The Seedmaster Vibrating Hand Seeder is a scoop-type tool that, by turning the wheel with one's thumb sows even the tiniest seeds quickly and precisely. Rotation of the wheel results in a vibrating action that causes the seeds to flow evenly from the device's "seed bin" through a baffle inot an inti-static "V"-shaped channel and out onto the soil. The stronger the thumb pressure, the more pronounced the vibrating action. The Seedmaster comes with four different baffles to accommodate seed sizes.
