| A couple of recent posts on this board and others pertaining to sound and pressure pulse got me to wondering about something again. It seems almost everybody feels that spinners create a "thumping" or pressure wave in the water on the retreive. Yet Doug Hannon in his book Big Bass Magic claims that the spinner does not pulse or create disturbance in the water. I quote;
On pages 36, 37...
"You may not realize that spinnerbaits are one of the quietest lures you can pull through the water. This is because the blade runs in harmony (never changes direction) with the flow of the water. The off-center turning of the weight, like an out-oof-balance wheel, imparts vibration to the soft skirt or jig, and causes a wiggle. This transmits much less disturbance into the water than most hard lures."
And again later in the book on page 208...
"The spinnerbait swims almost totally in harmony with the water, making it take on the overall profile of living forage. Live food does not fight its way through the water, but rather swims easily and smoothly. The spinnerbait captures this profile to a T. Most anglers think the vibration they feel through their rod tips when fishing a spinnerbait is the result of extreme vibration that the lure makes as it is retreived. Actually, the lure creates little vibration or disturbance beneath the surface
Very little of this vibration actually enters the water, as oscilliscope tests have proven."
So, do spinners create vibration or not?

| Now I don't consider myself a pro by any stretch of the imagination but I can't see how those statements are true.
As the blade spins it throws it's weight off center. On a bucktail, I would think that this in turn causes a steady pulse wave to be emitted. On a spinnerbait type lure you need only look at the arm that holds the blade. As it moves through the water the arm vibrates back and forth. Each time the arm moves from one side to the other, it should create a pulse or vibration that is transmitted through the water.
My opinion is that if the blade spinning creates enough of wobble to make a skirt, bucktail or spinnerbait arm move, then it should also (in one way, shape or form) create some type of thump or vibration in the water.
Now the passages you quoted said that according to the oscilliscope, blade baits are among the quietest. They obviously put forth some effort to test their theory. However, I just can't see how that can be the case.
Someone more learned that me got anything to say about this????

| Well Scott, you may not consider your self a pro but your responce to Jay's thread is worthy of publication in any fishing magazine in my opinion, I totally agree with your post. I've seen muskies travel more than the lenth of my boat in a torpedo mode in VERY dark water to nail a bucktail, I truly think they didn't see it but was alerted by the sound or vibration it gave off. This is my take on the subject.[:)] |

| Jay,
With the new super lines and rods out now, you can really feel the pulsing and vibrating of most all baits. I troll more with spinners than I cast them. Trolling them, you can really feel the vibration. I have a hard time believing that the pulsing and vibration isn't giving off sound waves in the water. If you listen closely, you can actually hear the spinner bait as it nears the boat. The sound wave is traveling through the line and the rod which is what allows you to hear it. If I can hear it, then I think the fish can hear it/sense it.
Can fish hear??????
I think I will quit while I can.............. |

| Scott, yes fish can hear.... and very well I might add.
There is no disputing that "blades", whether on a bucktail or safety pin spinnerbait, displace water. Look at how much water a good bulging bucktail can displace. Geez, I can make a 3 inch wake with a #8 Colorado blade. That is a MAJOR pressure wave. Toss in the rotating nature of the blade and you now create a TURBULENT wake behind the lure.
What we are talking about here is WATER DISPLACEMENT, not sound. Not sure what the "oscillatory measurement" really was in the above posts.... but it doesn't jive with what I believe (but really cannot prove for lack of tools). When I'm fishing with blades.... I believe the fish FEEL the bait and react. Lateral Line, baby. If it weren't for lateral lines I don't think the bucktail would be nearly as effective as it is.
I think blades are quiet... but really move the water. That's all we need from them.

| Doug Hannon fan here and always interested in his perceptions but feel that some of what he is saying would not make much sense in light of what is easily observable on the water even by the less than scientific. JLong has a perfect example with the wake of the bulging bucktail, and if you would imagine a very large blade on a very large shaft rotating on a single axis you would realize that there is no symetry and thus can be no balance to the pulse emitted. An easy way to demonstrate the displacement and turbulence of bucktails and or spinnerbaits is to throw them in waters with a thick bloom on them or any area where muddy water mixes with clear.
You will be able to clearly see the turbulence left in the wake of your lures in these two situations.
For the bait to go unoticed it would have to be extremely streamlined like an airplane wing so the water would "mend" behind the bait. |
