What is the difference between BB² & XX?

Both Big & J deer attractant products are derived from the same nutritional requirements of deer, but XX is a more concentrated formula intended to provide more minerals and an increased protein level. This allows you to mix the product with up to 10 times as much of the weight of the bag without diminishing the attracting qualities of the product. BB² was developed to either be used as a stand-alone nutritional deer supplement/attractant or to be used as a top dressing agent when using other deer feed sources to provide a nutritional attractant.
