Spearfishing Safety

The decision to sustainably harvest marine life can spark vigorous discussions among divers. Regardless of your views, there are benefits to understanding the equipment, procedures, and dangers associated with spearfishing.

There is no catch and release when spearfishing.

Shark Deterrents

Many divers seek interactions with sharks, but others actively seek to avoid them. As long as sharks are in the water, people will look for ways to reduce the lethality of a shark bite or decrease encounters altogether.

Understanding Oxygen Kit Components

Oxygen is the standard of care for first aid in dive injuries. You do not need to determine if the injured person is experiencing decompression sickness (DCS), arterial gas embolism […]

Used Rebreather Scrubber Disposal

Sorb, or scrubber, plays a critical role in rebreather diving, as it is responsible for removing carbon dioxide (CO2) from the diver’s breathing gas. Small granules or pellets absorb exhaled […]

Keamanan Silinder

Pengguna harus mengoperasikan silinder dalam parameter desain, seperti mengisi hanya pada tekanan servis terukur dan memiliki silinder yang diperiksa oleh teknisi yang terlatih dan berkualifikasi secara formal dan memenuhi syarat oleh fasilitas pengujian yang memiliki reputasi baik dan diakui. Lebih dari 90 persen kerusakan terjadi selama pengisian, sehingga pemeriksaan yang rajin selama proses ini sangat penting. Silinder harus beroperasi dengan aman selama masa pakai jika pengguna mematuhi desain dan kondisi pengoperasian.

Minimizing Lift Bag Risks

Divers generally use lift bags to raise submerged objects to the surface. The lift bag is filled with gas until the object exhibits neutral buoyancy so divers can bring it to the surface with minimal exertion.

Pillow bags are the largest lift bags and require significantly more gas than the other styles.

Pelindung Tangan

Sarung tangan adalah salah satu peralatan menyelam yang paling sering diabaikan dan bersifat individual. Saat memilih sarung tangan, pertimbangkan jenis penyelaman yang Anda rencanakan dan apa yang Anda harapkan dari pelindung tangan Anda. Saat memilih sarung tangan, pertimbangkan faktor-faktor berikut: perlindungan termal, kesesuaian, ketangkasan, perlindungan dari bahaya, ketahanan terhadap benturan, dan bahan.

Diver Recall Systems

Whether for recreation, research, or commercial work, diving puts humans in a fundamentally hazardous environment. Visibility, pressure effects, and sound distortion limit communication between divers and surface teams, making real-time […]

Air and a Spare

No matter which alternate air source you choose, learn to calculate your air consumption and regularly practice emergency procedures. There are many ways to configure each type of redundant breathing-gas supply, but make sure your setup matches your training, gear arrangement and dive objectives. If a naysayer thinks your equipment choice is unnecessary, let them know that the difference between a fatal accident and an embarrassing incident could come down to a breath or two. Any redundancy is better than none.

Composite Scuba Cylinders

Composite, fiber-wound cylinders are making their way back into diving in rebreathers and other advanced scuba gear. The weight and lifespan benefits of these cylinders are attempting to challenge their previous cost barrier.
