A composite of E-Glass fiberglass and uni-directional 30 million modulus graphite make these the newest and lightest saltwater blanks available. SEEKER™ has done extensive research on mandrel and pattern design to offer the ultimate in a composite blank. SEEKER'S™ resin system, E-Glass and graphite are combined so that there are alternation layers in both materials in the butt section on the blank. SEEKER'S™ unique use of E-Glass provides unequalled durability and strength throughout the length of the blank while the unidirectional graphite adds stiffness for hook setting and fish fighting power at a 30% to 40% weight savings in the blank!
