with or without the magnet
during or not during the laoding ... nothing is happening, the screen remains black

I have stopped diving for about 14 months now. My OSTC 2 (hwOS tech) battery was completely empty, the computer didn't react anymore to any push on the 2 red buttons.
I connect the charger on my laptop, the charger starts flashing green.
I put my computer on the charger and the computer reacted by ...

done already but looks that everybody seems to think that it's not true (see my post on depth difference in the forum)

Hello Ralph,

The serial number is 15592

hope this help (because beside the compass not showing the right direction, the computer is also not giving the right depth !!!)

Hello

I had a OSTC 2N that i have replaced by a new OSTC 2 hwOS tech.
I dive with 2 computers (backup/security). My second is a simple old Uwatec Aladin Pro Ultra.

I did my first dives with the OSTC 2 a couple of 10 days ago and did 9 dives (all between 30 and 60 m). The dept differences goes from ...

Hello Ralph


I did a calibration again. the result is even worse.

Now I have a difference between 40 and 50 degrees.

the calibration settings I noted are :

x = - 206
Y = - 993
Z = 1103

what does that mean ?

Thanks

Hello Ralph,

Thanks for the advise.

I exactly did what you said. I put the old SUUNTO compass on a place where there is no iron around at least 1m.

I draw on a paper the North and set the direction based on the N indicated by the SUUNTO. I then remove the SUUNTO and put the OSTC on the paper ...

Hello Arno

thanks for your feedback.

For what I noted, the 1m/1' ascent rate is valid from 3m. There is no such ascent time increase when 6m stops are present.

I'm also in favor to slow down a bit the ascent speed when reaching the surface but 1m/1' is a bit slow at my idea. (I do prefer to ...

Hello karip

I received my new OSTC2 this week and performed many calibrations (also running on v3.01).

I have to admit that the compass is not showing the same direction as a "standard" compass. I have between 20 and 40 degrees difference ... which is huge when you dive in bad visibility ...

Hello,

I'm a OSTC user since several years now (OSTC 2N) and just bought the new OSTC2 with hwOS Tech.
Just playing with the computer to understand how the deco planning is calculated.
I have set the computer to basic setting for Deco:
- Deco model : ZH-L16 (no GF)
- Sat/Desat : 85/115
- Gas : Air ...

Hello Matthias,

thanks a lot for your answer.
Does that mean that for OSTC (2, cR and 3), we have 2 options of warning :
- variable limits but not configurable (speed limits being dependant of depth). It is one set of limits
- constant limits (all above 10m/min gives a warning/attention)

but the ...

looking to buy a new computer for my wife (I have a OSTC 2C), I was wondering if the new OSTC2 has the speed ascent indicator : m/sec, graph or both ? and is it possible to configure the value at which the indicator turns in Red (alarm) like it was possible with the 2N and 2C ?

thanks for answer ...

In the "deco calculator" option, you can select showing the NDL as it would be calculated by the diving log software, or by the OSTC computer. When you select the OSTC profile, the "0 NDL" problem is shown... but if you switch to diving log calculations, the "0 NDL" problem ...

@Matthias,

So it means that we are at the very limit between deco and no deco (with respect of th CF 11 & 12 that add additional conservatism in the non GF model).

Is it save to go surface in this state (I mean being at the very limit) ?

This being said, I had difficulty to believe that someone ...

Thanks. I have attached the dive dump.
Hope to hear/read you soon

Hello Matthias,

I will do my best because I do not know how to do it with "OSTC Tools".
I will download the software and will check how to dump a dive. Any manual (in UK) I might download that could help me ?

Thanks

Thanks Matthias ! (tu)

@jb2cool, Thanks

Can Matthias (@heinrichsweikamp) maybe confirm our understanding ?

Thanks

@jb2cool

Thanks but then let's take my example by using a 50% Nx but keeping same deco plan (6m/2'; 3m/4'). the deco plan has been done by using my both gas (Air + Nx50)

Does that mean that when I will reach about 19.5m, my initial decoplan that was 6' (2+4) will be adapted around 19,5m (MOD Nx50 ...

just a quesion about Deco time calculation :

Matthias said that if we stay 1,5 m shallower than change depth, the deco plan will be automatically recalculated to use the current used gas as deco gas.
To be clear, let put an example.
I use 2 gas : Air and O2 100%, all active, all with their correct ...

Apple USB Charger (at least for iPhone 5) is 5V / 1A. So good for OSTC ?
Can some one from HW confirm ?

Thanks

Hi,

I'm a pretty new user of OSTC 2C.
I did a deco dive (max depth 32m) this week and get a deco stop indicator at 3m for about 2min (TTS was about 6min, TTS@+1 = 7 min).
When ascending, we made a stop of about 12min at 15m to explore a small wreck. The deco stop disappeared, NDL returned to 0 ...

Does it work with the Apple USB charger ? they have a higher power like 1A

Thanks

Titus
