component shop somewhere ??

have been googling  to much  found loads of old stuff on rebreathers one
even made from a 4 inch soil pipe tee peice. also a lot of pages on
Gavin Scooters  any one know where the motors come from ?. no i dont think i
will be building one just intrested.

Halcyon buys from different sources.  I doubt that much of anything is
actually made by them.

If my memory serves me, the Gavin Scooter is powered by a trolling motor.
They have a rather impressive amount of thrust and a relatively long run
time.

Mako scooters, rewound to a more exacting specification.

David,

Until very recently, the inflator on Halcyon wings was outsourced and
was also used on some other BC's. However Halcyon now manufactures
their own inflator in house which includes SS inflate/deflate buttons.

thanks Bob  but that rasise two questions  :-

1            How do I tell if Ive got an old one or a new one.
2            what other BC had the same inflator ??

Regards David.

Probably just by checking the inflator - if the inflate/deflate buttons are
red then it's an old wing. If they're silver, however, it's a new-style
wing...

And if they are black?

The silver needs cleaning ?

Earlier (?first) series wing.

Slightly OT, does anyone else find them a bit awkward to use? I find the
deflate button a real pain, not exactly ergonomically designed. I've started
just pitching forward slightly and using the valve at the base of the wing
because it's easier!

I think that's probably the general idea as the inflator hose is often
looped through a small peice of bungee attatched to the left hand chest
D-ring so it would be rather difficult to dump air through the inflator
unless you're vertical in the water. As you're supposed to ascend in a
horizontal position, it's much easier to dump excess gas through the pull
dump at the base of the wing.

I tried that with the bungee, but the deflate button became virtually
useless as I could no longer raise the hose above its exit point from the
wings bladder, and thus dump air (unless the bladder is full - i.e. not
often).

As 99% of the people I dive with use regular BCD's, and it's a BSAC club, a
vertical ascent / descent position suits me best (unless its gradual, i.e.
up a slope or similar) - so a hose deflator that was easily operated would
be welcome. Apart from all this, I'm still getting used to my first wing, so
it's all a bit new anyhow.

Yes, that's the point - the deflate button does become useless as you're not
supposed to use it when doing a horizontal ascent - just lift your arse
slightly, pull the dump on the wing and bob's yer uncle! ;-)

Just because they ascent vertically doesn't mean you have to, surely?
Personally I find horizontal ascents more natural and are almost certainly
safer too as there's no pressure difference between the top and the bottom
of your body...
Tom Walek, MD - 29 Nov 2003 22:12 GMT
I do not like the new inflator because if grasped with the right hand using
heavy gloves it is possible to inadvertenly depress both the inflate/deflate
button. I believe that is the genisis of this design, to allow you to breath
the wing dump as a backup regulator. I do not think it is a good design and
I think it is potentially dangerous.

Actually, it's nothing like as difficult as you would think, providing that
you use reasonably stretch bungee!

Indeed.

My only complaint about the older inflators is the mouthpiece which points
45% outward is a PITA.

Actually I thought it was the new inflator that points out at a 45% angle...

Good point - ok, black *or* red then means it's an older-style inflator...

Plastic inflate/deflate buttons.

Black or red.
