I have the moj super critter and I really like it for the fact that if my caller dies out in the field I can switch it to the sound and motion. Its not very loud, but I will use it with my hand calls. They hear my hand calls, I see them coming in, I stop and then they hear and see the critter and they are focused on its sound and movement. Thats why I like it. However thats how I have it played out in my head anyway. lol
