At 0:52 he does say "and show your team which bottle you're about to change...". This was done before switching. He does go rather fast though, I didn't catch it the first time watching. He then does show it afterwards as well. Seems like a double checking procedure?
Little tip that I do. I always label a tag my second stage hose right next to the reg with my mix and mod. So this way if I don't have a clear view of my tank label I have it on my reg also. Once again redundancy is best.
Hi Joe, Thanks for your comment. Funny you mention that because that is also what I used to do. Just when you start diving with multiple cylinders and regs, it becomes too much of a hassle to have dedicated regs to each cylinder. When you need to swap out a hose or reg after the analyzation just before the dive you risk running into inconsistencies. But if you take the time to remark and double-check you can add that layer of redundancy. We have just opted to say that the 2-factor confirmation is enough and has proven to be a good compromise between redundancy and practicality.
@@UTD_ScubaDiving I have been doing it for year. I hear what your saying with swapping around lots of rigs. I do my final gas checks right before suiting up for the dive. So at that time all my regs now been dedicated to tanks. I do my check and that's my final label 🔖. When doing many tanks I have had issues with confusion at times with some of the help who may not speak the same language as well. So I have learned as my personal saft tips to always check one last time right before the dive when no equipment will be getting jockeyed around.
Very nicely done! Awesome bouyancy control! Just a couple / questions notes: when tidying up why don´t you swing the decotank in front off you when tugging away the regulator hose? Or maybe there is a point I am missing.
Thanks for your compliments! You could take off the bottom clip and swing the cylinder in front of you, but I think that just adds a step, and with a bit of practice you should be able to do this without unclipping. When we carry 2 deco cylinders on the left, the one you use first is on the outside so the cleanup process is a bit easier.
The change I’ve noticed is now instead of following the first stage to second stage, it is now proven by the pressure/de-pressure of the stage. Seems simple enough.
nice video as always. However I did not see changing the gas on your computer. I know you should switch your computer gas selection after you switch, is that right?
Well I guess, if you use computers to determine your decompression schedule you're correct. You would tell the computer, you have switched to another gas. We in UTD do not rely on computers but on RATIO DECO 2.0 for our decompression planning which is a way of calculating the decompression on the fly and using some simple maths. And ratios between depth, bottom time and decotime. I will soon make a video on this subject.
Peter van den Broek Thanks for your comment! I guess there will always be small nuances in protocols between organisations. At the end of the day the switching protocols and responsibility to switch to the correct bottle during the switch lies with the diver it self. The team observes and confirms. The fact there are small differences should still make team diving possible. Route first then open or open then route should not make a difference I think. We like to confirm that everything works before routing the reg over our neck. If you feel a big difference warrants extra attention. This should be covered in the pre-dive check or dive plan. That way you avoid possible confusion under water. However I have dived with many GUE divers and this was never a big deal.
Confident divers are able to dive with CCR and OC mixed gas divers with no foreseeable problems. If anything, you have extra redundant gas at your disposal.
Tech divers should know exactly how much gas they will need in their deco bottles. I'm not a fan of bending the SPG hose. Buy some proper hose retainers and you won't have problems when placing the reg hose in place while wearing gloves.
Hi thanks for your comment. We have a video on this channel on how to rig or tie a bungee to retain the spg. That way you can unstress the hose when not in use. That is a good compromise between having it nice and in clear view under water, without having it bent all the time also when not in use.
Not sure why you would show external marking to your team AFTER you started breathing on your deco, and not before.
hi BB can you answer this question please
Agreed. I was taught to show the marking to my buddy immediately after the 'look at me'/'switch' signals and get their confirm before switching.

@@UTD_ScubaDiving thanks! this approach is to me unknow so curious to see it, I will ask more question on that video then :-)
This differs from the GUE and the NAUI drill, not very helpful if you dive mixed teams (or are we going for an underwater version of apartheid?)
