Scuba diving equipment adapts you to the underwater world and makes you part of it. You do the diving, but your scuba gear makes it possible. That is, a mask doesn’t see for you, but allows you to see underwater. A dive regulator doesn’t breathe for you, but allows you to breathe underwater. A wetsuit doesn’t make heat, but allows a body to more effectively retain its own heat.
Browse this section to learn more about how to choose scuba gear that :
- is comfortable for you
- fits you well and looks good
- will be a long-term investment for the type of diving you plan to do.
The Gear You Need Depends on Where You Scuba Dive
You can dive almost anywhere there’s water. The gear you use will vary somewhat depending upon your diving environment, as well as your preferences. There are four general categories for dive equipment, but some gear fits in all the categories – for example the mask you use for tropical diving is probably for temperate or cold water diving, too.
- Tropical scuba equipment – Used when diving in warm (24ºC/75ºF and up), clear water.
- Temperate scuba equipment – Used when diving in moderate temperature (24ºC/75ºF) water.
- Cold water scuba equipment – Used when diving in water cooler than (15ºC/60ºF).
- Tec diving scuba equipment – Used by very experienced, highly trained divers to visit environments beyond the normal limits of recreational diving.
