Here is a comparison of dimensions, rounded to whole mm.  I'm interested in the Skylife products so the Vega which seems like a bargain is included:

I’m a proponent of visually seeing needles/bars as opposed to just numbers when you need to know info quickly

Many are convinced an analog alti will result in less time wasted staring at it compared to a digital alti. I can understand that it seems logical to make that conclusion. I think it is usually incorrect.

If you're looking at your alti only long enough to realize it is a long way from breakoff time, you should have been able to tell that from the ground. If you're wanting to know if it is 6 or 5k, it takes longer than people usually want to admit to themselves.

I have noticed some videos recently where people spend an awful lot of time staring at their analog alti each time they "glance" at it. Real people in freefall might not match up with what seems intuitive.

What advantages does a Viso/Ares have over the Neptune/N3/Atlas?  Let's disregard price for now.

Only after 30 years jumping did I consider a digital visual altimeter. A Viso II seemed not so easy to see, but an old Neptune II was much nicer.  I've stuck with them since, and think there are many reasons why the Alti-2 product line is superior to the Ares/Viso.  The L&B audibles are more competitive I think, but not the visual altis.  I'm not just a "fanboy" of Alti-2. I think they could have done much better with their new products.  I am also surprised the only competition to the VOG requires an earbud.  Everyone raves about the VOG when they try it, and I doubt my experience will be different, but how long does it take to get one?

At 100% oxygen at 41K feet you are getting the same oxygen you get at about 4000 feet on room air.  So if you ordinarily live in Denver it will be normal for you.  For most people they will be getting a little less oxygen than they get at sea level.  Whether the person is OK will depend on their physiology.  Most people will be.

This would imply we can go much higher than 41k.  

I thought the UK allowed jumping through clouds.  Is this correct?  Does it require being located where VFR isn't allowed or something like that?

Is there guidance for pilots?  USPA says we ought to use a partial pressure suit above 40k, I remember you saying something about a military jumper limit is/was 43k.  What about pilots?

There is no reason to think that the low ambient pressure and temperature can not be dealt with as long as appropriate measures and equipment are used.

This is not true, even with the best oxygen delivery system.  Even you said it was at the edge of what is possible, because it isn't possible for us to expect to be coherent at those altitudes, even pilots.

Wrong thread and wrong forum.

I understand that, but it has been shown that nobody should count on being coherent at 41k, no matter what type of oxygen system is available.  I'm asking what pilot guidance there is for unpressurized flight.

Thanks for the correction.

So in general, nobody but the military and record attempts goes much above 51k.

The altitude when pressurized isn't important to this discussion.  

I have repeatedly brought this up because the description of the incident jump sounded like the pilot was impaired, which is not a surprise at that altitude.

Even with the best oxygen system, are pilots allowed to fly at those altitudes for only a short time?  Doesn't this seem like an obvious question? 

Is there a limitation?  Seems as though pilots know it can't be defended.

Thread bump.

The Skylife Vega/Sirius/Orion have been sold by Rock Sky Market at CSC for quite some time now, which is quite an advantage to have a brick and mortar store to help if there is trouble. They seem to well designed/built and have all the important features at a great price, but aren't popular.  Why?  They didn't catch on even before the Ukraine war.

Alti-2 seems to be on a downward slide. As their military market share continues to evaporate, they're trying to revive their sport line. Unfortunately, it's to little to late. The Atlas Juno is their entrant in the race to the bottom. It might satiate the all to pervasive "hook a brother up" crowd, or it might not. 3D printing allows them to engage in an on demand production model but as most have noted the product looks cheap. The dual mode (audible/visual), menu and revised charging port keeps the Atlas II appealing but it's not enough at $429 when an arguably better Ares II is $399. It will be interesting to see the feedback over the next year related to all of their new products.

 

399 is less than 429, but what else is better about an Ares?  The use of the 7-segment display is especially pathetic on an updated, more expensive than the Viso redesign.  The curved, narrower aspect ratio font of even the oldest Neptune/N3/Atlas is much better.  Doesn't the Ares still show the useless blur of the tens digit in freefall?  How could they not have that on their list of things to improve?  Did the user interface of the Ares improve over the Viso?  

Has anyone seen a Jade/Crimson audible?  Their printed cases are likely an indication of how rugged the Juno will be. How can they not be targeting the VOG as a competitor?  

New L&B and Alti-2 products aren't impressive compared to their previous generations.  Perhaps the most meaningful improvement has been durability, but that should have been there from the beginning - not offered in the next gen at increased cost.

I think that may have the opposite effect - not knowing if your equipment is working or not causes stress levels to raise.

