The reason the forum was opt in years ago was because those that didn’t understand DIR and had questions were getting garbage answers. It wasn’t to protect the people that actually understand DIR. It was to try to allow those with questions to get accurate answers.
It doesn’t work though...
Same. My only GUE card is Tech 2. I was taught side mount cave from a GUE instructor before it was a course because I don’t care about a card. GUE isn’t nearly as rigid as the detractors want to make it out to be. Fundamentals only exists because too few students had the necessary basic...
GUE used to teach this and dropped it. It is a bad idea because you are more likely to clip off your light and forget to bring the cord back over the hose resulting in a trapped hose. This is a bigger problem than having the hose and cord slightly twisted if you forget to pass the cord under...
A halcyon flare on low gives you 5 hours. Plenty for most dives in Mexico. For really long dives you can carry two. While I hope a newer diver isn’t diving side mount it is trendy and handhelds are much cleaner for sidemount.
I haven’t dived all of the other canister options but would highly...
To further add to this. Prior to using DIR JJ used hogarthian in my original cave training manual. However that term became corrupted and was being used way more broadly than was intended by the founders of GUE. Not surprisingly the same thing happened to DIR and GUE basically dropped that as...
First, so what it is a bit if surface galvanic reaction. Unless it is deeper than the picture suggests just ignore it. There isn’t an aluminum bolt option and messing around with plastic washers just gives you something easier to break that isn’t really necessary. Second, throw away the back...
It really isn’t. It just takes the right foundation and mindset which as discussed to death here isn’t taught in OW anymore. My only formal Trimix class and only GUE class ever was tech-2. Trimix used to be a bit more self taught with mentors. I had already been doing the dives and JJ...
Sidemounting a stage doesn’t scale. Not how DIR works. You always breathe the outside bottle because it makes confirming the mix easier and safer. In a cave you drop them when not in use and in the ocean generally nose clip back to get out of the way once used.
It is strange how things...
Yes they have. It is still important to learn to conduct dives without them, particularly decompression ones. Computers are now more reliable than lights, so it is more about understanding where you should adjust despite what the computer is saying and having a feel for what the profile of any...
Transmitters on stage and deco bottles are dumb. It is a team resource that needs to be easily passed around.
I don’t get AI for BM doubles either. You rarely check it anyway and it is easy to do. I put my son on AI when he started diving at 10 because he had trouble clipping and...
Having it on the left makes it possible to dump while on the trigger, not easier. You can easily hit the dump without switching the light. Depends on the need. On the trigger needing to dump a small bit, I would normally not bother to move the light to the right hand. Setting up the gear...
And Gavin speeds can very dramatically. I had one with a blue tail that no one wanted but was faster than most in the fleet by a large enough margin to make turning it down enough to match speed a chore. Even sounded different. My other one had constant trigger issues as mentioned by AJ.
My technical diving predates the existence of the fundamentals course. But, I do have two good examples. My wife took the course purely for a rec pass with maybe 20 dives and had no issues passing the class. My son is too young to formally take fundamentals, but dad dives with several GUE...
Others have answered your question regarding checking with an instructor.
I have both of the lights you are considering. I use the flare for sidemount but actually prefer the focus 2.0 for light output. The focus has much better distance and the more focused beam helps with picking out...
