Reduce the effect dehydration can have on your deer herd with the Banks Outdoors Wild Water Watering System. Just fill the concealed tank and let it flow into the water trough or troughs, providing water for more than one animal at once. Once it's filled to capacity, the airtight system shuts off automatically until water is needed again. Plus, there are no valves or moving parts, which helps alleviate problems with your system.
