Apex US4 hose routing

[mrjcrickett]

Hello everyone, I was wondering if one of you out there who was using the US4's on doubles would post up a pic of your hose routing. Thanks!

[mrjcrickett]

That is real weird. I typed "Apex" real fast....typed my question....saw that I did not type "Apeks" and re-typed the title...but it will not change...I look like a real dope!

[WarmWaterDiver]

It says "Apeks" in the title of post one while I'm viewing it.

I can't answer your question though - I don't dive Apeks.

You might drop a PM to rescuediver009 - check out his avatar.

I have not seen anyone dive these (either double or single).

[Tamas]

they are the same reg as the DS4 but unsealed - hence the "U" designation

Thanks Tamas. This is just what I needed.

Hey he doesn t know everything;) I personally agree my avatar is much better:D

Cheers Alex

ps We are good friends thats why I make fun of him.

If you plan to use Al cylinders it won't route as nice or look so pretty!

There is a trend in cave country to switch Hose #5 and Hose #1 these days.

I don't do it, but I'm just puting it out there.

routed as shown above in the previously posted photo.

What is the difference between the DS4 and the US4?

Environmentally sealed VS unsealed......other than that identical .

Makes perfect sense, clean up the x-cross a bit better.....after all the hose configuration is not etched in stone, nor is there a "rule" of what has to be done.....do what works for you as long as you keep the primaries on separate posts.

No... 'cause the aluminum cylinders have shorter necks than the steel tanks. As a result, you can't set the DS4s exactly even like shown in the pic above.

The hoses coming off the "bottom" are forced into too tight a bend. Instead, you have to leave the first stages in a little bit of an angle... tilting in toward the center. Now the hoses come off at angle. This is O.K. but at its worst it can affect hose length. For instance, I have to use a slightly longer backup reg hose because it comes off the "bottom" of the first stage initially pointing to my left, then it must bend back towards my right so that it will go over my right shoulder.

Hmm... I have some pics somewhere... I'll look.

[GreenDiverDown]

Here ya go...

[Tamas]

That's a horrible angle, what if you angle it more to relieve some of the strain....at times like this is when the DST would come in hand

[GreenDiverDown]

The first two pics show the "horrible" angle when the DS4s are forced into a flat or even position.

The second two pics show a reasonable amount of bend when the first stages are tilted in a little bit. Unfortunately the way the second set of pics were taken, they don't show this very well.

But that's typically how DS4s are used with the short neck aluminum cylinders... tilted in to relieve the tight bend in the Primary and SPG hoses.

I should also point out that this appears to only be a problem when using a Halcyon/Sea Elite-type of manifold. I'd have to double check, but I seem to remember that my friends that use the OMS manifold don't have this problem. If I remember right the OMS sets the regs up a little higher.

It really isn't a big deal... most people use 'em just like I've described. I was just pointing it out so guys that put this together won't be surprised at how it shapes up. Most pics floating around the web are of DS4s on steel twins... so it can be a bit of a surprise when you set 'em up with aluminum tanks.

I think that I had to switch out my 22" backup reg hose to a 24" one. That was really the only problem.

While there are no 'rules', having them crossed keeps all your primary gear (primary reg and primary inflation - wing) on the right post and all redundant gear (back-up reg and back-up inflation - drysuit) on the left post.

The "normal/DIR" way alows you to shutdown your post while you dump your wing incase of a freeflowing inflator + iced up hose. Which is the main reason I don't switch.

And how would that interfere if you switch your wing and DS inflator?!

You can't dump with your left hand while you shut down your post with you right hand if you switch them.

That is not what I said at all.
I said:

I have 2nd stages on both yes. Is that what you are calling primaries?

I'm talking about your primary life support on one post...your main 2nd stage which is on a 7ft hose and your wing lp inflator.


Redundant life support on a different post...necklace 2nd stage and dryduit inflator.

Supposedly, in a "Roll-off; Break-off" situation involving the left post, what you describe leaves a working regulator (e.g. wing inflator) to still use during a donation situation. That's part of the thinking of leaving the wing inflation on the left/primary side.

It would suck to be in that sitch, but gas from somewhere is better than nothing (or to keep you from fighting your buddy over the reg you donated him). :D
