go for a HW100
Good choice. I have one. Stellar performer.
manual pump unless they’re totally impractical?
Two considerations based on my ownership of both pump and dive-shop filled cylinder:
- The effort to fill the HW100's cylinder with a foot pump is non-trivial. You will be a tad flushed at the end. Which is fine, but plan to have a period of time separating pumping and shooting or the crosshairs will wobble on target
- When serviced recently, the Bellville spring washers in the regulator were slightly rusty. That was ascribed to using the foot pump which does not scrub moisture out of the air. [dive-shop filled tanks are sources of very dry air by comparison]
One other consideration for O-ring longevity: if not in use for extended periods, screw the HW100 cylinder out until you hear the air release. If stored in situ, the breach and breach seals remain under constant presure.
