I got this as a backup for my Cobalt. I've only used it on 5 dives so far during my AOW quals. Here are some of my observations:
- The instructions are a bit confusing to read straight thru so I found it easier to start pushing buttons and referring back to them when I needed clarification on specifics. But once you get into the flow of how it works, it's not too bad. Since it's watch sized, you can wear it around and practice during your spare time.
- I set it to the Z+ algorithm since the N...DC times were closer to the Cobalt (The actual times were actually slightly more conservative than the Cobalt, but I don't make it a habit to push the limits).
- If you plan to use the compass, it'll take a some getting used to switching between the screens. Best way to calibrate is to sit on a rotating chair. The compass is not multi-positional. You have to hold it flat.
- There is also a red alarm LED (the circle below the face). I didn't see it mentioned in any description.
- I didn't see a countdown during the safety stop but I think it wasn't set right. I changed a setting and I'll see if it works next time.
- It comes with a band extension to fit around your wetsuit, that is not mentioned in the description.
- It also comes with a screen protector much like the Invisible Shield for cell phones. Easiest way to install is to get it fully wet under the faucet. Wet the DC too to make sure there's no dust and smudges.
- The displayed information is pretty straight forward and easy to see - tank pressure, depth, times, etc. Everything you need to know.
- There's a nice battery check function that checks the DC and transmitter. The only thing is that it does not give the battery status of the transmitter unless it's hooked up and pressurized on a tank. Perhaps they'll change it on a firmware update?
- I like the Oceanic download software better than the Cobalt. There is much more information you can keep track. You can add pictures from the dive into the logbook. You can also keep track of recurring information like equipment used and buddy information. If it's too confusing to change your settings on the DC, you can do it through the software.
- If you wear it as a watch, the numbers are nice and big. The temperature reading will be off since it's sitting next to your skin.
Overall, if you like gadgets and have patience, there's a good chance you'll like this computer. If you don't, you still might like it once you've figured it out. It has all the bells and whistles you can want on a DC (except for a GPS which no one has figured how to make work yet).
This is my second wrist computer and I absolutely love it, the size is the same as a normal watch which I really like. The buttons can be a little confusing at first but once you learn the button sequence for the menus it is really easy to navigate. It give you all the information you could need at any given time plus it comes with the pc cable to download you dive to your company outer for nice graphs and info.

Yes. I have my computer on metric system. It is a setting that is easy to change. Can also set pressure to Bar.

I am unable to connect interface cable to the OCi. I try to line up the red dot like it says and turn but it does not turn, lock or connect. It goes, what seems like all the way in with the dot lined up with the mark at 3:00 on the watch. What am I doing wrong? Help??
Robert J G
The owners manual has a typo....
It should be 11:00 position and click into 12:00 position.
The owners manual says 1:00

Hi Jay P. I had the similar problem e the solution is simple and I thought I was stupid for not thinking of it sooner. There's an O-Ring at the end of the connect cable to the watch. Take it of and plug the cable again and turn gently. You don't have to force it. It will appear a little loose but it does connect.

I had same problem, allign red dot with top dot. Push really hard and then twist. Ruber casket is hard to squish. Make sure the notches line up on the male and female side when dots are aligned. Hope this helps
JAY P
Thanks. I was a little leery about pushing but yeah - now it works. Thanks

How does the backlight work? Can one configure it so that it is always on? I need a computer that does not require for me to push a button for it to light up in semi-dark conditions. Thanks
ALAN F
For normal dive mode the backlight durations can be set to 5, 10, 30, or 60 seconds. you need to push a button to get it to light.
BRUCE H
Backlight works by pushing button, works ok but if left on would drain battery
Battery is replaceable however it is not recommended
CARL S
Below is how to adjust the back light. I do not think you can adjust it so it is always on, max is 60 seconds. The reason is it will drain the battery very quickly. I found that I am replacing my battery about every 9 months or less. If you set it so the back light is always on, it would drain much faster. Especially, if you forget to turn it off after a dive.
How to set the back light time is found on page 25 in the manual (you can download a PDF version from Oceanic online).
Hope this helps.

Does this come with anything that you wouldn't get buying the computer by itself (other than the transmitter)?
Dennis P
Nope. The only difference is the transmitter.
ERIK A
It comes with an extension for the wristband and a CD manual. Buy the transmitter, its worth the money. If not, get a compass and a cheap watch. Great unit, my wife is extremely happy with it.
TALAL D
No. It came with a usb cable, cd, and a bigger strap for dry suite wear. All of these items are good to have.
Hassan A
What does the item include?
Thomas W
Wrist computer, usb cable, transmitter, clear plastic protector for face of wrist computer, computer disc.
