newbie LP inflator hose routing question

[UWSojourner]

OK sure.......There is no reason to add a piece of inner tube.

I can think of a reason:

Attaching the inflator to the bungee strap puts the inflator too low (at least for my taste).

Simply removing the inflator from the bungee would allow it to fall behind you. You can pick another method (move the D-ring up, use velcro like other BC's to place the attachment more toward the top of your shoulder, etc), but the rubber ring worked out great for us and we don't have the problem being discussed here.

I still think there is a problem with your araingment if your having a problem. I cant offer any solutions with out seeing your gear but Im certine that adding a section of inner tube is not consistant with standard DIR/GUE gear configs.

There should be a piece of inner-tube rubber higher up on the strap (if not, put one there). Put that piece close to the top of your shoulder strap and run the inflator through that. You'll be able to lift the inflator higher and dump more air, more conveniently.

Reminder: If lamont wanted any solution to the problem he would have asked in the BC forum. But he asked in the DIR forum.

This is not a DIR solution. Please restirct responses in the DIR forum to DIR answers.

You ask about the moving the D-Ring. The first question is.. is the D ring in the proper position? The position shoudl be based on your forearm length, not the length of your corrigated hose.

Now more specifically to the problem, is it not dumping because the bungie is too tight that the gas can't flow through, or can you just not get it up high enough? Are you just lifting it, or are you actually stretching the bungie to get it up higher?

2 weeks ago, I used my Pioneer for the first time in a boat entry dive. Entry into the water was by backroll. The inflator hose was not tied down with a bungee cord around the left D-ring. I guess the Pioneer doesn't have this as a standard--I could be wrong. Anway, the DM asked us to enter the water and swim towards the first boat (there were 3 boats) so that we could all go down together. A total of 18 divers were in the dive.

Upon entering the water, I swam towards the first boat to join the rest. When the DM gave us the signal to submerge, I tried to look for the inflator. Couldn't find it. Had to reach over the back of my neck to get to it. By that time, I was the last diver down. I guess that bungee cord is there to prevent the inflator hose from wandering about during boat entries.

Sorry. Didn't know a small piece of rubber inner-tube could sink DIR. (BTW I obtained the Eclipse AND the rubber inner-tube setup from an LDS that is DIR. The piece was on the Eclipse when it was PURCHASED.)

On the other hand, nobody in the previous responses spoke from the DIR-scriptures and said, "Thus sayeth DIR", so I figured it wasn't something that was clear (AND the solution works, was something I encountered and fixed, was straightforward, and was put on my setup by a DIR operation).

Its this type of reaction that gives the DIR-fundamentalists a bad name. :thumbs_do

The small inner-tube is not intended to retain the corrugated hose. On all of the Halcyon backplates, there should be 2 pieces on each shoulder to hold scout lights to the straps. The bungee is the proper way to stow the corrugated hose. If you cannot dump air from the wing, either stretch the corrugated hose outwards (also stretching the bungee) or position the D-ring higher (at the top of the armpit). Did the DIR shop adjust the BC for you and explain how everything works or did they just let you walk out the door with it?

I've got a new eclipse that I'm trying to learn on, and it has some bungee on the left D-ring attatchment that the inflator hose runs through. The problem when I do this is that I have a hard time with trapped air in the BC. I've been looking through various images on the net, but I can't find a good closeup of the left shoulder and my JJ book has been packed in a box somewhere. Is this the right setup? Should the D-ring be moved higher? Could I bungee the LP hose off above the right D-ring? Am I just not doing something right?

Proper fitting of a BP is essential and will help eliminate many of the problems that you discuss. I have two points that I'd like to make with respect to this question:

1) Point 1 is that all too many divers attempt to use the inflator as the primary dump valve. I see this in almost every class we teach. Generally speaking, it's almost always better to get into the habit of using the rear dump valve as a way to dump the air in the wing. If a diver is in the prone position the only way to dump air using the inflator is to break trim and lift your shoulder. This is less efficient for a wide variety of reasons. Most notably if you are dumping air it's because you're positively buoyant. Therefore, if you break trim to use your inflator you'll likley present less drag to the water colum and likely dump more gas then need be, then when you get back into trim you'll need to add air. We call this the yo-yo because you go up and down more then need be. Many divers have difficulty getting into the habit of using a rear dump because they make two mistakes. Mistake #1 is that ther reach for the little string, and with think gloves it's nearly impossible to find until you've developed the muscle memory. We recommend making an OK and then sliding your hand down the side of your tank until you find the valve, once you find the valve then you can get the string. Second common mistake is people just pull the string down, which won't dump air since the hydrostatic pressure of the water drives the air to the top of the wing, so when you pull the string down it does nothing. You need to turn the valve upwards so the highest point is the valve and then you'll dump easy enough.

2) Point 2 involves fitting of the BP. The D-rings should be placed approximately where your arm would naturally reach your chest. Once you establish the baseline for the D-rings the tubing should go slightly above the D-ring and you should have no problem dumping your wing..

Hope that helps..

Hi, yes it was. We (my daughter) dove the unit prior to leaving the dive shop. We then went through adjustments, maintenance (draining water, etc.). The webbing was sized to her by going through the steps I recognized from the DIR instructions on the web. The inflator was looped through the top inner-tube on the left so that the attachment anchored the inflator at the topish of the left shoulder. Looked good to me, seems secure.

Why do you need 2 pieces to secure Scout lights? I thought you attached 1 on each D-ring. If so, I was assuming the lower piece of inner-tube was to secure the light. What is the upper one for?

There should be two (or even threee) pieces of innertube at the bottom of both shoulder straps. The top piece is used to secure the bottom of the light. The other one or two are backups, if the first piece of innertube breaks, you slide up the next and your light is again secure (probably saving that dive).

There should be no innertube above either shoulder D ring.
