We know very marvelous fish, Blackfin.
We love their attack breaking the surface of the rough sea and respect them.
We made full use of topwater and minnow plugs to catch them and found that they weren't hooked though they attacked such lures. We hadn't understood the reason.
One day, we synchronized a trial product, a sinking pencil lure, in a wave and could hook almost all of them which attacked the lure. We knew Blackfin could prey very well and have good sight. We discovered that it was more important to synchronize the lure in wave than to let it swim well in wave. In addition, a lure synchronized in wave was very natural for Blackfin. The method called "Low-tension-drift" was born in this way. Low- tension-drift was spread immediately among our fishing friends and became the indispensable method.
The point we aimed at is next.
1) When we hold 11 feet rod almost perpendicularly, the small resistance of this lure can make the moderate slack of line to synchronize a lure to a wave and the tide.
2) This lure keeps horizontal posture. So, seeing from a bottom, the silhouette of the lure is outstanding well. In addition, the lure keeping the posture is easy to synchronize itself to a wave and the tide.
Chimpan, a sinking pencil to catch Blackfin with 11 feet rod, is our answer.
