The VIPER – another TRIED & TESTED fox call from Best Fox Whistle.
Based on the same design as the best selling Best Fox Whistle SS, and the Blaze, the VIPER offers a similar raspy sound.
What makes the VIPER great is the addition of a couple of ridges, making it really simple to use hands free.
And if it’s minus 10 outside, it’s not so cold on the lips.
Some have said it’s also a little easier to master than the SS – so there’s another good reason to give it a go!
3D Printed with durable PLA plastic.
Capable of huge volume – up to 120dB and exceeding 22,400 Hertz.
