Call question

[mohunter82]

So here is my question. will a muture buck recognize calls. I use 2 different grunt calls. a Knight and Hale EZ grunter, and a Lohman 5-1. Along with a Knight and Hale rattle bag. i used these to get the same shooter into my sight twice in the same day but I worry that he may begin to ignore them if he recognizes them.
What do I do?

I wouldnt worry.If he thinks its real now he should think that later. But, maybe change up the sequence, different tones, or make them vary if you're worried.
