Gamo Swarm Magnum VS PRO

So I noticed on gamo's website they have

and

they're both .22 Swarm Magnum's but one is a "pro". what exactly does the "PRO" have that the "regular" one doesn't?

EDIT: ignore that one is a bundled kit. im just using that page to reference the rifle. its visually different from the PRO so im curious what all is different about it.
