Breakaway rigs allow the line to snap free from the top anchoring point of a float when a fish takes off with the bait. The simplest breakaway rig is a fixed-float system: Thread two silicone bands or surgical rubber tubing on your line and run them up to where you want the float anchored. Normally, on a non-breakaway rig, one band is slipped onto the bottom of the float, one onto the top. For a breakaway, however, use three rings. Jam two bands onto the bottom stem of the float, anchoring the line securely. At the top of the float, fold your line into a "U," tuck the fold beneath the third silicone band and slip that band over the top of the float, making sure the line running the length of the float is snug. Now, a hard-running fish, or a snap of the rod, will pop the loop of line from beneath the top ring, allowing the float, still firmly anchored only at the lower end by the double rings, to pull through the water with far less resistance. The less line stuffed beneath the top band, the easier the breakaway.
