5 inch Scent or bait tube with adjustable gate. Three sponges are included and is made with all stainless steel hardware. Can be used for Ice Fishing, Bank Fishing or Boat Fishing. Simply add your favorite scent or bait into the tube, adjust the gate at the end of the tube to allow the scent line you want to create, attach a rope or cord,  place it in the water and bring the fish to you. Add a pool noodle for floatation if fishing from the bank (not included).  This will also attach to the 8 or 10 lb Scent Distributions System in place of the 3 inch bait tube to extend your bait capability.
