If you spot a bear you may be able to pull him a bit closer with a call but he may very well ignore it...he also might just take off. If you plan on going into the woods, blowing a call and seeing a bear show up looking for a meal you're in for a LONG wait. I've called in some of the highest BB density areas in north america and never had one come in. I've also tried calling one back after being busted on a stalk and he couldn't care less about anything other than getting the hell out of there, Are you planning to hunt spring or fall? Best bet is find the food sources/travel corridors and hunt those.
