I love my primos buck roar (it has a snort/wheeze obviously) I've used it on smaller bucks in early season and they get curious (sometimes) and come in. but I would call it a must have if you are in the Rut and see a monster headed past you with his ears back and head low cause he might not give you even a flinch with an aggresive grunt. its really up to you watching that deers body language when he's comin in, if his ears are up and if he squats and looks like he's gonna spook with every snapped twig then he's wayyyyy too timid to use that on
