What kind of spider is this?

My uncle and I were cleaning the pool filters today and he lifted the bucket out and I saw this beast on the side, and told him to drop the bucket. at first I thought it was a tarantula, but then i thought that it wasnt because it wasnt big enough or hairy enough, even though it was both of those things.

If youre good with spider identification i would really appreciate a gander at this pic, thanks for the help!

I just asked this question, but didnt get any answers within the first 10 mins, which is usually a bad sign so i reposted
