Questions & Answers

STEPHEN A C : Whare are the dimensions of the watch? Thickness and watch face size?JOE S : 2" Diameter and 5/8" thick
PATRICK D : Does it come with a transmitter?JOE S : It does not.ANDERSON M : No. This is a low quality product, and I highly doubt the transmitter would work, at least not for long. If you are diving once a year on vacation, though, then this might be worth considering (not for diving frequently for work, like me, in which it has crapped out repeatedly, including once due to the pressure change on an airplane!). I would shop for another computer, perhaps a Shearwater.JAMES P : no, unless you buy a package deal. The transmitter costs $350 to $400, when purchased separately.NICK D : No, you have to buy the package that includes the transmitterCuong N : No it does not. You have to buy one if you do not have one already.Andrew M : No. You have to buy it separate
Shopper : Is the light a blue glow, a green glow or a lightbulb? How easy is it to see on a night dive?NICK D : Light is green, Easy to see at night, works great.ANDERSON M : It is not easy to see at all. I can't even see it at dusk in a swimming pool! Moreover, do yourself a favor and do NOT buy this computer, especially if you are a serious diver. I am a diving professional, and it's broken 3-4 times since I've bought it. Oceanic only deals through distributors, so it's a 9-month turn-around to get anything, however trivial fixed. If you are just diving a few days a year on vacation, though, this might fit the bill.JOE S : Green Indiglow. Fairly easy to see.
WILLIAM S : Does this OCi have water temperature and outside of the water ambient temperature readings?JOE S : It will show whatever ambient temperature you are in. The temperature will switch back to air temperature after it leaves dive mode and will update temperature in dive mode each time it takes a sample for the log. You can change the sample rate.NICK D : YesANTHONY T : Yes, in the dive log it will record the water temp, out of the water it will show air temp.CHRISTOPHER L : Yes but in-water temp is inaccurate and I have had two versions of the OCI computer. Other functions work well.ANDERSON M : Yes, but there is a long lag time. For instance, if you go from outside at 90F to inside at 70F, it may not register it for 4-5 minutes. PS: don't buy this computer; I dive regularly and it has broken 2-3 times in two years. It has been under repair more than it has been in use (since Oceanic takes months to repair things).
Shopper : How easy is it to calibrate the compass and set the declination? Does the compass auto compensate for tilt? I do a lot of low to no viz diving and need very reliable nav gear.JOHN A : The Compass sucks. Don't tilt it. I purchased a separate compass on a retractor. Calibration failed just before a dive this past weekend. I miss my console computer with a mouned compass. All data there when you need it.JOE S : The calibration is simple by following the instructions to hold it certain ways until you hear a beep. The declination is in the compass settings and can be added in the same as setting the other features. The tilt is around 90 degrees.

Thank you

The watch I ordered arrived but did not work. Scuba.com was quick to reply to my emails and when I notified them that we replaced the battery and now it works, they graciously mailed out a new battery on their own. So thank you Scuba.com

Oceanic OCi dive computer

It is great diversified function dive comp. Reason I put 3 stars is the battery life is too short and almost every 6 month I need to replace it.

Good dive watch…a bit tough to learn

Great watch. It was a bit hard to learn, and the display is not bright enough for swim throughs…but certainly does the job. The watch lost contact with the tank transmitter halfway through my night dive…not sure why. But that wasn’t very comfortable.

NO customer service support from Oceanic/Huish

I have left two messages with Oceanic/Huish customer support and they have never called me back. I will never buy an another Huish product again. I work at a college that the majority of their equipment is Oceanic and they can't find any customer support or service. My next computer will be a Mares from a local dealer.

Avoid- poor poor quality

Bought two of these for my wife and I with air integration. Just came back from using them for the first time in Turks & Caicos on the Aggressor liveaboard. Both computers froze up, mine after 18, my wife at 15. Total junk.......had a Veo previously and it worked flawlessly for years. Avoid the OC...get a Shearwater, comparable price, much better quality...waiting for mine to be delivered.I

Leaked after 10 dives.

When my beloved Suunto D4 was lost at sea, I was in the market for a new dive computer, and I wanted one that could be worn as a watch since I wanted to use the timer for swimming laps. I also liked the digital compass feature since I am a marine biologist. As only my third ever dive computer over 20 years of diving, I was expecting this one to last about 10 years, ideally more. Instead, it leaked after 10 dives. I may have gone to 120 ft max., but certainly it's rated for deeper. Had that happened after 10 years, I wouldn't gripe, but considering it was only a few months old, I was incredibly disappointed. LeisurePro forced Oceanic to swap it out (they didn't want to, but it was under warranty). I thought Oceanic was the rich man's dive company?? Maybe I am living in the past!

