Prowla Anti-Tangle Tube Sinkers can be fished with a float rig or on
a straight ledger. Simply thread your main line through the tube, tie on
your trace and pull the trace swivel into the rubber tube. This gives a
semi-fixed weight and helps to prevent over wraps and tangles when
fishing in deep water. The tube sinker offers a quick-change ability
working in exactly the same manner as Prowla Quick Change In-Line
Sinkers. Simply pop open the weight stem, slide the lead off your line,
replace with the desired size, and click the stem parts back together.
