When I first hooked up withy my hunting partner he suggested i get the terminator bugle. He can reallywork that thingand whenI tried it seemed pretty easy to use...of course I only tried bugling with it. Any way I bought it but never could get the chuck to sound quite right. So I have now gone back to a mouth diapharam with the terminator tube. I use the primos imperial double palate mostly but also like the primos ivory for cow calling and spike squeals. They take a lot of pratice and in my caseI needed to trim the rear portion slightly to get rid of the gag reflex when I chucked. I have heard many instructional calling people refer to it as a musical instrument and you state "wouldn't expect to pick up a sax and play like Kenny G nor would you expect tolet it sit in the cornerfor most of the year and then play a concert in a week or 2". It takes practice: placement, exercise of the vocals/feeling and more practice to get the call working properly. I no longer just set my calls aside till the next summer,I make a habit of practicing through the off season to ensureI keep relatively tuned in with theaspects and it has made a big difference. A great way is pop a mouth call in while travelling to work in the vehicle, watching a game on TV or reading the paper/book.

Best of luck
