This fox call from Nordik Predator can be used without the use of hands so you are flexible with the rifle in fast hunting situations.
The unique membrane provides additional sound dimensions of pain and anxiety. By biting and blowing in the calls ends, you can produce virtually any general distress sound which is necessary for effective hunting of predators.
The membrane is wide on one side and narrow on the other, so you get different tones depending on which side you blow.
Blow the broad membrane and get a darker distress sound. Blow the narrow membrane to produce a lighter distress sound.
You have three locations from each side. If you bite in the middle of both sides, you get a bass sound of the cry of fear. With every step towards the edge of the call, you can adjust the sound / tone as you want.
Volume is adjusted depending on how hard you blow the fox call.
