True Frequency Lacrosse Heads come in 3 styles; a Speed Head, Universal Head and Defense Head specifically designed for the different positions on the field to offer maximum position specific performance. True designed the Frequency Head with precision and craft to create a very impressive first offering in the head category. The Frequency Head goes back to basic geometry with triangular sidewall rails and inverted cut outs to increase overall strength while reducing weight. For added stiffness and durability True Frequency Heads use a triangular strut design from the scoop to the throat for well balanced stress displacement. True also paid close attention to how the Frequency Head would string up as well, with 21 sidewall holes varying in shapes and sizes this head can string up with the best of them. Each of the three styles of the Frequency Head have a different bottom rail design for each position specific pocket. True did an amazing job of designing and developing the Frequency Head, don't be surprised if you see this head all over the field this up coming season.
