Answer	—	A: Where in the world do you need a cave diving certification to dive? Straight up the Answer is almost certainly NO, since unless there is some way of restricting access to a site, any person can put on dive gear and go dive without any experience/training. I am not aware of any countries with laws prohibiting scuba diving in any form except for reward (commercial gain... (more)	—	almost 6 years ago
Answer	—	A: Why didn’t Yuri Lipski inflate his BCD? It is always difficult commenting on what exactly happened and what was going through someone's mind. And in the end it is speculation. There is a good chance that he was overloaded and as he descended he started to panic which causes many physical and psychological changes such as perceptual narrow... (more)	—	about 6 years ago
Answer	—	A: Scuba diving right after passing certification I can tell you that no liveaboard operator will go on trips where they do not provide for diving opportunities for people on entry and advanced levels. All dives will be with a buddy and most likely there will be a divemaster familiar with the areas you will be diving to assist you with any issues... (more)	—	over 6 years ago
Answer	—	A: Does a diver's breath rate become slower when going deeper? Your breathing rate is not affected, although experienced divers always try and breath slow, deep and continuous, to conserve air and keep airways open. The higher partial pressure of gasses does however have many other effect on the body, including gas narcosis, oxygen poisoning and increased risk ... (more)	—	about 8 years ago
Answer	—	A: When taking a Go Pro scuba diving, how would you mount it? There are different ways depending on how you swim, take photo/film, etc. A head mounted approach is easiest and shows people your POV (point of view), bubbles can be an issue depending on your reg and swimming position. But greater risk in losing it of your head. Some people hard mount it on a plas... (more)	—	over 8 years ago
Answer	—	A: How to transport diving knives / shears? very simple answer: On a plane, always check them into the hold; Everywhere else, keep them in your dive bag until you need to strap it on before diving, after the dive take it off and place back in your dive bag. (more)	—	over 8 years ago
Answer	—	A: What wetsuit thickness is recommended in which temperatures for diving? Wet suit thickness is a very personal thing. I for instance dive in a 3mm shorty in 15C and higher and 3mm one piece for temperatures under 15C and above 6C Remember that you can also layer. So I would say a Dry Suit with thick under garment or a 7mm wet suit with a 3mm chicken vest underneath. Some... (more)	—	over 8 years ago
Answer	—	A: Diving mask colouring Black silicon blocks out all light except that which comes in through the lenses of the mask, leading to less light from peripheral. Spear fishermen, technical divers, free divers tend to prefer this. Clear silicon tends to discolour especially when stored with black rubber. But as far as true visi... (more)	—	almost 9 years ago
Answer	—	A: What will the water temperature be at Sharm el-Sheikh at a depth of 30m in October? A good estimation is to deduct 5 degrees Celsius from surface temperature to get temperature at 20m - 30m depth. (This is based on my experience over thousands of dives, but most of the diving is in temperate and colder waters) There are several factors that can influence the difference between the...

Answer	—	A: I've been out of the water for a little over a year; what should I focus on refreshing before I dive again? Diving is first and foremost a PRACTICAL skill so the best way to practise is to do it. Yes you can read through the books to refresh your theory, but this will not refresh your ability to dive. But it can be helpful in reminding you about small things you may have forgotten. Practising hand signal... (more)	—	almost 9 years ago
Answer	—	A: How many lumens for a diving torch? This is not an easy question to answer. More lumens means better light, normally also further range. But if you dive in areas with lots of suspended particles in the water you will get a lot of back scatter which in effect impacts on visibility. Then the next question is do you need it for night div... (more)	—	almost 9 years ago
Answer	—	A: Is this "dry suit cutting wrists" story realistic? I shall have to call bullshit on this. I personally forgot to hook up my dry suit inflation hose many years ago and sank to 36m (4.6 atm) in cold UK waters. Where I suffered from serious love bites (dry suit squeeze). Luckily my buddy figured out what I was trying to imply and attached my hose for me... (more)	—	almost 10 years ago
Answer	—	A: If my depth varies +- 2m when breathing in and out, what's going wrong? Firstly, it's very nice to see someone do the eye float thing :) But this should be done on an near empty cylinder (50 bar). Else you are perfectly weighted with about 2kg of air in your cylinder (single cylinger) and at the end of your dive you are 2kg lighter, and therefore might struggle with safe...

Answer	—	A: Does "dive your deepest dive first" still apply when using a computer? There are many discussions going on around this. Just remember the decompression models are theoretical mathematical models, backed by practical dives/research. We implement some rules for safety, like slower ascend rates, deep stops, safety stops, deep dives first, etc. Remember many factors dete... (more)	—	almost 10 years ago
Answer	—	A: Divers deliberately breathing fast before diving into water For scuba diving this practice has no use. as you will be under water for a while and will be breathing compressed air from your cylinder. In the old days people used this for free diving / skin diving /snorkeling to be able to hold breath for longer. I do not want to go into long discussions why th... (more)	—	almost 10 years ago
Answer	—	A: Surfacing rapidly after a Scuba Dive Here is an interesting article on wikipedia to give overview of pressure related injuries. Dysbarism Embolism in diving would most likely refer to Arterial Gas Embolism (AGE) and the internet is full of articales on AGE, DCS, Baurotrauma etc. But to give you a quick laymen overview of the issues r...

Answer	—	A: When describing my PADI qualifications with a CMAS diver, is there a well know equivalence table? The easiest way to compare diving qualifications is to look at the ISO standards: International Standards The International Organization for Standardization has approved six recreational diving standards that may be implemented worldwide (January 2007). The listed standards developed by the (Unite... (more)	—	over 10 years ago
Answer	—	A: During a safety stop, how do I avoid my feet floating up? Ankle weights may only be a solution for beginner divers. The fact that your feet may be floating is not a real problem, the problem is when your whole leg floats as this causes a feet up head down profile which is bad. (Especially when diving in a dry suit) To get your feet down get yourself a pa... (more)	—	over 10 years ago
Answer	—	A: What exercises can you do before Scuba Diving to improve your air consumption? Personally I would say regular exercise routine with swimming and cardio will help improve your air consumption. But the best exercise for scuba diving is more scuba diving. The more you dive, the more comfortable you will be and the more efficient your movements become underwater the lower your br... (more)	—	over 10 years ago
Answer	—	A: Eating in a long sport activity (scuba diving) to keep your strength up That is extremely long dive that come with many potential problems. Hydration Nitrogen Build-up Hypothermia Nutrition Exhaustion Hydration can be solved with soft bottles to drink from, camel backs might work well. Nutrition you could look at liquid meals; corn starch syrup, soup, meal replacement s... (more)	—	over 10 years ago
