The Nitro is part of our 2012 anniversary series. This is a full range call, from open water, to the timber it is right at home in any Water fowling paradise. Loud, raspy, to low and nasty this call is pretty much like no other. Back bored, double O-ring sealed, and all the other bells and whistles. Made right here in our shop to our exacting standards. Available in a single reed. Pick up the Nitro and burn them down this season.
