The results of this rattle experiment reveal which rattles fish hear best.
Last month I detailed an experiment conducted years ago.
In a nutshell, scientists and anglers got together to test rattling lures in a tank to determine which ones could be heard by fish and which ones could not.
You can read that article here.
Fish (specifically bass) best hear dominant frequencies below 1,000Hz.
It’s likely fish can’t even hear the rattling lure you’ve had in your tacklebox for years.
Yeah, I know.
It’s sort of a letdown when the whole idea behind a rattling lure is to attract fish using sound!
The lures that were tested had different kinds of BBs inside them.
Some were large, some were small, and some were glass and others metal.
The experiment pointed to large beads as producing a lower dominant frequency than smaller beads.
Whether glass or metal was better was not specified and, of course, specific brands weren’t mentioned for legal reasons.
While we don’t know which exact lures were tested, we do know what is required to make an effective rattling lure (or cork).
This will help us determine which lures are best!
Perhaps in the future I will take apart a few of my lures to see what they have inside of them.
And, so you know, I read about this experiment inside the third book of In-Fisherman’s Critical Concepts series for bass, which is a series of three books detailing pretty much everything about bass fishing.
