Guys, thanks for taking the time to reply and giving me some comprehensive feedback.
I light of the above, I think I will avoid diving in SZ. For me it seemed like a convenient way to get some time in, but after reading this I will be avoiding!
Think I will put the cash towards some gear, and get out to the philippines for a week.
Do you have any experience with diving in Zhuhai? As this was mentioned last time I was in HK
I have heard there is an island off Zhuhai that offers diving,

I am just skeptical to try anywhere as it is a regular occurrence for Chinese beach's to advertise pictures of beaches from the Philippines or Thailand, claiming that they are beaches in China. I just have never heard of anybody saying anything good about a dive in China, usually its restricted to certain areas and there just isnt a lot of fish in the sea here as everybody ate them, thats why you see chinese fishing vessels everywhere in the world. If you are really itching for a dive, Hong Kong is it, or the Pedro Blanco dive in Shenzhen, its expensive, a 2 hour uncomfortable boat ride (small boat with 8 divers, two crew, and a couple of dive guides, to a pinnacle that stands out of the water, that probably used to have good sea life, but it has been fished, spear fished, dynamite fished, and more. But you can still see some smaller tuna and about 10 meter vis, from what i have heard who friends who tried it a few times, as they advertise it as an underwater miracle with all kinds of life, including whale sharks.
I think you got the idea, fly to manila or cebu and make it a long weekend. Malapascua (although a 3 hour drive and 30 minute boat from the airport) was fantastic. Thresher Sharks, Mantas, Devil Rays, Whitetips, Corals, Macro, all within close proximity to the island. Its more about the time than the cost, you can fly round trip from Hong Kong to cebu for like 200usd roundtrip with all taxes included on Cebu Pacific or AirPhilExpress, and the dives are a fraction of the cost they are in Shenzhen.
