@Nandodiver What a huge list of improvements. Now also GF99 and SurfGF Thank you Suunto.

To be honest I expected way more from this upgrade…
MIssing features:
CCR mode
Change gradients while diving
Set gas as travel gas

Also…
Someone managed to activate Option to see a tissue bar graph during dive?
Is this refers to the switch window mode that switches to the tissues bar? or to add a fixed bar to the main display?

-After turning on the knob orientation is always reset to buttons left. Would be nice if it stayed the way i configure it.

-Tide info not showing…does it use my current location? Can i somehow select a location and have the tide info shown then?

-In the app itself the underwater route…if i select a location on the map, the underwater route is not shown anymore, and cant find it anymore where that window is at.

I am having the same issue as Ray de Jager regarding button orientation. The Nautic always resets to button-left orientation after shutdown. I was told by Nautic customer support that this issue was known and would be fixed with this upgrade. But it has not. Does anyone have any information on if/when this issue will be fixed.

@Hugues78fr please send an email to support@suunto.com and describe clearly what happens to allow them to reproduce the issue. If they confirm it the issue will be submitted to the dev teams to fix.

Support is quite responsive so they will reachout about the status of the issue.

Hello,

I am having the same issue as lot of here:

the Nautic always resets to button-left orientation after restart
the Nautic, and I, spent to much time outside to get gps position
the Nautic, and I, spent much more time outside to get the compass calibration
regarding tide, even close to the sea or close to La Seine at Rouen, never see after sync or upload, anything about tide

I plan to dive in April to Mexico, would it be fixed or not ?

Thanks.

Found a few again

-gasses added in older firmware: no change and select…black screen
Resolve>remove and make new gasses (bug)

-on the disabled gasses there is no arrow fwd for entering the gas menu, although you can enter to change and enable(minor design glitch)

-forward AND BACKWARDS in extra screens (wish)

-extra lines in tissue graph 10.20.30.40 etc…just lightgrey lines…also in divehistory(wish)

-please show the alarms in dive history on computer(wish)

-fwd knob in a dive while in divehistory does nothing(minor design glitch)

I will sort these with pictures and fwd to suunto support. Keep up the great work!

In reply to ‘Change gradients while diving’

I added an extra view with “GF99/SurfGF” and “Contingency Delta 5 / @ 5” to see what the implications are if you would override the advice from your computer…sort of a ‘second’ calculation running to your main.

It is nice to have this insight…what if i stay longer on a planned dive or even cross the ndl time; what would the implications be…

BY THE WAY …CMAS website has great explanations on the gradient factors and how to set for the ones new to this.
