Well of course you wouldn't. I'm saying that other than signals and noise, that's your only real option for reigning someone like that in. And by that I mean it's a non-option.

Tomberforce posted:Unrelated - as a PADI DM, do you guys think that there would be alot to be gained from taking the GUE fundamentals course? I'm pretty interested, but it's hard to find a GUE instructor in Perth where I live. I help out on IANTD/NOB Tek light courses. I know the instructor and I am doing my IANTD DM course. We had an GUE Cave diver doing an cross course for NOB Nitrox adv. funny I know but he just wanted to do it and be in line with his dive buddy's. Anyway, I had to check his skills and be his buddy. See how he dived. The way he did do the dive, and the signals the deco stops and using the stage botle. And being freaking flat not moving at all was pritty amazing to see. In the end he and my instructor where reviewing me  It was for him also nice to see I could be flat stable and doing my deco stops good. I think GUE is the best you can get there is not a bad instructor within GUE at this time. For all the other organisations they are good but you need to find out if the instructors are still good.

I am afraid you are going to be right on that one. I would go for him probably. If he is not going into the deep. Just because I was like him once. I can't remember not having decó dives on my holidays. We just did them. We always respected the computer. I did dived to 55m on air, and I once was at 30m with 30bars left. etc etc. Why, because why not.....that's what I thought at that time. Now, I know better. I am certified to do deco dives, and deep dives on air. I made dive tables electronic with all kinds of deco maths in it. Now I know what is behind it. And the funny thing is we never go deep anymore with deep I mean we go like 35m. max or so. But usual 20m. We do a good planning before we enter wrecks what we never did. Knowledge comes with age I think.

LOL I think with the physics involved anything fast and small enough to travel through the water quickly and with range would also hurt really bad. A speargun has actually saved someones life before. Two guys were spearfishing and instead of doing 1 up 1 down dives they were doing 0 up 2 down which is dumb. So as they are both heading up after a deep dive and one of them looks away for a little bit, then he looks back over towards his buddy only to find him 25 feet down and unconscious. Having just finished a dive, there was no way he was making it to 25 to get his buddy. So he dove down a little bit and took a well places shot into the guys plastic fin. Hauled him up like a fish and woke him up. I also went diving this weekend. Dove a bunch of different wrecks in 70' mostly broken down old wooden ones but a few really cool tugs and stuff. Also got various dinners for the next week. Checking out the pilot house on a tug freediving was really cool, I can imagine why penetrating wrecks is so fun.

I'm in a bit of certification limbo with wrecks now. Technically I haven't done the wreck speciality - but this weekend I DM'd on the course, and sat in on all the theory sessions, so I've done everything and got the experience - but I haven't paid PADI $500 and so haven't got the C-card. I guess it's not going to make any material difference to my diving, but it'd be nice to know whether that experience would count if I wanted to do an advanced wreck course in the future, as I think I might. I'd rather not pay so much extra money to get experience I've already got!

The main difference is a lot of wrecks are well out into the ocean, so you also have to deal with unpredictable current, hot drops, launching surface markers, drifting decompression, etc. And on that note I'm doing the PADI Cavern class with Rockcity this weekend!

Finch! posted:I tried wet face and dry face - no tangible difference. I also cooled my face as much as I can with ~29 degree Celcius water, to no avail. I don't like that mask anyway I get this problem too, but a friend showed me how to fix this. Just use a generous amount of saliva and then wash it off by splashing the mask as briefly as possible in the water. It took a few attempts, but now this technique consistently eliminates my fogging problems. Sometimes I get a little fog on the edges still

Okay, I've tried rigging my speargun. I haven't crimped things together yet, let's check it out Here's the loaded spear, the crimp and loop don't appear to be interfering with the loading mechanism. Nice and easy to attach/detach the spear into the gun  There's a tab here for keeping the line tucked away. Cool  Here's the line wrapped around the tab at the front of the gun  Here I wasn't quite sure whether I should wrap the line above or below tab before wrapping it around the line release. Leaving the line above the tab and then wrapping over the line release like this, and then bringing the line below the tab seemed to be the tidiest configuration, so that's what I went with. Seem good?  And then I brought the line back up to the bungee.  In this setup I have everything under some tension, which makes it difficult (but not impossible) to wrap the line around the line release. Does this look approximately correct? This is my first time rigging a speargun, so I'd really like to learn how to do it correctly. If everything looks about right then I'll crimp it and take it into the water next weekend to practice loading The gun also came with these things:  What are these? It came with 4 crimps and 2 of these little plastic loops, so since I only need 2 crimps I'm guessing I may need 1 of the plastic loops somewhere and the other is an extra?

Bishop posted:I said non-lethal, not painless! Solid advice Bishop, cheers. I wish I lived in a location where I could get cave training - the nearest is in South Australia, so about 1500 miles away! I also think that I consciously experienced narcosis for the first time this weekend. At about 28 metres I was aware that my teeth felt numb - and at 31 metres I tried to test myself by transferring my torch lanyard from one wrist to the other and felt...weird. It was still fine and I was still very situationally aware, just concious that things didn't feel quite normal. I've been to that depth before and not felt a thing, but I was feeling a bit seasick just before the dive, I don't know if that contributed to it. I went down to 28 metres penetrating again the next day and felt fine. I was diving 32 mix Nitrox on both dives.

