摘要: A convenient electronic sound producing device is an that physically configured to be easy use in the field. control module faces while projected away from user. pistol grip can used ease holding and using call. remote further operation allow a distance. timer allows for nearly autonomous operation. Control modules fixed firearm, bow, crossbow, or camera minimize user's movement simultaneously calling preparing shot. pinning hole stake reliably fixing surface, vegetation, other objects.
