The revolutionary Thunder Bugle is one of the best external elk calls ever made. The thin replaceable RT-Reeds snap into the mouthpiece in seconds.  With four different types of RT-Reeds you can produce a variety of sounds quickly.  Simply blow a breath of air through the call and apply top lip, bottom lip, or even tongue pressure and you will be producing tones so easily.  With a little practice you will be sounding like the real thing in no time.  The Thunder Bugle comes with two RT-Reeds, stretchy cord lanyard, camo cover and a cap to protect the RT-Reed.
