I have been refereeing US soccer for about 21 years now. This is by far the best sounding whistle I have used in all my years. On top of that the price is extremely reasonable compared to others of similar town.
For anyone officiating outdoor sports events I highly recommend this product.
Love the pitch, quality and effortless sound.
My Dolfin Pro (Actually Dolfin F) arrived today. Great whistle! More solid and substantial feel than regular Dolfin. It appears to be perhaps 1/8 of an inch shorter. As claimed, the sound quality seems indistinguishable from the Valkeen.
Finally I tried one of my Valkeen flip grips (Medium/20) on the Dolfin Pro and it works perfectly! I typically use the Small/18 on my Valkeen, but the Medium/20 worked just fine and, in the hand, had a nearly identical feel to the Valkeen! All in all, this is a great whistle and an excellent choice for those who want Valkeen performance at a more affordable price. Except for minor aesthetic distinctions, the World cup model of the Dolfin (comes with flip grips) F will give you the full Valkeen experience.
