Tsunami Carbon Shield II Boat Popping Rods are designed with ALPS Guides. Premium Hypolon grips for maximum comfort. Made with feather light IM7 graphite blanks with D16 nanotech and unique carbon fiber design. D16 Nanotech blank technology consists of multi-directional layers of IM7 carbon fiber that have been injected with nano resin and wrapped in 8 different angles which evenly disperse flexural force in 16 directions. This combination provides an extremely lightweight blank that resists twist and adds hoop strength. These rods make casting to, hooking, and fighting big fish as easy as it gets. Great choice whether you are jigging Tuna in the Northeast or battling Grouper down South.
