Divers participate in many specialty activities that enhance their enjoyment of the sport, and specialty courses are available to prepare you for just about any environment or activity. Examples include:

• Photography and Video
• Hunting and collecting
• Search and recovery
• Night diving
• Deep diving
• Wreck diving (external survey)
• Underwater environmentalist

Certification in these activities is not required for you to participate in them, but formal training will increase your success and enjoyment. A great way to learn many of these activities is to enroll in an advanced scuba diver course, which teaches you deep diving, night diving, and several other specialties.
