Hook’s Custom Calls and the GrowingDeer team spent months studying hundreds of trail camera videos of grunting bucks. This research of free-ranging bucks was the basis for the sound, tone, and volume of the Messenger grunt call!
This call has three settings; the top setting is intended to imitate the grunt of a doe or a 1.5 year old buck. The middle setting is intended to mimc a 2 to 3 year old buck and the bottom setting is for imitating an older buck.
A grunt call should communicate that a receptive doe is nearby and not committed to a buck. This is an open invitation for other bucks to come close and seek out the receptive doe.
