Tubertini Pro River 2 Pole Floats. Tubertini Pro River 2. Another brilliant alround river float with a carbon stem & plastic antenna. The body has a more diamond/rugby ball shape than the Pro River 1 & also fished well on both short & long lines. The Stem & Antenna gauges are reduced in the smaller versions making the Pro River floats ideal for different venues & situations across the 0.50g to 3g range.
