Calling is a tool. Used properly it will greatly increase your chance of success. If used wrong, it can hurt you. If you cant do it, you can it will greatly improve your odds of getting birds in range. Hunting the hot spot is great but you will be constantly chasing hotspots as when you burn them out, unless the feed is fantastic, they often dont come back. I like hunting near but not on the hot spot. I get more consistent shooting for longer periods of time but it takes some coaxing to get the birds to cooperate. Also, when the migration is on, calling is very important. It takes a lot of skill and commitment but is worth it in the long run. Maybe the areas that you hunt dont have a lot of pressure from other hunters and calling is not as important. I typically hunt public water and non leased fields and being a skilled caller is a must if you want consistent success.
