Water Gremlin’s Low Profile™ Slip-Sinkers are made super tough, so they won’t dent up when banged on the rocks. The perfectly round hole stays round, with no jagged edges, so it doesn’t fray your line. With its full-length, streamlined shape and concave base that covers the nose of the worm, the Low Profile™ is uniquely designed to go after hard-to-get-at bass. It allows your rig to sneak through weeds, moss and brush while minimizing tangles and hang-ups.
