Flatline 20-40# 7' Live Bait Spinning Rod

The Flatline 20–40# is Gulfstream Custom Rods' versatile live bait spinning rod, specifically designed for anglers targeting kingfish, sailfish, mahi, blackfin tuna, cobia, and other pelagic species with smaller live baits.

Unlike heavier offshore spinning rods, the Flatline 20–40# was engineered to maximize bait presentation while maintaining the fish-fighting power needed for demanding offshore conditions. Designed to fish pilchards, threadfins, herring, sardines, and other live baits, it delivers the perfect combination of casting performance, sensitivity, and backbone for a wide variety of offshore applications.

Built on our Gulfstream Diamond Tek Composite blank and equipped with premium Fuji Silicone Nitride (SiN) guides, the Flatline 20–40# provides exceptional casting performance and durability while maintaining the strength necessary to handle hard-fighting gamefish around reefs, wrecks, bait schools, and offshore structure.

Whether you're fishing the Florida Keys, Miami, Fort Lauderdale, Palm Beach, or the Gulf Coast, the Flatline 20–40# has earned a reputation as a dependable offshore spinning rod for anglers targeting pelagic species with live bait.
