Since you're new to predator hunting/calling, my advice would be to start the caller and PUT THE REMOTE DOWN. LEAVE THE REMOTE ALONE. Let the caller run constantly. HOLD VERY STILL. Concentrate on seeing an animal, not jacking around with the remote. Scan as far left/right as you can only using/moving your eyes. When moving your head or any other part of your body, do it SLOWLY.
If at all possible, move when the animal is not looking in your direction or when it passes by or behind something that helps block it's view of you.
Colorado has smelled like one big azz brush fire every since 1-1-14.
