Backup Regulator Necklace Hose Routing

[RobPNW]

Just finished ordering my hoses and accessories from DGX:

- Primary 2nd stage- 84" flex hose
- Backup 2nd stage- 22" flex hose
- Inflator hose- 22" flex hose
- Swivel eye SS snap 3" for primary 2nd stage
- Swivel big eye snap 4.5" for gauge
- Threaded dust cap for my DIN 1st stage

Already have a 110 degree elbow for the primary 2nd stage.

The BP/W kit comes with some 2" EPDM loops for the inflator or otherwise and it comes with a length of cave line. For a dollar apiece, I got some of these to try out or at the very least, as part of a save a dive kit:

Hose Clip Retainer

Use this handy reusable bungee loop retainer to attach a clip or bolt snap to any SCUBA hose. Sold individually, order one retainer for each clip you need to attach.

if your computer dies and you immediately end the dive and ascend, why carry an SPG at all?

Mainly because you don't know ahead of time that the computer will die, obviating the need for the SPG.

To be fair, there are some with AI computers that don't have an SPG separate..... Exactly because of the "dead computer=aborted dive" scenario.

You mean the secondary regulator?

An elbow on the primary hinders donation. An elbow on the secondary can aid placement, but can also affect the reg position in your mouth if the hose length isn’t correct.

It doesn't seem like it would ever interfere with anything but I know dangling gear is frowned upon so I thought I'd ask. Is there a most common length for the clip? The ones I see in pictures here appear about 4".

Also, on the HP hose, I have a very simple console with SPG, depth and compass as a backup if something goes awry with my watch AI computer. Hopefully, I never need to use it. Is it reasonable to clip that console off with a simple retractor instead of a fixed clip? If my computer stops working or I feel the need to use an analog compass, I can pull it forward on the retractor. Otherwise, it just stays where it is.

So let me address this separately.

1. Retractor. I hate it as well. I actually have one personal encounter with retractor. Being in CA, pacific water, we have a lot of kalp, carry a lot of weight, retractor is nightmare for getting caught in thing like kalp. And most retractor is stainless steel wire, typical small knife just won't cut it. If you use one, make sure you have a cutting device that can cut that.

2. Console with compact and backup computer and spg. For me, backup computer is not absolutely needed, so chance of that getting used, of the need to be in console is zero. SPG is a rare look at device. a few time in a dive. Compass, it is the most often look at device. To be able to look at it comfortably, console hose needs to be long enough, but then it is clipped off, it is a super long bow. I still have a picture of myself with console when I started. Hose everywhere. Let me see if I can upload it.

So compass on left wrist, keep backup computer in pocket if even needed. 24" hose on metal SPG is the cleanest setup. It is what @Nemrod has been talking about.

As a purely recreational diver, if my computer dies the dive is over... When I learned, they still taught no faster than the small bubbles as a reference for less than 60 ft a minute ascent rate, and you can eyeball 10 feet-ish for a safety stop if needed. If you are getting into any mandatory stops, then you're getting into tech and really should just have a backup computer.

I think it is even simpler than this. We are not solo diver, right? If your computer dies, signal buddy, end the dive. Ascent rate and safety stop is led by buddy. It is the buddy/teammate's responsibility to led the exit if you are compromised.

If what you're saying is true, and if your computer dies and you immediately end the dive and ascend, why carry an SPG at all? Not a smarty pants question. I see your logic, but if the rule is no computer = dive over, doesn't it follow to not even have an SPG? What am I missing?

Well, SPG tells you when you end the dive based on air supply, right? And computer tell you when to end the dive based on N2/O2 loading. One of them hit the limit, you are going up. The only reason you haven't gone up when your computer dies is because neither of them hit the limit. At that moment if you ascient, you will have enough air, because if you don't, you should have ascent earlier.

 

[Wibble]

Given that you have a single tank, no backup and that you can’t breathe water, the SPG is probably quite important.

If I were you, and already had the console, I'd just tuck it behind a strap or bolt snap it as James recommends. You'll find that you can read the guages while it's still clipped to a d ring (waist or chest) and if you need the compass, you can untuck/unclip it and have it in hand while navigating.

Just my opinion,

James

I tied one knot at 10 feet, two knots at 20 feet, and three knots at 30 feet on my SMB line.

True, and good point. I am fairly often solo.... so I don't think of the buddy as a resource as immediately as I should!

I believe that his comment was in regards to an air integrated computer, and hence no separate SPG being an option.
