Over the years I have used quite a number of elk calls including Glen Berry's stuff, Larry D Jones calls, Carlton, Primos, Abe & Son, etc. I even made grunt tubes out of my mother in law's vacume cleaner hose. With a home made camo cover that hose worked as well as any, and better than some Carlton and the Abe & Son call for me. For the last few years I have used the Lil Chuckler as my exclusive grunt tube. Except for the rare time when I might want to sound like the biggest and baddest bull in the woods, that grunt tube along with either the Primos red diaphram or the Ragin Bull red diaphram sounds the most real and appears most convincing from what I can see. Those diaphrams work very well as cow calls too, but I also still like the little Larry Jones "Cow Call". The Jones call is usually more than adequate and it is very handy. I just wear it as a neckless so it is always ready.
