Interesting. Valkeen to be second choice to a fox 40?Valkeen. Pricey but OMG
Dolfin is another alternative. Brilliant for breaking up shoving matches and so on. Proper ear buster
I really like the dolfin, but in terms of pitch, it isn't much different from the fox 40, so doesn't do much to create a different sound from the next field over. The tornado and pearl mentioned above both sound significantly different from the standard fox 40
I should’ve added I have the basketball version which can be shrill. It’s comparable to the Sonik Blast
The Valkeen?£50 - really worth that much?
