Abstract: A strike indicator float or sinker is disclosed. The device preferably having a rigid insert having two opposing clamping sections. The sections are joined by a hinge, preferably a living hinge. The opposing sections have a tab that is configured to retain a free side of each opposing face in a clamped together position. Each opposing section has a internal face configured for positioning thereon a fishing line. The opposing surfaces form a generally flat section and recessed flat section that are configured for mating engagement. The flat sections are preferably configured with an overlayment of rubber or molded plastic to increase friction between a fishing line positioned in the opposing flat section. The flat sections provide for lateral adjustability of the fishing line relative to the center of the device. Two hemispheres are positioned on the opposite side of each opposing section from the clamping sections.
