I'll be getting the hand pump with it. I don't know if I mentioned it but I owned a FX Black Widow (PCP) in .22 cal. for a while. I have the scuba tanks already because I dive on occasion.
The scuba tanks are great IF you just want to sit in one spot & plink away a tin or three of pellets, but the hand pumps are not all that difficult to use. I'll probably buy a few bulk co2 bottles in case something happens to the pump though.
The only reason I sold the FX was because it was too loud & the neighbors I had at the time, weren't too keen on my thinning out the squirrels.
