there are no local freedivers in Jeddah. I was there last July for a 10day liveaboard and the operators watching me freedive thought it was the second comming, alought their boat had a big OMER sticker on it.........
Jeddah offers some great freediving and spearfishing, Yambu is far better though.
lots of wrecks and deeper walls to dive, and the with viz aproching 120ft on some days, it's hard to ask for anything more. if you're used to BC waters PLEASE BUY A DEPTH GAUGE. it's very easy to find your self far deeper then you want to be in those crystal clear waters
Also expect to see some "interesting" Darwin-was-wrong diving practices
"good Luck" is my best advice for a rookie in Arabia.
Also, drive the biggest vehicle you can aford, and stay well clear of the local girls
