With goggle straps being under scrutiny at the moment, let's not forget that we are running about with bombs strapped to our markers in the form of HPA tanks. I saw an Angel Air tank for sale the other day, which was cutting edge technology about 14 years ago. This made me wonder.....how many of us are using a £1200 marker with an ancient air tank? Or how many of us have three or four guns, with only one tank? I have three tanks - all bought new within the last year - and five markers. Despite my flagrant disregard of the chinstrap rule, I do treat tanks very carefully, and haven't yet been vexed enough to throw my gun across the field. Who has more than one gun, and more than one tank...and how old are they?
