hey johnny2 if you are mainly going to hunt crows and arent worried about spreading your scent or getting seen out in the open like you have to worry when coyote hunting I would get a johnny stewart preymaster they cost about 100 dollars and a crow card cost about 20 more,I used one for several years and it works great,it's plenty loud and I have killed a truckload of crows with mine.I just sold mine about a month ago,it was just getting dusty sitting here.The main advantage of the foxpro for me is I can set up easier without being seen,but for crow hunting I would just set the speaker in the decoy spread start calling and let the feathers fly,they arent worried about what you smell like or all the scent you leave from your hands on that wire to the speaker.Hope this helps,I am not farmiliar with the call you mentioned???
