V4Tec / BOV a big up to Stagonset

Mark Chase · 23rd November 2006, 18:38

OK so I slip effortlessly in a silth like dive god fashion into my rebreather harness and casually flip the loop over my head, and then there is a thwack as the V4Tec BOV whacks me in the arm???

The inhale hose fell off?? Now thats not good. The humble cable ties holding it on are just not up to much. I then struggled to re fit the hose and attach it with a new cable tie but a hefty pull just pulls it off again.

Thats scary. What would happen if the hose fell off under water? Obviously first thing is a lung full of sea but when I switch the BOV over to OC I wonder if i can keep it all working OK with one hose completely off?

I dint like the odds so I noticed a link on here to Pratt Lay Limited. trading on the net as Pratt Lay Ltd - Moto Guzzi Products An unfortunate name perhaps but they have an excellent range of thin Jube clips so I grabbed two for the BOV and four more thick ones for the tanks an a 50mm long 4mm bolt for my HUD bracket.

Any how I placed the order @ 635PM Tuesday and they turned up this morning less than 48hours later. Having had a quick look see they look really nice.

So well done Stagonset.

You could also fit the standard YBOD hose fittings on the V4TEC easily by trim away the 90-bend off the split rings that hold the hose to the V4TEC hose connector.

Sorry, I will try to describe it a bit more...

The standard YBOD hose connector has 4 main parts:

The larger round part that screws into the standard YBOD DSV. This is now replaced by the V4TEC round part.
2 separate threaded rings that go over the hose once the hose is pushed onto part 1 above. Their function is to hold the hose tight and prevent the hose from being pulled out from part 1. They have 2 ends: the flat end and the 90-deg bend end. The bend end hooks to part 1. Trim this 90-deg bend away so it will fit since the OD of the V4TEC round part is larger part 1 from APD.
The smaller round part that go over part 2 to hold them in place. Use this the same way.

So effectively, you substitute part1 with V4TEC-supplied connectors. And trim the 2 threaded rings so they fit. The rest works the same...

Hope that is clear enough, I am busy packing or else I could take pictures of mine for you...

You sure do have some dramas with your kit!

Good for you that you're prepared to share the mishaps with all of us.

I'm thinking of a Golem BOV but Martin P says they might have theirs out for the London Dive Show next March.

Having an AP BOV would make servicing easier. Least it could be left on!

You know how AP feel about third party goodies.

It is not that hard to swap the Golem BOV out befeore sending it in for service. Just unscrew it and put the stock back in. Might take all of 30 seconds

Only if you do it really slow. The Golem BOV is a nice piece of kit.

I'm not sure I would hold my breath, the APD BOV has been a long time coming, I have a feeling it will probably be launched around the same time as the Oceanic Rebreather.

Personally, I'd rather go for a BOV with a proven track record with that particular product.

Cheers

I am awaiting delivery of a V4tec, and was abit concerend after reading Mark's post.

I have since looked into the matter and at the connection schematics (the BOV is not in my hands yet) and it seems a pretty tight fit and proper design with TWO nylon straps having to fail for the hose becoming disconnected.

Standard second stage mouthpieces are held the same way and they do not come off that easy (I never had one come off).

Mark, how many nylon straps did you have on each side and how did they break (or how did the hose actually manage to come off)?

I have a feeling it may have come off during transport before you started the dive with the hose been pulled really really hard for it to be displaced as you describe.

The hose was held on by a cable tie set into the recess grouve on the mouthpiece. There is only one grouve so only one cable tie on each hose.

It fell off when I had the mouthpiece back over my head whilst kitting up. I fliped it forward and it was in two halves.

The cable tie had not come undone but it may have streatched.

Bearing in mind I have yet to put my hands on the V4tec BOV (hope the doorbell to ring anytime soon) and try the unit, if you look at the enclosed picture it looks like there should be two cable ties to hold it in place.

Having said that, from the schematics (prior post) it looks to me that the second cable tie closer to the V4tec unit is of little use (or may be not?).

Please, let us keep on sharing our experiences with the unit which I believe is very useful and I Hope to see in due course and APD original integrated BOV.

I have chosen and quite quickly (at the end of my Level I course) to swap the original DSV to a BOV because the original DSV seems to me has a lot of potential water ingress entry points, and I had experienced before on OC not a CO2 hit, but fatigue and hyperventilation. No way I could have taken easily off and switch regulators while hyperventilating (plus i was training in very cold water with a wetsuit and I was wary of how i could have thrown up if i had to through the DSV...).

You will find that its very easy for the cut end of the hose to drop into the groove. It takes a bit of patient fiddling to get it out and on to the next flat. Then you line up the bottom of a crinkle in the hose with the groove and use a cable tie.

I could be wrong but the photo looks like a badly assembled rig with the cable tie on the flat beside the groove and the end of the hose in the groove.
I think what you think is a second cable tie is in fact the exposed Dural of the side piece.

The sketch earlier did a much better job of explaining it.

The cable tie use in the photo is definatly too wide. It needs to be slimmer to push the hose down inot the groove.
