So I am racking up some serious credit card debt while going "all in" with Field Target. I have been exploring carbon 4500psi fill tanks. These companies are really proud of their bubbles of glass. So I priced a "great white" with all the fixings over at Topgun-Airguns and it was going to cost over $800. Then I stumbled upon a Air Venturi Nomad 2 4500psi compressor for $700. According to what I have read, it can fill most PCPs in under 6 minutes. My question is why go with a large tank over something like this compressor if you didn't need to portability (not that a 98cubicft tank is that portable)? Thanks for any insights you may offer.
