Molten Valkeen: Used by many FIFA referees. Highest dB out of all pro referee whistles (127.6).
Buy here: www.amazon.com...
Acme Tornado: Also a popular FIFA whistle. It's got the highest frequency rate out of all pro referee whistles and therefore sounds higher than the molten for some people.
Buy here: www.amazon.com...
Pro Match Unique: Very similar to the Fox 40 and and also the Acme Tornado 2000. Cheaper than both.
Pro Match Taifun: Also called "Devastator", The 3rd most expensive whistle in the video. Actually more expensive than the Pro Match Unique.
As you can hear in the video the sound completely differs from the other whistles and it can not handle full power. Not recommended for referees who want to advance.
