Now that you say that Bryan you are right. I am good to go then because all of my regs have long yokes(Mistral, Jet-Air, ROYAL DA). Would not mind having an extra banjo though and its getting added to the wish list.

Of coarse my Phoenix is what it is.

Notice I said ROYAL DA. as my DA Aquamaster has a Royal nozzle in it :lol:

Just salvage a long yoke off of an old Conshelf. Late Mistrals came with a long yoke, I have one.

I know that Captain and I are "vintage" enough as well as others who actually dove this junk when we actually used a J-valve instead of a SPG. We also planned a dive to a certain depth and weighted for it, thus no BC. I haven't used a banjo or Phoenix on a J-valved tank in a long time. Why for?

Simon,

I'm still perfecting my BC-less diving. How did you plan your weight for a certain depth? For example, I use no lead with my steel 72 in the springs and I get down to the max depth fine, and can control my buoyancy with just my lungs. I can even hover without my BC now, which was tricky at first because I was taught how to dive with a BC only. Is there a way to know a change in weight for your target depth, or is that just something you picked up from experience?

Basically trial and error. Keep records, etc. And when all else fails, keep swimmng. Only when you are stationary do you sink or float. I sometimes think that this bouyancy issue is over-blown.

That's too funny man, that's what I did when I was too heavy the other day. I felt like a shark because I was swimming in circles watching the students when I was slightly too heavy.

It is nice when u are getting ur weight down to utilize drop weights or weight pockets. That way u can shed small increments of weight while diving. It is also VERY important to log the weight u used with equip and neoprene, like Allan already said. Many newer divers dive WAY overweighted. I know I did when I was new.

I will have to say that you're good about logging your dives. I can't remember when the last time was that Nemrod & I logged a dive in a dive log. :lol:

To give you an idea about weight variation. Rob and I were diving this summer in the St. Lawrence. We were diving a wreck called the Daryaw, deepest was 95'. Tanks were steel 80s wet suit for me was a 6mm, Rob had a 3mm with a 3mm vest, I think. Rob had no weight and I had 3#. We pulled ourselves to the wreck which starts at about 60'. At that depth we were close to neutral but at the mud at 95' we were heavy. So you can see how heavy a modern diver would be when he enters the water with 16-20# and then must really inflate at depth. Like Rob says, using drop weights helps in the shallow part of the dive which you leave and retrieve on the ascent. I am sort of into rocks. You don't have to worry about someone thinking "looky here somebody lost a weight". If I use a drop weight, I have my name and its purpose written all over it. Now if people would take the time to read it.

That would be as in NEVER :shock: .

I really like the swoosh, swoosh of a Mistral. It is just one of those things that makes you happy and you know all is well with some little part of the world for at least a moment.

This is an interesting thread.
I started diving Mistral in 1963 but I have learned more about it just reading the answers to the original question. I am convinced that the Vintage Double Hose Divers have the most collective knowledge in the diving community.
I would post more but I feel stupid in the company of genius.

You must be smoking something weird. I know most of these guys, and genius is a term that doesn't apply. Old, maybe, experienced, most likely, genius, no way. Keep on posting. We all express moments of stupidity. Most of the time that is the norm here.
