Logan Turbo Brass whistle with etched working Collie

Two hole TURBO whistle. Machined from solid brass ( no rivets ). Same shape and size as the Supreme and A1 but the twin holes make this much louder than a traditional whistle.

The Turbo design affects the timbre (or 'voice') of your whistle tones in a way that really helps them cut through interfering sound.  It has the capability of even greater volume for those who work at distance or where there is the possibility of a lot of sound interference.  

Weighs 20 grams, measures 4.8cm at the widest point.
