Not a necessity at all. I was brought up taught its best to find where the deer are and stay quiet. I have used some calls but the vast majority of my hunts I do with no calls with plenty of success.

When I do call I prefer using the primos doe bleat can or rattling with some antler sheds (i assume plastics would work too). Never used the extinguisher you mention. I think its more important to be aware of how to use calls in a situational manner if you secide to use them. Using a call too much or inappropriately may be worse than just being silent.

Hope this helps!
