Your air source powers every shot. Understanding CO2 vs HPA helps you choose the right tank.
CO2 Tanks
Lower cost, easy refills, but temperature sensitive and inconsistent pressure.
HPA/Compressed Air
Consistent performance, temperature stable, required for most electronic markers.
Tank Sizes
- 48/3000 - Entry level, about 500 shots
- 68/4500 - Standard, 800-1000 shots
Aluminum tanks are affordable; carbon fiber is lighter but more expensive.
