I've always had a problem getting out of thicker wetsuits (4/3 mm and above, chestzip with/without hoodies). I would like advice from anyone who has tips getting out of these types of thick wetsuit...
I'm soon to embark on a chilly scuba dive around 5-7C at 18m, of which we'll be wearing 7mm semi-drys with shorties. The next thickest I think is actually a drysuit for really cold waters, but not ...
I'm taking a Go Pro to shoot some diving video, and I've never done this before. Assuming a mask mount is not an option, would you strap it to your wrist, attach it to your BC, or take it loose / o...
I've done a few scuba dives and really enjoy it, except (diving or not) I get cold quickly when submerged. I have very low body fat and relatively low blood pressure (though I am healthy overall) ...
I am considering getting a used wet suit for sailing and canoeing in the early spring and next fall. What should I look for? Based on the related Q&A below, it looks like I will want 6-7mm (1...
Have heard great things about diving in the Red Sea. However, Egypt's not the most stable and safe place to visit. What are the alternative locations for diving in the European side of the Medit...
This question is based on my desire to avoid disturbing, injuring, or scaring away an octopus which is camouflaged to look like a coral reef. Since it's so difficult to see, I'd like to know how to...
I'm looking at buying regulators for scuba-diving this weekend and we came across the options to have a DIN or a yoke valve for our first stage. What are the pros and cons of both a DIN and a yoke ...
I've picked up a surplus used aircrew Beaufort Mk 10 Immersion Suit (for aviation use, but I think there's more likely knowledge among watersports enthusiasts). It needs latex socks adding to the b...
On longer dives, let's say over an hour long, the air from the cylinder becomes rather dry and can cause a dry throat - what are possible ways to have a drink when scuba diving? Are there alternati...
Firstly a preface: all training's good and especially overhead training where the environment's so unforgiving. Plus lots of practice. Where around the world are dive locations where you must ha...
If I am required to transport my diving equipment (in the UK and Abroad) what are the best practices of transporting my diving knife / shears? If on a plane this can just go in the hold luggage sa...
No decompression diving (No stop diving) refers to "diving that you can always ascend directly to the surface without stopping, yet without significant risk of decompression sickness" (according to...
I saw the footage of the fatal diving accident of Yuri Lipski. One thing I wonder is what really happened. He doesn’t seem to try to inflate his Buoyancy Control Device (BCD) to get back up. Did ...
Out of all my dive gear, the item that is the hardest to dry is the BCD. If the weather is nice then it is not an issue, just put it outside. The issue is drying my BCD when the weather is rather i...
In a couple of weeks my buddy (husband) and I will be doing a few dives on the UK's Jurassic coastline, in Swanage. It's said if the vis (visibility) is good here you can often see seahorses, as t...
My brother and I are planning to get PADI, (Professional Association of Diving Instructors), certified. The e-learning course in July, 2018 is $180, which isn't super cheap. Can I buy one and re-us...
Is there any special equipment needed for diving with Nitrox(more than 21% O2)? In Germany there are regulations and laws that say that you can only dive using Nitrox if you have this special equip...
I'm looking to go scuba diving at the Great Barrier Reef next year. I've not yet been certified, but I plan to do it soon. If my only scuba experience is the certification course, do I need to wor...
My husband and I are learning to Scuba dive this year with a friend. We're doing the SSI courses, which require a large number of dives to progress through each qualification. Open Water through to...
My husband and I scuba dive together often, and he really wants to get the chance to scuba dive with cuttlefish (and why not they are super cute!). This can involve night diving. What dive sites a...
Is there a relative scale to which one can estimate the size of a shark by looking at its dorsal fin? I know it will differ from species to species, but is there a general guideline maybe for each...
You can easily find the temperatures at the surface of the sea. However, to choose the correct diving suit, I would like to know the temperatures that can be expected at a depth of about 30 meters...
This is something I have been thinking about since answering this question about guessing the size of a shark. What precautions would a scuba diver take or is this something that is simply avoided?
For diving in the UK in colder weather the water temperature can easily be below 10C. Warm water regulators seem to be 10C +, and then cold water regulators for below that as they need to be able t...
When scuba diving I use a weight belt for my weight system - my BCD does have an integrated weight system, but I am still working on my weight distribution for trim, and total amount for buoyancy. ...
I have been an avid diver for over a decade. Once upon a time, I wanted to get my divemaster certification in order to work (for a short time) as a divemaster. However, that ship has since sailed, ...
When a diver goes deeper, the air goes into the lung is compressed, compared to the state of air at sea-level ground. Accordingly, the oxygen partial pressure is higher than the ground. If a diver ...
I'm having what seems to be an unusual problem. After equalizing, it seems like my mask is filling with air and starts to pull away from my face and fill with water. I can press it back on my face ...
This week, when diving mostly with people more experienced than myself, I noticed something about my buoyancy compared to theirs. I'm wondering how to fix it. Before setting off, we all selected w...
I'm fascinated by corals. I've been told there are more than a thousand varieties spread out in bodies of water throughout the world. What part of the world has the most varieties of corals in a c...
I've been scuba diving for several years, but it's been a little while now since the last time. I last dove in the summer of 2014, and I'm traveling to Chile next month and am hoping to go diving t...
It has been a number of months since I last went scuba diving - short enough that I can still remember everything, but long enough for any diving specific exercise related things to have worn off. ...
Title says it all really. I am looking to buy a diving torch as I am taking up diving next year. What am I looking for? They seem to range from 100lm to 2500lm. Realistically how many lumens are ...
We're planning a 9 to 10 hour dive. We can't go that long without eating. What kind of 'food' could replace at least 2 meals of the day so we can 'survive' a long dive like that? We'll figure out...
Because they rely on radio signals, GPS units generally do not work underground or underwater, but what about a plain ol' magnetic compass? Are the magnetic fields of earth present at all depths? ...
In a similar manner to this question: When describing my PADI qualifications with a CMAS diver, is there a well know equivalence table? How do the PADI qualifications match up to the SSI ones? Is t...
In order to configure my Aladin diving computer, I built the interface as described here. The software "DataTalk" can be used to configure the diving computer. However, the Windows version (which c...
I'm learning to dive and the first purchase is a mask and snorkel. The issue I have is discerning what mask to get colour-wise. There seem to be two main types for the silicon, clear and black. The...
I recently read over this post: What to consider when buying fins for recreational snorkeling and found some great advice in what to look for when purchasing fins for snorkelling. However I was wo...
On my last couple of dives, I've noticed that my feet tend to float up during the 5m / 3 minute safety stop. It seems to be more of an issue when doing a safety stop using a line to ascend, but I'v...
I'm reading a very good novel, called "Smilla's sense of snow". A minor figure tells this story from the time he was a frogman with the marines: Going down, I glide through a cold belt [...] I...
When doing my PADI open water course, including all the stuff around pressure groups and calculating maximum depth times by hand, I was told that I should always do my deepest dive first, and go sh...
I recently had my first scuba dive. And the other instructor here was referring to something that is related to air Embolism as I overheard, that one should not surface too rapidly after a deep div...
I'm currently in a French overseas territory, and almost all of the dive centres and clubs here use the CMAS system. Whenever I've booked in for a dive, the dive centre has looked at my PADI qualif...
