I have a half lab, half vizsla and he's usually 200-300 yards away checking fence lines, farm equipment, etc. for birds and rabbits. I started with the collar on the lowest setting and would just tap it and call his name to come. On occasion I'll have to move the collar up to 2-3 to get his attention but almost all of the time it's on the lowest setting. He can be out of sight and I hit the button and he comes running. That's all I use it for, to get him to come to me when he's too far out.