Awesome dive watch computer, but it flooed and Leisure Pro is not supporting product.

love every aspect of this Oceanic OCI Blackout dive watch computer so far except that it flooded on my first open water dive. I called leisure pro regarding my Oceanic OCI Blackout dive computer flooding on my first open water dive. I live in Michigan and this is the first opportunity I had to use my dive computer for the scuba diving season. Leisure Pro said that they could do nothing for me. Since I used my dive computer, it is not considered new, but used. I explained to them that this was my first dive of the scuba season, and that it's a defective product that flooded on my first dive. Leisure Pro reiterated to me, since you took the dive computer under water, it is no longer new!!! That I now must go through the manufacture warranty process. My issue with Leisure Pro now is, how does a customer know if a product is working properly or if it's defective in scuba diving, if you don't take it under the water. I'm very disappointed in Leisure Pro with how they treat their customers. I purchased a high end dive computer through Leisure Pro and now I have to wait 5-7 weeks before I can get my dive computer back. That was the earliest I was told I could get it back. Now my scuba diving season is ruined because I purchased an expensive high end dive computer through Leisure Pro and I have nothing to show for it, but a defective product. I understand there will be issues with new products and some growing pains that occurs along the way, I'm sure Oceanic will make this right.... But I caution anyone buying from Leisure Pro to think twice. If I purchased this dive computer from my local dive shop, they would have replaced the defective dive computer with a new dive computer and made the purchase right!!! My mistake was trying to save a little $$, which now was a big mistake because Leisure Pro does not support the products they sell. They make you go through the warranty process. I understand and completely agree with going through the warranty process if I used the dive computer for months and it flooded or became defective, but this was my first open water dive. First time under water at depth and $1299 lost for the 2016 scuba diving season. Thanks for nothing Leisure Pro!!! I will never purchase another item through Leisure Pro, buy from your local dive shop, they will take care of you and your scuba diving needs. The watch is very stylish and I love the look as a normal watch. I loved the air integration aspect during my first open water dive, it never missed a beat. I always had access to the amount of air I had left in my tank. I love being able to see how much time I have left in minutes before I used up all my air. I love how I can gage my SAC rate using this awesome dive computer. This watch has everything you could ask for in a dive computer and than some. The information is easy to read, and easy to access. The compass is great to use and accurate. It does a great job counting down your safety stop, does a great job providing your ascent rate and you NDL. Anyone looking for a dive watch computer will love all aspects of the Oceanic OCI Blackout dive computer watch. So the functionality of this computer, the cosmetics and ease of use is 5 stars in my book. I just wish it didn't flood on my first open water dive and that Leisure Pro supported and assisted their customers with defective products that they sell. Pay a little more for the support your local dive shop offers. You won't regret buying from the local dive shop. I regret purchasing the Oceanic Blackout dive computer from Leisure Pro, no support from Leisure Pro, now that they have my money. Leisure Pro you lost a customer for life!!! Sent from my iPhone

Best computer i have used in 39 years of diving

As a professional diver I expect a lot out of my gear. I am in the water more than out from March through December each year and spend the majority of my dive time as an instructor, divemaster or spearfishing guide in the northern gulf of Mexico. This is the only time I have had a computer that could do it all for me on my dives. The signal from computer to transceiver stays strong, the display is incredibly easy to read, and the compass works flawlessly. I have owned other computers but nothing that comes near to the OCI in performance as well as the bang you get from your buck. You will not be disappointed with this product.

Computer is nice and small, looks great. Buttons and menu are easy to figure out and set up. Works great with wireless transmitter. All in all I'm very happy with the watch/ computer so far. Would for sure recommend.

Recommended with reservations

It's a really great computer when it works. I have two of them and both are back at Oceanic for repair. One looks like it has a bad pressure sensor and the other is "stuck" on the compass calibration screen. The good thing is that customer service at Oceanic is top-notch. I got a replacement for one within 7 days of return. I like it a lot, but if you're going on vacation with it, take a backup until you are sure you didn't get one with issues.

Looks Great. Excited

Just received this a couple of weeks ago but haven't been out with it yet. Excited to get going with it. Very stylish. Had to replace yet another flooded Manta so looking forward to this.