 

I haven't had any second thoughts in the 3 years or so I've been doing it, but that is a real possibility, and why I asked.  I've never failed to push the button properly, and don't understand why so many don't trust it to turn on.  I don't like being asked by others to confirm their light is blinking.  I suppose the motivation for my idea is largely to stop people from bothering me when I am concentrating, and wishing they wouldn't be distracted by their lack of confidence in the camera to turn on.  

The camera can be confirmed to be on by looking at the display, so it can be confirmed in the rare scenario where I might not push the button cleanly,

I am leaning more towards a Pilot or a Safire 3

If you're considering used, then again I'll say you should consider lots of other possibilities.  The Safire 3 is newer and more glamorous than the Pilot, but why those 2 options?

Realize the trusted instructors, riggers, and other sources of expert advice can all be trusted to give you advice and it will not agree.  Assume everyone is biased and are prone to biased assertions of good and bad this or that Ford vs Chevy stuff.  Keyboard warriors such as us can help sort it out with time, at least you can get a multitude of opinions, you will learn, and it helps kill time.  

I've been using a Pilot 210 for the last 12 of my 42 years jumping, now at 1.1 WL.  At such docile loading, there are a lot of good options that you'd like.  Read all the marketing you can, that way you'll learn some and be reassured, because they'll all tell you their stuff is the best, so you can't go wrong eh?  

My idea is to promote the practice of setting gopro cameras so the red light doesn't flash when recording.  Better to just press it firmly and quickly - not bothering anyone with a camera check, not using a small mirror.

Cameras are enough distraction, this would help in my opinion.  Plus, people look silly trying to mime their flashing light check request before the camera even had enough time to start flashing!

I've been doing this for the few years I've been jumping a camera.  What do you think?

Yes, my mistake, aluminum still for the Atlas II.  As for the Juno, click the display image and blow it up.  You can see the 45* zigzag from the printer and it looks like they are printing with 2 perimeter walls.  If Alti-2 was proud of it being 3D printed, you'd think they would mention that.

Quite right. It will be interesting to see and feel them for real.  We are still left wondering which is the better choice if durability of case and screen is the goal.

Maybe they had a second release of the N3, but my N3 and N3A both use microUSB, not USB C

Correct, I wasn't thinking right, corrected in a follow up post.

the Atlas 2, which appears injection molded

Their website says it is not injection molded plastic, "The machined metal case is crafted from aircraft aluminum."
Some aspects of the Juno case appear to be printed, but those very consistent grooves around the perimeter - I would not have thought a printer could do that, but they are ordinary for a injection mold.

at least the N3 had a metal case

We should be open to the possible benefit of a non-metal case if it can be clearly shown they are tougher.  Plenty of plastics and composites can be quite tough - good at absorbing energy without damage.  Of course a metal case might look sturdy but actually be too thin to resist dents, and the plastic/composite might be more likely to fracture than dent.  Maybe the manufacturers are reluctant to highlight in terms of data regarding how fragile older designs have been, as all the manufacturers have made general claims about new designs being tougher without meaningful data.

We are left wondering whether the Altas 2 or Atlas Juno are tougher.

I'm pretty disappointed to see the Juno selling for $359 USD and it's in a 3D printed case.  Altis have always been expensive, small market, all that - but at least the N3 had a metal case.  Knowing I could print the Juno case and the hardware would be a pittance compared the price, it almost offends me.

How sure are you it is printed?  The texture looks like an etched pattern from a mold rather than printing, and the very slight but very consistent groove that goes around the perimeter of the outer face makes me think it is a mold.  That's just my quick observation as someone with a lot of plastic injection parts experience but not so much printing.

The N3, which predated the Atlas, had applied the USB-C as an improvement over the original Neptune.  No change there.

The buttons on the N3 and Atlas already had a good tactile click feel to them, even with gloves. No improvement needed, so very little value to improving something already good.  

 

Sorry for being so wrong about the type of power connection, I wasn't thinking right, the N3 doesn't use USB-C.

Seems to me like new more "clicky" buttons, and USB-C instead of microUSB for charging.

I understand the Juno version, a little cheaper.

For the Atlas II, they don't make it clear what has changed.  Perhaps buttons with even greater tactile feel, and perhaps a better battery?  

They might have had to redesign it due to components becoming unavailable.

We commonly have the 200+ pound newly A licensed jumper searching the classifieds for a rig with 190 main and room for downsizing.  The newly A licensed jumper didn't decide on his own it was the right size.  Changing the culture would help.

I didn't realize this was such an old thread.
