  • Patent number: 5231787
    Abstract: Stable Bobber for Rod Fishing consists of a stream-line conic rod with a plurality of proper holes at the side of its lower portion, or with two stream-line sections in reverse direction wherein one section is formed by cutting off its lower portion; these two kinds of bobber are either suitable for an open water region or for a close water region and are both very stable and sensitive. When the bobber is floating on the water and the color-striped post is affected by discontinual resistance force from waves and wind to oscillate and fall on the surface of water, the bobber can turn its stream-line to the proper direction and maintain itself upright and stable either by rotating itself to balance the back pressure or by gaining a negative pressure, and thus maintain its stability and sensibility.
