First of all, welcome into sport.
Second, this question should be ask in the new player forum.
That said, every marker has the same "power". The only way to improve the distance reach by a ball is to get a special barrel, like a tippmann flatline.
I understand that you currently have a mechanical spyder. If you want to improve, check for electronic marker. They will allow you to shoot faster (more balls/sec). However, they won't shoot farther. If you want to improve accuracy, get an aftermarket barrel, and think about HPA tank : HPA is more stable than Co2, help to stabilize shots and can shoot faster without freezing.
I hope this answer some questions, have fun and play safe.
