Its not so much the tube that makes a good sounding elk bugle, its the caller with a diaphram behind the tube that can make or break a elk call. But with that said one of the very best tubes for both huntingandcalling contests is the Monarch bugle tube from Rocky's Bugling Bull Game Calls. I think I own or haved owned almost every tube on the market at one time or another and this tube is the one of the best. Being honest I am a big guy and can blast it out there very loud, almost too loud for close up situations in hunting,so for hunting I don't need as big of tube so I carry one a bit smaller. For contests I have made my own tubeslike the majority of pro callers do. This Monarch tube is patterned after the tube that the pro's have been using for years. Not trying to say that Abe's tube is junk because its not (yesI do own one)but the Monarch is just all aroundbetter!
