How to route can light cord

[cascas]

It depends on your light head. If it prevents your wrist from bending upwards then you are correct. With a small light head that lets your wrist bend, it's not an issue. Light heads are generally getting smaller, so it might be worth revisiting at some point.

There is no need for revisiting anything, because there is no need to transfer the light to the left hand. The cannister stays where it is because of the use of stages.

Just the fact that you might be able to bend your wrist while donating is not enough justification.

Too many divers are diving in areas they aren't ready for. If you can't pick up a light cord and keep it out of the dirt, you have no business being there to begin with. I imagine that the same jokers who are dragging gear through the mud are the same ones leaving handprints and fin marks.

I agree the proficiency level of many cave divers is far below what it should, be given the location of many of those marks in areas where full cave or equivalent training is required. With something like a light cord, I think it tracks back to a larger issue of being excessively task loaded for your ability or experience level and/or having poor situational awareness or kinesthetics.

So for a recreational or even technical diver not using stages the reason is...?

The reason is that it's always there no matter what kind of diving you do. Also, the SPG is on that side. If you have the canister and SPG on the same side the SPG hose will always be caught by the cord.

I didn't expect so many responses when I first posted the thread. Thanks to all that have been a part of the discussion so far. There are a number of situations that I had not considered. Please don't stop what, in my eyes, is a good discussion on the topic.

I am not going to spell out all details here... Things are done for reasons, all but a few I completely understand. If you want to know them all, go do a course, if you don't have the aspirations to ever become a technical diver, then why bother ?

Why would you change from left to right just because you don't carry stages ?
If you NEVER carry stages, you might use a scooter, if you also never use a scooter, why dive ... just kidding... It is a system, the system works for both rec and tec. But the system only really works as a whole. Anything else just has nothing to do with technical diving as far as I'm concerned...

Try it... as soon as you extend your right hand with the reg in it ( alway by the hose, never by th cover, the OOG diver needs to be able to reach the purge) you will blind the OOG diver.
Your light goes left....

Sorry, but it works just fine. I've done it plenty of times. I dive a Salvo 35W HID and I haven't blinded a buddy yet. Since you're simply offering your reg to your buddy, you can very easily grab the LP hose next to the 2nd stage, drop your head and extend your arm, and point the beam to the divers right (your left) while extending your arm and offering it to your buddy. I've never had a problem with it.

I use my left hand to inflate my wing and check my SPG and I prefer to keep the light head off of it. It may be non-DIR, but I don't give a grap (this isn't the DIR forum). It certainly isn't non-hogarthian and it works just fine for me.

Now to the OPs question .... I keep mine free, not behind the long hose. The reason is that I frequently clip the light head off to my right D-ring. In those instances, it's way too easy to trap the long hose if the light cord is routed behind it and then clipped off.

And then with your light in your right hand get the longhose form under the cannister waving your light from here to there, creating a disco fever... All cool and well, but in cave that will not score points...or work... or be appreciated...

But if that is ok by TDISDI, it's fine by me... Something I will have to take into account next time I am about to enter a cave...

 

[jonnythan]

Yeah, I was going to say that in practice and especially in daylight moving the light around like that is no problem. At night, or in a cave or wreck, and swinging the light around that much adds a lot to the confusion.

That's a typical GUE response - "take the course".

I'm pretty happy with my non GUE trimix, full cave and DPV cave certs - and I'm happily diving sidemount with my light in the left hand. I just can't bring myself to go back to backmount just to take a GUE course and get dogma rather than a well considered explanation.

I was hoping you'd explain why it a right hand light would be problematic for a non DPV, non stage diver, but no luck on that. Failing that, I thought maybe you'd expound on the advantages for a stage diver, but no luck on that either, so we're back to "do it that way because I say so", and I've never found that argument very compelling.

News flash maybe, but if you have an OOA in a cave with a diver having to maneuver to accept the reg in a real world situation (rather than in a choreographed training situation where proper form is a priority) you're already going to have some disco fever happening, and that will clue anyone else in the area who is not already aware of the problem, that you in fact have an emergency in progress.

It's a pretty thin argument against a right hand light.

Sorry but real world effectiveness won't be considered in this case. It's not the GUE forum, but it's close...

The fact that disco is already happening is the worst reason to make it worse... At the point where the OOG diver has a reg and is breathing is, is the moment to restore piece and quiet so the rest of the team can be properly informed of the situation. More disco is not going to help....

To return your arguments... I see no valid reason for keeping the light in the right hand in your posts...
