurate with its diameter. The longer the worm, the greater the quiver magnitude.
The magnitude/amount of quiver depends on its length and the quiver rate depends on its diameter.
THAT'S the principle by which Senkos and similar lures work.
Knowing how/why something works is half the battle. Then u can work out specific methods to suit your type of fishing without having to work ur way through the confidently wrong and smoke and mirrors confusion that abounds.
Now you know. Make the most of it.
Long Senkos have an awful lot of empty space along the body where there's no hooks so there may be a lot of hits but fewer takes. Have you experienced that?
From the attached, you can also see that the Senko "quiver" (vibration rate) is all under 600 beats per minute ( 10 hz) so will generate "quiver" perfect for the response rate of a lateral line.
If u want to generate "quiver" across more of the response band, have a Senko or equivalent with a tapered diameter.
Start with 630 beats per minute ( .36 ins diameter in middle) and taper the diameter down to .25 or .3 inches at each end.
That'll give a "quiver" range from 10 hz (630 beats per min) up to 15 Hz (892 beats per min Quiver rate).
A single quiver will then send out a band of frequencies ranging from 630 hz to 892 hz. A frequency sweep.
Or you can taper from 10 hz ( .36 ins in the middle) and taper up to .5 ins (450 beats per min) to each end. Another frequency sweep.
That term sound familar? It should.
A freq sweep like that is a mechanical way of generating "CHIRP-like" signals without all the sounder "throbatrons and microchips" (and cost).
Nothing new in this world is there.
The overall average quiver would be between 630 - 892 "quivers" = 761 (quivers) = 12.7hz.
If u tapered up the average would be between 630 - 450 "quivers" = 540 "quivers" = 9 hz.
You don't have to be exact. Just know that if you taper up, the quiver rate drops.
If you taper down, the quiver rate rises.
That's all you need to know.
This Senko stuff is an example of how knowledge of how the thing works avoids all the smoke and mirrors and the confidently wrong info flowing from the gurus and ego brigade. A more informed starting point for fishos.

Re: Soft plastic Senko
Ronje,
Largemouth bass around here don't typically bite, they inhale the bait, so one hook is usually plenty.

Re: Soft plastic Senko
Thanks Mark
I know that they are bite "inhalers". More commonly known as "suction feeders".
Is there an increase in misses with long Senko style worms though?
Like our famous barramundi, they have evolved with no teeth for gripping/holding. Expend less energy that way.
Can't bite but can give a nasty suck.
The threadfin I was telling you about are normally "ram feeders" but in the shallow mudflats also use their long pectoral whisker to feel for food and "shovel" it into their mouths.
I saw some videos of LMB trying to suck down a long Senko style worm. Kept going for where the hook wasn't. Might have been that bass wasn't big enough to suck in a long worm in one go although they aren't called "large mouth" bass for nothing.

Re: Soft plastic Senko
If I fish a Senko it’s normally the bigger 6-7”. Wacky rigged. Rarely miss a bite. 2/0-3/0 shiner hook. No o ring.
Re: Soft plastic Senko
Thank you Dave.
6 - 7 " eh? Your experience sounds encouraging. As I said they aren't called large-mouth bass for nothing.
I'll have to look up what "wacky rigged" means.
Anyway, the purpose of the original post was just to show the principle of how they worked.
If fishermen like you are already successfully using them, then you don't really want to know how they work.
The post was to show a couple of "experts" who'd made some silly claims about it and apparently have been spreading that "silliness" to newcomers creating confusion. There's a lot of them "out there" and about a lot of other subjects as well. We have 'em over here too. Members of the Bathwater Drinkers Guild (each others).
For a newcomer, it really becomes a case of "which expert do I listen to 'cos they've all got different hobby-horses to push" ?
Have a good Xmas, Dave. Its "pi..ing down" rain here. Hope Santa's got his w/screen wipers working.
regards
