Got my MA-15 today. threw in some batteries and went out on the deck to check it out. No critters in sight. Put on the crows mobbing, and crows messing with a horned owl.
Took all of 30 seconds and 20 crows were circling overhead and landing in the cottonwood 20 yards away. The first 4 came barreling in to the speaker, and would have been a 15 yard shot.
Also tried coyote howls, cottontail distesses, tom turkey, whitetail buck grunting and snort-wheezing, and a couple others. The neighbors are getting pissed.
This thing is awesome. No way I can crank the volume, been running less than half throttle.
