Comfort
Your wetsuit is an environment all its own. It keeps you at safe temperatures in many types of water. Specific types of wetsuits are best for particular temperatures, however, and having the right one is vital.
Utility
Masks help you see without irritating your eyes. Gloves protect your hands from sharp rocks and harsh sand or gravel. Scuba booties or fins propel you through the water with ease. Weight belts help you stay submerged. Snorkels let you skim the water surface and look below without needing a heavy air tank.
Life Support
Scuba tanks are usually made of aluminum or steel. Aluminum is lightweight and avoids rust. However, steel is more durable as long as you protect it from corrosion.
Navigation
Underwater navigation requires waterproof and pressure-proof devices such as compasses or even GPS.
Protection
Spear guns protect you from dangerous predators like sharks. Another more advanced repellent is the SharkPOD that puts up an electrical barrier.
