Hi - I am Graham - I engage in divering (all activities associated with diving but not limited to diving) and I teach technical diving all over the world - many non-native english speakers struggle with pronouncing "graham" so I often just get called GB.

I dive both bov and dsv without any preference … just what my hand comes to first during setup (or what students/teammates have). If you set your harness properly you will not get tipped over - control your equipment don’t let it control you :)
Hi Graham, what hose types and fitting did you use for the suit inflate to get the two inflate hoses pointing different directions? What type of hose from the 1st stage to the T ? Thanks in advance.
Thank you for sharing. Our group weren't the most disciplined wreck divers and we weren't allowed to penetrate the Saratoga. One guy was particularly bad at silting up the place...and he could never understand why.
@@gbdivering I absolutely loved diving on the Nagato...all the history. The accommodations were comfortable. I enjoyed the afternoon swim in front of our rooms. You knew it was dinner time when the shark fins would appear in the bay. Another memorable event was getting to the bottom. We did that as fast as possible as we were diving Air and deco was 75% O2 hung from the dive boat on a trellis of sorts. Anyway, during one dash to the bottom we saw two sharks swimming up to meet us. They passed me and one shark head butted my friend in the gut. He didn't bite, just a head butt. It sorta frightened us, but by the time we reached the bottom we were so under the affects of narcosis that we brushed it off.
@@gbdivering I did not see the longer videos. I'll look for them. We traveled to Bikini in 2007 and agree, there are better dive destinations. Truuk Lagoon was better and the Cayman Islands wall dives are more beautiful.
@@dougallen5873 here’s one USS Saratoga uncut penetration - dentist chairs, CIC & Admirals Quarters - loads of details #diving ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2VRDcSB0XYQ.html there’s also some 360 vids so you can look around and compare to your trip
I just wanna say a big thank You for doing all these videos, they are nothing but awesome! Keep them coming 🙏🏽. I know 2 Swedish’s guys who took your CCR 2 class and they were thrilled 😄
Very interesting video. I was always told that using your lungs for buoyancy is the proper way to do it and a skill you want to master as you improve your diving skills. Rarely ever touching your inflator is being seen as a good indicator for having mastered your buoyancy skills. I guess this is kinda true/viable as long as you only consider recreational diving, but it certainly gets you in trouble on a rebreather where you can't use this technique anymore. Thanks for sharing this very different perspective on the topic.
When you get to heavy tech or rb your lungs are ineffective - in rec diving you will still benefit from proper, precise buoyancy control in breathing and relaxation which will translate into better situational awareness and most importantly fun :)
Do you run CCR2 for 6 or 7 days if you have non tech2 divers on the class? As tech1 divers are missing bottle rotation skill, t2 deco theory and hypoxic protocol
Thanks for your comment and I agree partially… Somehow if you don’t know how to control your airway then you can close your nose (or wear a mask). I would suggest developing airway control and awareness of what the rebreather is doing and why it’s not working (eg nose breathing)
Hi Graham, is there a particular reason why you don't do the bottle rotation at 6m? So you can clip off both the bottom stage and the 50% to the leash and only have the 100% on your chest?
You maybe borrowing somebody elses cannister or just don't have the bolts easily available where you are at that time. I also i only being able to find coach bolts with much smaller heads in a4 ... and life is too short to be trawling around hardware stores looking ro bolts. But most importantly you're not balancing your rig on a stack of grommets ...
Interesting perspective. This all makes sense to me, but it's certainly not the trendy thing to say. The conclusion I eventually came to was - to use breath control for temporary adjustments (eg. Going over or under things) but as soon as you are on a new "level" adjust your BC so that you can return to natural breathing. I've certainly had more than my share of splitting headaches from skip breathing and shallow breathing.
Thank you for the video! Must have watched it a hundred times by now :D May I ask what regulators you are using for oxygen, dry suit, and diluent? And why do you prefer a scubapro regulator for the oxygen? Would you be worried about using a piston regulator in freezing conditions? Thank you for your time!
Wow, this music is so much more fitting! Also... don't show me that m8, I would be dead in the first 20 secs of that video if I can't grab a shot line... xD
Great content as always! It's incredibly useful, especially after taking my class. It helps me refresh my memory on all the skills we covered. Thanks, Graham!
