Does anyone else use this method to tell if a tank is full before hooking all the gear up to it? I always check pressure before I splash on my spg but have never seen this method before.

If nothing else, it is wort watching the clip to hear them play Mary had a little lamb with tanks.

i use it when we have lots of tanks laying around and don't know the empties from the full ones. it is alot faster than hooking up 3 different tanks to see if you grabbed a full one.
