RE: Preymaster e-caller?
Hand calls still call in more predators than all the Ecallers combined. A guy can buy lots and lots of hand calls for the price or an Ecaller, and the batterys never run out on hand calls.
Don't under estimate the hearing ability of predators. They can hear hand calls from a long ways away.
I don't use any Ecalls, but still call plenty of coyotes.
