The dependent version weighs 18.5 pounds (8.4 kilograms) and requires the backpack unit in order to generate smoke. The high capacity backpack weighs approximately 22 pounds (9.9 kilograms) and is equipped with a 64-ounce (1.89 liters) fluid reservoir and compressed nitrogen cylinder. This system provides a six-fold increase in volume of available materials for aerosol production. The principle difference between the standalone and dependent system variants is that the hand-held gun portion of the dependent system does not have an integrated fluid media reservoir and nitrogen source. The dependent version (with high capacity backpack) is capable of dispensing over 320,000 cubic feet of smoke on a single charge.
