I am wondering if I am adding an extra step for nothing. I will be doing my shooting at home where I have a Benjamin Recharge compressor that has lots of safeguards including an automatic shut off at fill level. The compressor will be set up in a walk-in container at my little home range. Do I need a scba tank? Isn't that just adding more stress to my compressor on topping off an 88cu tank as compared to topping off my PCPs? What would be the benifits of having a tank on hand besides traveling to a range or something in which I do not see me doing for a while. Thanks in advance.
