The Threat Elk Grunt Tube is a new, revolutionary invention from Rockie Jacobsen. The Threat features the new V.E.T.T. (Volume Enhanced Tone Technology) system that creates true, easy to obtain elk sounds. The V.E.T.T. system uses a stpring, tuned specifically to the right dimensions, that is inside the mouth of the new style bugle tube. This spring creates more volume and stabilizes high notes, takes less air to operate, and makes raspy, low growls, easy. It truly enhances the sounds you make to sound more like an elk.
The Threat Elk Grunt Tube is small, at less than 18" long it is easy to pack. It also features a smaller 1" mouth opening and tapered lip adapter that make it easy to control and create sounds using a diaphragm call like the Raging Bull, All-Star, or any other diaphragm call of your choice.
The Threat Elk Grunt Tube also features a tube tamer/vibration dampener on the inside of the large end of the tube that enriches deeper sounds, to help with grunts, chuckles, and eliminate plastic vibration. The Threat is the best bugle tube we've tried here at Altitude Outdoors and we highly recommend if for your upcoming hunts!
