The main benefits of using a rebreather include no bubbles and reduced noise levels so you get closer to marine life, longer no-stop decompression dive times, reduced dehydration as the gas breathed is moist and improved safety with a reduced risk of decompression sickness.
You can dive on a rebreather for between 2-3 hours, and your dive time whilst using a rebreather is limited by the scrubber duration. Rebreathers are a closed-circuit breathing apparatus for scuba diving as an alternative to a scuba tank and apparatus.
A drysuit should be a snug fit with room for insulation undergarments under it so you can still move freely when you’re wearing it. You should not experience too much restriction on movement with layering under the drysuit, as this would indicate the drysuit is too tight. But if there is no resistance to movement, the drysuit may not be tight enough.
When you consider any guide to choice of wetsuit and water temperature, you must consider your own personal tolerance to the cold. In addition to how easily you feel the cold, also consider the topside conditions between dives on your dive interval. But also take account of the depth of your dive too.
The Sublue Mix Pro Underwater Scooter pulls divers or snorkelers along using two electric-powered propellers. The battery life of the Mix Pro’s removable lithium-ion battery life is the same as that of the WhiteShark, which is claimed as 60 minutes per 2-hour charge. With an amazing maximum depth rating of 40 meters (131 feet). Plus it has a smartphone mount too!
BCD in scuba diving is: B For Buoyancy; C for Control; and D for Device What does BCD stand for in scuba diving? A buoyancy control device is also known as a BCD, which stands for: The best way to do more diving and use your BCD more, is to book yourself on a scuba […]
Buddy Commando Profile BCD that has lasted for nearly 30 years without breakage or failure. It was only in the 29th year when diving in Barbados that the shoulder clips broke. This happened when donning the BCD which was attached to a 15 litre dive tank.
The main difference between a wetsuit and a drysuit is that in a wet suit you get wet, whereas a drysuit keeps you dry. Other differences include; drysuits are designed to be used in colder waters and tend to be more expensive than wet suits. Plus a drysuit can also be used for buoyancy control instead of using your buoyant control device, whereas a wet suit can’t.
If you’ve looking for the quick answer to; “does a drysuit keep you dry“, the answer is yes, but there are exceptions to this. Please read the rest of the article to find out more.
When it comes to scuba diving safety, a surface marker buoy is an essential piece of scuba diving equipment. A surface marker buoy (SMB or a Blob) remains on the surface for the duration of the dive, which is connected by a nylon line to a reel the diver holds. The surface marker indicates the diver’s position to the dive boat skipper at the surface, whilst the diver is underwater. Surface marker buoys are particularly used for safety during drift diving.
Underwater dive torches form an important part of your scuba diving equipment. A dive torch isn’t only for night diving or cage dives either. But rather it’s recommended to take an underwater torch on all dives. As you go deeper beneath the water’s surface the colours around you will disappear. Having a torch will help you to see the real colours and to illuminate your way in the dark.
A delayed surface marker buoy (DSMB), is similar to a surface marker buoy except that it’s deployed at the end of your dive vs used for the duration of the dive. A DSMB, which is also known as a decompression buoy or a deco buoy, are often used for safe diving ascents from depth on decompression stop dives. They are also used to indicate a diver’s position on ascent. This helps the dive boat skipper spot divers on the surface, especially in seas with a big swell.
