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