They were all super helpful and supportive. I'm really pleased with my air consumption on my second day of diving, I came up with 1100psi on both dives, as opposed to 400psi on both on the first dive (I was regularly communicating my air supply to my instructor so I don't consider that an overly bad thing in this case). Buoyancy still needs work, but at least I'm getting a bit better with trim.

What sort of briefing (and, no, yelling at them afterwards on the boat does not count as a 'briefing') should the instructor have done to prevent the problem? Yeah that was from a situation on our boat last weekend - the DM (not instructor) in question wasn't leading the dive, she was just on the boat fun diving and paired with the guy, who was apparently experienced and 'dived on the wreck all the time' as an 'insta-buddy'. If anything it was him leading the dive. She had no reason to believe that he wasn't competent and as it was not a formal guiding situation she didn't undertake a formal briefing (quite reasonably imo). It only became apparent that he didn't know what he was doing during the dive, at which point she tried to get him to ascend safely, but he ignored her. Fundamentally that situation arose from the diver in question lacking even a rudimentary understanding of decompression obligations, and as such leading to a dangerous situation for both him and his buddy. I absolutely agree with you that theoretical knowledge is meaningless unless it's effectively translated into diving - but having a thorough grounding in diving physics and physiology doesn't at all detract from your practical in water ability, and can help you anticipate and respond to dangerous situations as or before they arise - which to my mind is the main role of a divemaster. I'll keep reading.

Bishop posted:Alright I thought about this post some more. I agree with the second sentence, but the first is poo poo.... Should I seriously just trust decompression tables because of magic? Should the concept of tissue compartments or whatever be taught only to hypobaric scientists? That's complete bullshit. I should know why and more importantly, how, all the nuances of decompression theory apply to me. Even basic open water divers should have a bit of a sense of how all of this works. Plus we were talking questions to stump DM candidates, who should absolutely know a fair amount of deco theory. That is what was on my mind also. I wanted to know the background of the diving tables. I mean how much tolerance is on them etc. So, I started to figure this out from the start with the Bulhmann formula's. I made an graphical presentation of this formula. You could put in your diving profile and it would show you the real decompression limits based on these formula's. It came for me more or less as a surprise that even the padi tables are very close to these deco formulas there is not much contingency. I thought when you were like just in deco from a table you were not in deco for real. But then I realized that you are always making a deco dive you are always accumulating nitrogen. So when you tables and or diving computer tells you you are in deco you must not think you are not because of some kind of build in safety. The 3min at 5m stop after each dive makes much more sense now also. Orions Lord fucked around with this message at 09:13 on Jan 22, 2013 |

Plus we were talking questions to stump DM candidates, who should absolutely know a fair amount of deco theory. Diving only happens in the water. Reading about stuff does make it work any differently. An engineer is not in any sense a better driver than someone who cannot change a tire. Some people think knowing some trivia about tissue compartments makes them know something about decompression, which then makes them a better dive. It does not make them a better diver, nor does it even helps them understand decompression; it merely lets them see the mathematical theory that built the tables. But the tables themselves are just lookup charts, and nothing more. Lots of divers fancy themselves better divers because they have a smattering of knowledge about diving trivia. Give me a DM who never breaks trim but cannot even use tables, over a DM who will just start talking (and never shut up) about really anything to do with diving. Actually the entire reason I never use DMs is just that: every DM thinks they have something useful to say, and never are particularly good divers, because they lose focus on the water. Their job is to role model; but the lesson most divers get from most DMs is that talking matters, and diving does not really.

pupdive posted:Diving only happens in the water. If you replaced DM with tech diver in that rant and i'd agree with you  We were just joking around on how to mess with DMC's. As part of curriculum they gotta learn some dive science and its fun to mess with them. As i take my DM'ing, i need to be able questions students answer. Basic dive theory, basic dive physiology, things that a student might worry about. Divemasters also need a bit of a bravado when teaching. It sucks when they don't turn it off outside of the classroom, but there its necessary to a degree. A lot of people are really anxious about diving, even if they are excited. They worry, freak out, and all in all, need someone who's a cocky know it all to give them a sense of comfort. If I DM a class and say nothing, just interact with the students on a necessary basis and be quiet, i'm not doing my job. If i'm talking up stories of dive trips, experiences i've had, things i've seen, students are much more likely to be confident in me. In turn, they become more confident in what they are about to do.

How long does the eLearning classroom component of PADI Open Water take generally? The site says 12-15 hours but I'm hoping that is a really high estimate. I'm considering trying to cram it in this weekend before we head to the resort on monday. My worry is I don't want to waste a huge chunk of time on vacation doing classroom work.

Well, Bishop and I managed to not die in the caves in Northern, FL and are now newly cavern certified. I also finished my advanced certification on the trip as well. I have to say, I enjoyed cavern diving more than I thought I would. I'm still not sure I want to go full on cave diving (especially my wallet isn't sure), but this was a pretty good way to dip my toes in the water. I'm also fairly impressed with the Pirahna Black Star light I picked up for my main light, it was plenty capable in the cavern and even in the early stages of the actual caves. I'm not sure how it would handle it if it got really kicked up, but it cut through some mild silt pretty well. I did however realize that I am terrible with a reel. The only time I've ever been good on one was one without a crank when carrying a drift buoy.
