Hey guys and gals,

I recently bought myself a new Oceanic Geo Air with integrated air. I like the look of the computer and I like not having another hose to get tangled on when donning my gear on the boat. However, I dive with a university based dive club so the procedures are pretty strict and we must provide NDL time before we get in the water. That being said, it was a good thing I had my old computer on me for my dives yesterday because I couldn't get my NDL to resemble a sensible time.

I go into the dive plan menu - (today it doesn't even have the option for anything below 17.3m)
(I'm in Australia, so all of these are metric)
2.7 - 4:43
3.6 - 2:25
4.6 - 1:25
5.4 - 0:59
6.4 - 0:42
7.3 - 0:32
8.2 - 0:26
9.1 - 0:20
10.0 - 0:17
10.9 - 0:14
11.9 - 0:11
12.8 - 0:09
13.7 - 0:08
14.6 - 0:07
15.5 - 0:07
16.4 - 0:06
17.3 - 0:05

So, what am I missing in my setup that prevents me from planning on the surface?
Setting the computer up from the app seems to apply the same settings to the computer, from what I can see. Planning can only be done on the computer.

Menu

Time:
Pretty generic - time format, date format, alternate location time, dual time and default location.

Gas:
All 3 set up as Air

Alarm:
Audible: ON
Max Depth: 30m
elapsed dive time (min): 60
Dive time remaining (min): 5
Max Nitrogen bar Graph: OFF
Turn Pressure: OFF
End Pressure: 50Bar

Utility:
Units: Metric
Conservative factor: OFF
Deep stop: OFF
Algorithm (NDL Basis): DSAT
Safety Stop: ON
Safety Stop Time(min): 3
Safety Stop depth(m): 5
Dive sample rate: 15secs
Backlight Duration: 5secs
1 Transmitter set up - Air only

I don't want to have to continue to carry two computers all the time - although I understand it is sometimes good to carry a spare as a redundant backup. (yesterday was the perfect example of doing this but I only had it in case I couldn't work something out on the Geo)

Pics of the computer attached and a bonus from yesterday's dive.

Wow. No reply in 5 business days. Suffice to say I would not recommend this computer (or company)

@shannond100 how did you contact them? I emailed the technical support:

"For Technical Support: TAC@huishoutdoors.com"
Hi, sorry, I’ve only just seen this thread again. I took my computer into my LDS and showed them what my computer was doing. The manager has a great relationship with the Australian distributor. He made contact and we went from there. Do you definitely have the latest firmware? I haven’t had any more issues with it since the firmware update.
