I’ll be buying a co2 tank.
If someone in the trail 4, 5 rigs in front of me gets a flat and no one can supply them air. It will be easy for me to run up there with the tank and supply them with air. I can use it around the house. You can clean out your guns with the air. Doesn’t have a duty cycle so no waiting on the compressor to be ready. You can also run air tools if needed. No moving parts unlike a compressor many things can fail overtime and if I remember correctly a co2 tank is faster at inflating tires.
