I thought it was common folk knowledge that "Suunto RGBM" isn't actually RGBM - with the understanding that regular wrist computers aren't even close to being capable of running the full RGBM algorithm; that requires access to more serious computing power - but is instead a standard dissolved...

The "gradient factor" a diver is experiencing at any given point of a dive is just the maximum of the percentages of permissible supersaturation across all compartments at that point. A "Surf GF" is then easy to calculate at any point in time by calculating the ratio of supersaturation to the...

Good point, I have changed to use {A} - {B} - {C} on general role descriptions to avoid confusion, however I think it is implied from the original description ("Diver number 2 to pedal ahead following diver number 1") that #1 was indeed in front on the specific dive described in the original post.

This is something worth noting. In a team of three, cruising along normally in the order {A} (leading) - {B} - {C} (following), the main team responsibilities of {A} are basically 'make sure that "someone" is behind me (i.e. I can regularly see a relaxed passive light communication coming from...

Ultimately you have a choice/control over quite a lot of variables via the utilisation of option No.1. Firstly, you have the choice to dive or not dive with the people who would make up your team. Secondly, if you are on your way in on a dive and you encounter a line clusterf then you have the...

Oh yes. I'd happily dive with someone who is able to admit mistakes and who shows they want to learn from them before I'd dive with someone who wants to use other people's mistakes to build up their own ego.

Accident/near miss analysis can be done without hysteria and SHOUTING, and without fingerpointing and blame. We can all make mistakes, we can all make decisions under pressure that we wouldn't make otherwise, and we can all learn. I'm grateful to the OP for sharing his experience so we can all...

Thanks for posting - no roast intended here; we can all learn. Up to the point where you did the blind jump, I'd say the cause of the situation lies 90% with your "buddies" for rushing ahead without you, and 10% with you for rushing to try and keep up and distracting yourself with the camera...

You are right, I used DCI when I meant DCS. I've corrected my post.

A reasonable position might be; If you are physiologically normal, in reasonable condition, and avoid provocative behaviours, then, for square profiles even up to the point of saturation in 20ft or less, decompression sickness is unlikely. This is supported by theory and some actual...

Of course you need to think about contingencies, of course you need to adapt to the realities of the situation. Only internet blindness is making you think that anyone is suggesting anything different. But you do need a starting point to start to adapt from. All this is saying is, hey, for...

We're talking open water here. Nobody is questioning that overhead environments require different rules.

Wiggle of the jaw does it for me. I have to say I almost never consciously think about equalising any more, probably 90% of dives I don't need to use a hand to equalise even once.

Some of us dinosaurs are still tech diving OC around here

Actually there are at least a couple of options: Firstly, you could become a different species - apparently Guinea Pigs can happily do profiles that would result in unpleasant consequences for humans. Second option for going deeper and longer without incurring deco is to buy a submarine...

Whoooosh...

I will be very disappointed if this thread doesn't veer off topic to become a parade of people telling AJ he should get a CCR so he can start doing big-boy dives

My pleasure! Great to see people putting them to good use. Exactly that - if you have a wing without built in roll control bits and you tried to use a 'normal' backplate then you'd be strapping a flat surface (the spine of the backplate) to a convex surface (the tank), you only have contact...

Nicely done! Are the things through the bolt holes holding the wings in place?

If the gauges attached to the depth tags were able to have their profile downloaded afterwards (I'm picturing something like a 300+m capable Sensus Ultra here) then it seems to me they could give very useful additional verification even without needing to be super accurate. If you had a...
