Hello, I am fairly new here and haven't varmint hunted in a long time and have a question or two. How long do you call for initially? Do you call continuously or stop and start? Normally I start off low and cal for about 2-3 minutes and then wait . I get progressively louder the next sequence. After that i vary the tone and length. Am I doing OK or do I need to change tactics. I have only hunted a couple of times this last month without much success. I am using a open reed mouth cal primarily but also have a tape setup as well.. Steve
