Scuba diving in the tropics

[Lap Counter]

There are 2 types of SCUBA divers:
- those who admit they've peed in their wetsuit
- damned liars

In really warm tropical water, divers will sometimes opt for a full body Lycra suit (similar to a unitard) but a thin (3mm) neoprene wetsuit is usually necessary to avoid getting chilled. The ocean acts like a giant heat sink, sucking the warmth out of your body.

The wetsuit also protects your body from chafing caused by your BC (buoyancy compensator) weight belt, and whatever else you've strapped to your body like dive knives, etc.
