The best time to call is when you actually see a deer, that way you know if it heard your call and how it's reacting to it. Blind calling should be avoided.
I would respectfully and totally disagree. I've called in A LOT of bucks calling blind. Most of the bucks I've killed during pre-rut/rut were called in blind. During these periods, I will call anywhere from every 15 mins to every 30 mins, depending on the stage of the rut. It's easy to over-do it though. You have to becareful. I like to call often, but in very small amounts.
