Thill Bobber Spring Float (UAC)

Thill Classic Spring Float (UAC) – Traditional Design & Unmatched Sensitivity

Step back into the gold standard of float fishing with the Thill Classic Spring Float (UAC). These high-quality balsa wood floats are the go-to choice for anglers who prefer a fixed-depth presentation. Designed for quick rigging and instant bite detection, the UAC series remains a staple for targeting panfish, trout, and walleye in shallower waters.

Product Overview

The Thill Classic Spring Float features the iconic high-vis tip paired with a premium balsa body. Unlike slip bobbers, these are fixed floats, using a stainless steel spring to lock your line at a specific depth. This makes them incredibly efficient for fishing over submerged brush or along weed edges where you need to keep your bait suspended exactly where the fish are holding.

🎣 Pro Tip: The Quick-Change Rig

To avoid damaging your line when using a spring float, always pull the spring down before tucking the line into the notch. If you find your float is sliding during a heavy cast, wrap the line twice around the hook notch before releasing the spring; this "double wrap" provides extra grip on fluorocarbon or slick monofilament lines without causing kinks or weak spots.
