Mrzi me da prevodim, ako bude trebalo ti reci (ubaci u google translate i biće ti jasno). Suština je u ovome što je marenzi napisao, preciznost pre svega - u smislu rasipanja pogodaka. PCP je daleko skuplji i zahtevniji hobi od Spring-erice.
Spring powered
In the spring powered air rifle (springer), there is a piston and a coiled spring inside the chamber. The spring is compressed when you cock the gun. When you pull the trigger, you make the spring decompressed so it causes the piston to move forward. The piston movement makes the air compressed and the pellet is propelled out of the muzzle due to the force from pressurized air. All of this happens in the blink of an eye.
Pros
Simple to use
Cheap to buy
Accurate, powerful, consistent on shot-to-shot basis
Fully self-contained, no need for CO2 cartridges or pumping equipments
Helps you sharpen your shooting skills since springer often has lots of recoil
Gun parts are available in the market
Easy to service, modify or tweak the gun for better performance.
Cons
More recoil compared to other types
Requires practice to cock and shoot properly
Cannot be left cocked since the spring will be fatigued and might not function perfectly
Gets weaker if you shoot for several years, but can be modified for better performance
Precharged Pneumatic
The precharged pneumatic (PCP) air gun uses high-pressurized air in the chamber as the propellant force to discharge the pellet. The pressurized air is compressed up to 3000-4000 psi by using scuba tanks or hand pumps. When the air reaches a desired pressure level, the gun is ready to use.
Pros
Virtually recoilless
Compact, high power, high accuracy
Highly effective with large caliber pellets
Very little cocking effort
Most are repeaters which allow you to quickly shoot the second round if you miss the first shot.
Cons
Not self-contained
More expensive than other types
Need lots of charging equipments so there are more costs for the gun
