Though I will be “rebuilding” my air system when I go back to the USA, I still have my 1.1 L bottle which goes to 300 bar. This little bottle fits in a backpack easily and with air weighs around 3 lbs. I use this as an IN field bottle, on the move, not range tank for sure.
For my Taipan Compact I think I have an easy 4 to 6 fills which should give me 120-150 shots. I have an RTI Prophet Performance Compact coming in August it has a 300 CC bottle, so I figured that 1.1 L should fill the PP Compact’s bottle “2 times”.
For mobile I will get a larger tank hopefully a small portable compressor that is good for over-landing. Some of the small portable / car / truck compressors are able to fill / top off the 1 L bottles, so it makes for a perfect setup for the forest hunts.
