Nike Unitized Tiempo Putter. New for 2007, the Nike Unitized Tiempo is a heel-toe weighted putter. Nike's seamless Unitized construction creates an express line straight from the putter face to your hands for unparalleled feedback. Human hands are most sensitive to vibrations from 100 Hz to 300 Hz - an optimal range that allows for the most tactile feedback. Traditional bonded putters generate a dominant vibration far outside the optimal sensitivity range. Unitized construction creates a powerful and sustained response within the optimal range for pure feedback which translates into better distance control. Constructed from CNC precision milled 303 stainless steel.
