I just picked up one of those a few weeks ago, going to take it up to the Brooks Range and try it out in virgin teritory. Hopefully I'll be able to call in some wolves, cayotes, and bears. I sent Cass Creek an E-mail asking for a unit with Alaskian type calls on it, have not recieved any response from them yet. I like the compactness of this unit. Also the fact that it takes reguler AAA batteries. I also have the optional speaker and amp for it. It's real easy to carry the caller fits in one pocket and the speaker fit in the other pocket of my jacket. I'll let you know how it works.
