Professional whistle, Fox, Classic, 115 dB, black color

Get rid of the classic whistles that use the classic straggler and get a FOX40 today. What makes FOX40 the best? A croak whistle creates the sound by the movement of the small feline crocus inside, alternately closing and opening the hole where the air escapes. This process produces rapid alternating sound and silence, the characteristic vibrato hiss - until the straggler sticks in the hole. The FOX40 Whistle without Crook is more like a harmonic instrument as it produces 3 slightly different frequencies simultaneously. The different frequencies are superimposed on each other, and thus alternate and cancel each other. The result is a loud, piercing vibrato whistle that has no moving parts inside to stick. The whistle is plastic from a mold and is produced by the injection method. FOX40 CLASSIC CMG The Fox 40® Classic® CMG® is the improved version of the Classic, as CMG (Cushioned Mouth Grip) has been added, a thermoplastic material that gives protection, and grip.
