here is where you get the power howler that everyone was asking about. but the key to getting it to reach out is the horn.
http://www.elkinc.com/detail.aspx?ID=13you can normally find them at the local gander mountian. I have had a hard time finding them at cabelas but since gander mountian is closer i normally just get it from them. also they are cheaper buying from a retail chain. normally around 15.00. if anyone would like me to show them a easier way to blow on it to get good howls and barks then next time you see me ask me and I will be more then glad to help you. takereasy. ben smyser
