I used to run the electronic rabbit distress call, but found that it was the same sound over and over and the coyotes are way too smart for that. I ended up buying a Sceery cottontail distress mouth call. Absolutely love it and you can produce so many different sounds that are more realistic. The problem I am having is: Its a closed reed call and moisture will make it quit, and this morning it was worse since I was out of the vehicle, it froze up all together. Would it be a mistake to try some type of water repellent or even lock de-icer on it, while out in the field?? Has anyone else experienced this problem??? Once I got back to the vehicle, I set it on the defroster and heated it up....worked fine after that. Darcy
