I have noticed that a lot of people don't realize just how loud they are playing their E-Callers as they have the caller speakers pointed away from themselves and setting out in front of them a few yards . The speakers are directional and from behind them you really can't tell how loud they are . If you want to tell just how loud they are set them out then walk down range of them with them playing . Take into consideration that the animals you are trying to call can hear better and in more frequencies then most people can . I like to play sounds that are in season at the time I'm calling as an example pups, fawns ect. are born in the spring . baby rabbits and adult jack rabbits ect. have young all year long . There are times that you will get coyote to respond out of curiosity to sounds that they wouldn't normally hear at that time of the year and that is why I listen to the animals out there in the field to tell what sounds they are making at what times of the year
