Whilst diving, I've always tired to breath slowly and relatively deeply, perhaps 4 to 5 dec breath in, and 6 to 7 sec breath out, using my diaphram as much as possible to get the best air exchange and CO2 flushing. My SAC tends to sit between 11 and 13 l/min depending on circumstance. However...

I was in the training pool yesterday, thanks to C19 it's one of the first times i've been back in the pool for a while, and i launched a dSMB from neutral bouyancy at only around 2.5m depth, and frankly, it was messy and fell really hard maintaining my buoyancy! Certainly it would be "no...

"Meet 'The Coral Guardian', a drowned deep-sea diver who is given another chance at life and a new home. A compelling story about the changing underwater world and the precarious connection between man and nature to celebrate World Oceans Day 2021." Stunning to watch in HD, with a strong...

Question: Is there any established rules or thumb of formula's for the loss of human body volume vs depth (compressive pressure)?? I believe in freediving one weights for the max depth to which you are dropping (so persumably one has to swim down harder to start with when you are going...

I have no experience of proper tecnical diving (yet ;-) ) and i was wondering what is the method that current dive computers work with a pre-planned dive? Ie, lets say you plan a dive on some suitable software (MultiDeco or similar) with times and depths. Is that plan (and deco model!) then...

I have just finished reading the excellent book "Deco for divers" by Mark Powell, and also reading a fair amouint of recent info on the controversy around deeps stops and trying to find an optimum ascent profile etc On thing that really stuck with me is: Draw a square (of any size) now draw a...

My club pool meets are back on from the start of June :-) Hurray, it feels like a long time away. Annoyingly i had started but not finished my SSI drysuit and Nitrox courses when lockdown struck, so i've been caught in a sort of no-mans land since then with regards to certs, and i really missed...

Just thought i'd say "hello" to SB! I'm both new and old to diving, having recently restarted diving after a long dry interval (20 years!) having originally dived at University back when they basically strapped a tank on your back, pushed you in and shouted "now try not to drown on us old chap"...

Ok, one of those "how long is a piece of string" type questions where there is probably no right/wrong but lots of shades of grey, type questions. For cold water diving i was planning in using a full face mask (usual caveats apply, this is not a thread about FFM vs halfmask+reg btw!!) and for...
