Molten flute Dolfin
Professional referees whistle for football, volleyball, hockey, handball and more! The Dolfin F is characterized by a high tone and longer range. The unique shape - with openings on four sides of the whistle - helps maximize the high pitch so that the whistle can always be heard, whether in a gym or in a noisy stadium.
Whistle without pea.