Oceanic OCi

By SHAUNA L.

Fantastic computer, all the bells and whistles!

Introducing the OCi for the diver that wants it all, Oceanic means that literally. The OCi represents the next step forward in recreational wireless air-integrated (optional see Transmitter SKU: OCNATT) dive computers from Oceanic. They combined the technology of their advanced OC1, the styling of the bestselling OCS and some new features into one incredibly capable dive computer. The "i" stands for Incredible. The Oceanic OCi is an advanced all-in-one dive computer featuring Oceanic's exclusive Dual Algorithm, wireless air-integration, digital compass, and so much more. All in a strong, lightweight housing, not only is the OCi powered by Oceanic's ground breaking dual algorithm technology but it can handle up to 4 gases, calculate nitrogen during a free dive (in the new tech free mode), enable you to select between salt or fresh water and it even automatically adjusts your altitude. The customizable alarms and digital compass are just icing on the cake. Oh, and let us not forget that it functions pretty well as a watch too. Feature for feature the OCi has no competition.

The OCi Computer is powered by Oceanic's Exclusive Dual Algorithm - Your choice between Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis). The computer has a 495' (150m) depth rating with advanced digital compass that provides north, reference, auto home, and declination adjustment (see NOAA's NGDC geomagnetic chart) and can switch between 4-independent transmitters (with optional see Transmitter SKU: OCNATT), with up to 4-Nitrox mixes to 100% O2 will meet all your today diving needs and those in the future!

No need to stow it in your gear bag while traveling or every day for that matter. The computers advanced watch functions including alternate time zone, stopwatch, lap timer, daily alarm, and countdown timer. You may never want to take it off! When diving the computer has deep stop with countdown timer, gauge mode with run-timer, watch, norm (Air/Nitrox) gauge, free dive, and tech free dive modes of operation. The computer is water or push button activated. Want to customize your own safety factors? The OCi Computer provides personal conservative factor adjustments (PCFA). Each level of the PCFA provides no decompression limits for the next dive +3,000' (920m) altitude adjustment.

The computers altitude algorithm is based on the NOAA model and provide altitude adjustability from 2,000' to 14,000' (610m to 4,200m). The computer has an operational (Gauge/Free Dive Modes) depth of 495' (150m) with a (NORM Mode) depth of 330' (100m). When in low light conditions the OCi is equipped with Ocean-Glo backlight with an adjustable duration function. The computer is powered by a CR2450 lithium battery that can provide up to 300-dive hours. The computer allows battery hot swap to retain dive data along with a graphic low battery indicator.

With the optional transmitter (see SKU: OCNATT) you will be able to take advantage of all the wire-less air integrated functions of the OCi computer. When coupled with the transmitter the OCi provides the following unique features:
Air Time Remaining:
The Air Time Remaining feature calculates current depth, tank pressure, breathing rate, ascent time, and decompression status to tell exactly how much time you can remain underwater. The OCi Dive Computer continually displays air-time remaining via a numerical bar graph in addition to cylinder pressure. You may also display air-time remaining in oversized digits at any time with the press of a button.

Dive Time Remaining:
Dive Time Remaining, like Air Time Remaining provides a Real" number in minutes. This calculation combines Air Time Remaining, nitrogen and oxygen absorption, displaying whichever allows less time. The OCi features push-button or automatic activation, triggered by water contact. A benefit of push button activation is easily verifying operation and cylinder pressure (if coupled with transmitter), but in case you forget, or simply choose not to activate your computer, it can be as simple as jumping in the water.

Other features of the OCi Computer are alarm acknowledgment (u/w de-activation), ascent rate range, accent rate maximum, decompression capacity of 10' to 60' (3m to 18m), deep stop function, automatic safety stop prompt, audible alarms, calendar/clock, 24 hour time to fly countdown, calculated de-saturation fly countdown, dive mode displays, high O2 and PO2 alarm/warnings, 24 dive on-board log capacity, temperature display, nitrogen and oxygen tissue loading and loading bar graphs, no decompression time remaining, O2 time remaining, variable ascent rate bar graph, set maximum depth alarm, FO2 value (%) for 4 gases, maximum PO2 alarm, free dive settings, unit of measurement setting and much more. The OCi Computer comes with a USB cable, Oceanic Ocean Log PC/MAC download, and PC setting upload, durable wrist band with extender, user upgradeable firmware and digital online class.
