Probably more. There’s a built-in timing circuit. If you set the WAGGER for 8 second intervals, every 8 seconds there is only a 6/10th second pulse of energy to the motor. Very efficient. Until the pulse is sent, only the “electronics” are working when it’s on. Cold effects battery operation, so the power pack is made as a separate unit that you can bring into warmth without the deer decoy. Then, whenever you head out hunting, you can have warm batteries. In sub zero temperatures, it might be wise to enclose the power pack in a thick sock or mitten if you think you’ll be able to stay in your stand for an extended period.
