Hello everyone.

I am new to hunting and am looking to go with a friend(who has not hunted either) this weekend for some coyotes here in Arizona.

Since this is our first trip, we are hoping for the best but know that we very well may come back with nothing. But its all a learning experience anyway

So some questions I have are:
*Animals have keen noses, so do people smoke when waiting for their targets?
*Calibers can be too small to humanely use, but can a round be too big(say you are not going to keep the hide or whatever)?
*Would you recommend I get a digital caller for my first couple times, a reed caller or something else?
*Any tips you want to offer to help me be more successful?

Thanks everyone!
