Scuba diving in the tropics

[underwearphil]

It is some years since I did any scuba diving in the Red Sea. Always had a wetsuit. Once you get below about 30 feet, the water gets cool, it is only the surface layer that is warm. It is not as good idea to risk muscular cramps in cool water when deep diving. Agree with other posts that wetsuits also protect against jellyfish stings (some of the tentacles can be metres long!), puffer fish toxic spines and abrasions from coral.
More recently, have done snorkelling in Maldives and Mauritius, just going down to about 20 feet. I am happy to just wear brief speedos or similar (but still need to look out for dangers!)
I started my scuba diving around the coast of the UK. Thick wetsuits essential! Was diving on wrecks, going down to about 120 feet. There the water was only 4 degrees Celcius.
Unfortunately, my ears are not up to deep scuba diving now. I miss it. I must just stay near the surface, in my speedos.
