Atmos Mission One

[scubadada]

I looked at it earlier and the presets are labeled:
Low 45/95
Med 40/85
High 35/75
Custom

Thanks, can you run the 1st, clean dive air NDLs off the planner from 60-130 feet for the three presets?

And now for the Pictures....... If you want some pictures compared to an OCi, Geo 2, Zoop or Genesis, let me know. EON and Peteral available, but those are different.

Both units are set to Max Brightness.

I got hold of the M1 last week, and dove it over the weekend.. and gotta say there are a lot of things I really like about it.

First thing, after reading this thread I was worried about the screen brightness. Getting it out of the box at home I also thought it appeared dark. However as the screen is reflective type, the more light the more clear and vivid the screen becomes, take it outside and damn.

I quickly found out that on dives during the day I didn't need the backlight on at all, so disabled the active wrist function, and during night dives the backlight is sufficiently bright. I'll add more info, thoughts, comments later..

For ref, in planner it appears ft is converted from meters and rounded so for example 16m = 52ft / 17m = 56ft. I recall there was a comment about stepping in planner earlier.

Planning times are the same for both m/ft

Hi @hsinhai

Thanks for running the NDLs

If the computer is set for imperial units, is the planner still in metric with the imperial equivalent? In other words, are you able to do planning for even number of feet, i.e. 60, 70, 80, 90...?

Could you post a picture of the screen where you choose the presets and the corresponding GFs are shown?

 

[scubadada]

Interesting. Shearwater and Oceanic run on their metric planners. Of course, gives no insight into how the computers would run repetitive dives.

This is the low/med/high settings are selected, you can see they show the GF they use for a particular setting. Custom you can adjust GF values.

If you set imperial the planner is in imperial, the displayed depth is rounded from the metric

On repetitive dives, it worked much better than my leonardo cressi, which is the main reason I was looking for something more adjustable/aggressive as I am frequently hitting deco on the leonardo computer on repetitive dives, while my friends still have NDL. One friend has a Zoop and another galileo.

{edit} here is a shot from the 2nd dive of first day diving (D1:20M 1hr 17m / SI:1hr 28m / D2:19.8M 1hr 14m)

my leonardo hit deco while buddies were all over 10m remaining, by the time I reached SS I had built up a 9 min obligation, had more than enough air to serve the obligation, so I always serve it so as not to lock the computer for 48hrs because I use it for downloading data to my logs.. leonardo is already running on most aggressive, but it seems to carry a lot of residual nitrogen on repeat deep dives cutting dives short?

Thanks @hsinhai, I appreciate your posts

The Mission One's settings are clearly labeled with the same GFs as the Shearwater rec presets. The Atmos deco algorithm appears to be rather consistently a little more conservative than Shearwater for clean, 1st dive. Interestingly, I also have a Dive Rite Nitek Q. It's clean, 1st dive NDLs are more in line with Atmos than Shearwater.

That now makes it clear regarding the planner. Though the units are imperial, the depths are translated from metric. The answer to my question is that you cannot plan even depths, 60, 70, 80... ft.

I was told that they don't add any additional safety factor... but after puting a few more dives on this watch, im a bit weary of this computer anyhow since a few other things seem to be off with mine.
