Darrell Gibson is the one to go to , he sells his handmade production calls through Midwest call supply and CrowMart . These are his standard long range and the short mag .he also sells from home and he has a few more styles that has just been released the Stubby and the Fatboy Jr. . Both of these calls have great sound for locator and are the best crow sound that I have heard. I work with Gibson on calls and also have a few of my style that I used his tuned mouth piece. I just posted a picture of one in the general forum , it will be going to classified in a while pm me for Gibson contact info
