Yes I'm aware. To name a few, deco, minimum gas, your lost gas, team lost gas, working phases of the dive, flow, scooters, stages and I could go on... But I over simplified for a forum, my bad. A turn pressure is a turn pressure. Turn pressures should be calculated before hand. The MOD...

Thirds is thirds is thirds. I think the metric system is inherently better for most things, but, as many have said, use what you're comfortable with. I'll dive M, you'll dive feet. I'll calculate gas in free litres and bar, you'll calculate in PSI and cuft (somehow...) Everything will be...

My point precisely. It's a very good, amazing system Id love to do. But someone asked the limitations, I just showed them. Sent from my iPhone using Tapatalk

I must admit, I don't have experience of single file, no-vis, touch contact procedures. I'm not GUE cave trained. I'd like to be, but round me all the caves aren't conversant with GUEs standards. They are conversant with sidemount, zero-vis, solo diving techniques. Top guys within GUE...

If I dived my doubles rig with an RB80 diver, am I expected to be fully conversant in how to help them with any problem? Fully familiar with their gear? I'm not. It's not a standard. You have normal GUE hog rig which is standard. SCR GUE rig which is standard. Then there's GUE divers diving...

My point wasn't just about gear. In no mount, zero-vis caves, all team diving protocols go to hell. This is my point about the philosophy, keep it simple, redundant and safe. Entering a no mount, zero-vis cave with another diver, no matter what the gear, and trying to dive with them in...

I did say closest thing to panic as panic in my eyes are ineffectual actions. Doing that was ineffectual when faced with a much bigger problem. Sent from my iPhone using Tapatalk

You can't have 3 different set ups (doubles, RB80, JJ) and define them all as standard. There might be standards for them, but they're different standards. "The central concept breaks down, and therefore standardisation may not be as useful" is a much better worded version of my post. The...

So the RB80 is standardised? Sent from my iPhone using Tapatalk

They don't. But they don't tell you to dive sidemount either. It's not the standardised kit, hence, the limitations of standardisation, which is the topic of this thread. Sent from my iPhone using Tapatalk

My third cave dive, I'm alone, 60 minutes of hard dry caving from the surface, then 3 sumps beyond the end of that. I was squeezing through a 8 inch high gap by shovelling grit out the way with the top of my head/side of my face. BAM, ripped the diaphragm on my second stage, next breath was...

There's a whole subsections of diving where GUE don't apply well at all. The two that spring to mind are both cave diving. Put your elbow on your desk, raise your forearm vertically, make a fist. Imagine a passage this high, for a few hundred metres, with zero vis from the start, line traps...

The oldest diving club in the world. Cave Diving Group. Established 1947... It's worth noting BSAC don't teach cave diving also, leaving it to CDG as no agency really gears towards cave diving in Britain. Sent from my iPhone using Tapatalk

It's not bad TIL you need a gauge reader! Sent from my iPhone using Tapatalk

There are plenty of sump divers who dive expecting nothing but full blackout conditions on every dive. It depends whether you're diving to go somewhere or diving to dive. Also what you're used to. I dream of 15feet! A lot of the time I dream of being able to see my gauges without a special...

I have an xdeep. I like it lots. It won't connect to my computer currently, but its probably something I'm doing wrong. I shall have another play with it before bothering Xdeep. Otherwise, zero complaints. I mostly cave dive, my favourite feature is it sits half way on my right arm. In...

It's only a safety feature if it's necessary. It's not necessary, so it's a complication. Though it has misguidedly been attributed to safety. If it makes you happy and doesn't hurt anyone, including you, go for it! I wouldn't have glitter personally as it would be a nightmare with the lights...

The burst disk is not a safety valve, it's an unnecessary complication implemented almost solely in the USA, the rest of the world dive just fine without them. Colourful gear looks better in photos, makes you more visible and is easier to tell apart. I'd get a glittering rainbow wing if I were...

Just as a note, most European divers don't have any burst discs. Sent from my iPhone using Tapatalk
