Scuba Accessories
Aside from the basics such as air tanks and masks, there are a host of scuba accessories that can make the diving experience that much more enjoyable. Wetsuits, for instance, while not “necessary” can help keep your body warm while under the water for extended periods of time. In colder water, dry suits are often recommended.
Drying racks are often mentioned as worthwhile scuba accessories. These racks are designed to hold all of your diving gear while they are rinsed off after a dive. After a rinse, the rack should be moved out of direct sunlight to allow the equipment to dry.
Scuba knives are often recommended scuba accessories. They can be quite useful when exploring underwater. They can also be a great safety device under certain circumstances.
