Suunto D6i Review

Divers who share this will always see more fish in their dives

    Suunto is a trusted and respected dive computer producer.

    They produce high quality and durable dive computers with different designs and colors.

    Suunto has introduced the new Suunto D4i Novo that I have written a review about. You can read the Suunto D4i Novo review here.

    Today, I want to talk about another Suunto model: The Suunto D6i.


     

    Suunto D6i KitWith one sentence, I can tell you that Suunto D6i is for serious divers.

    There are four dive modes:

    1. Air
    2. Nitrox (you can use two mixtures, set their partial pressures -from 0.5 up to 1.6- and switch during the dive)
    3. Gauge (depth and bottom time is displayed without NDL calculations)
    4. Free Diving

    There are four operating modes:

    1. Time
    2. Dive
    3. Plan
    4. Memory

    Digital Compass & Wireless Air Integration

    Tilt compass helps you with the navigation. But remember to calibrate your Suunto D6i before you dive. Because this is a digital compass, you don’t have to hold your dive computer parallel to the surface/bottom like we do in traditional underwater compasses. Your wrist position doesn’t matter. It’ll work!

    Wireless air integration will work for both air and nitrox. You can see your remaining air pressure from your dive computer.

    Watch the videos below for how to pair with transmitter and how to calibrate your Suunto D6i

    Alarms

    There are a couple of alarms available in Suunto D6i.

    You can easily set a depth alarm if you want your Suunto D6i to notify you when you reach a certain depth.

    If you are planning to use a wireless air integration, you can set an “Air Alarm” that will help you know you have a certain amount of air/nitrox in your tank.

    There is also a “Dive Time Alarm.” You can set it from 1 up to 999 minutes. When your bottom time reaches, your dive computer will alert you.

    Free Diving Mode has two alarms as Surface Interval and Depth Notification alarms.

    Display

    If you are making a dry air dive, what you can see on your Suunto D6i’s screen is:

    • Current depth
    • No-Deco time
    • Ascent rate
    • Air information (if you are using a wireless air integration)

    You can simply push a button and also can see the following:

    • Water temperature
    • Maximum depth reached
    • Time
    • Dive time elapsed

    If you are making a nitrox dive, you can see all the information I have mentioned for an air dive, plus:

    • Current PO2 (partial pressure of O2)
    • FO2 set point (FO2: fraction of oxygen in the mixture)
    • O2 toxicity level in percentage

    You can adjust the brightness and the contrast of the display. This is not only for customization, but for battery life as well.

    Deco Mode

    Deco Mode is activated when you exceed the no decompression limits. Suunto D6i will display the required deep Suunto D6i Whitestops for you. If you miss any of them, your dive computer will get into an error mode and can only be used as a gauge for the next two days (48 hours from the time it gave the error).

    The Suunto D6i will “tell you” your next deep stop depth and time. It also calculates the time needed till you surface, assuming you’ll do all the deep stops guided.

    When a deep stop is over, your dive computer will show you the next required depth and time for the next deep stop.

    Dive Log

    Suunto D6i records up to 80 hours of your dives.

    You can select your sampling rate from 10 to 60 seconds. This means that you dive computer will save your depth in the interval you have selected.

    The “bookmarking” feature is a differentiation for Suunto D6i. You can “bookmark” a specific time or depth in your dive. You have seen a giant grouper? Bookmark it and never afraid to remember the time or depth when you surface!

    If you have a usb cable for your Suunto D6i, you can connect to your laptop and download all the information!

    You can see your dive as a graph. The frequency depends on your sampling rate. You can see the depth and time in the graph. If you are using a wireless air integration, you can even see your tank pressure and analyze your air consumption as well.

     Pros and Cons of Suunto D6i

    Suunto D6i Kit SteelI want to tell you some of the pros and cons of Suunto D6i dive computer as a result of my own experiences.

    Pros

    • Legible LCD screen
    • Stylish
    • Can also be used as a wrist watch
    • Planning and tracking your dives with Suunto DM4
    • Go online and share you dives via movescount.com
    • Nitrox modes and ability to switch during the dive
    • Wireless air integration possibility
    • Tilt compass included so you don’t have to carry a compass with you
    • RGBM – Full continuous decompression algorithm

    Cons

    • If you prefer to use Suunto D6i in Gauge Mode, you cannot use it in Dive Mode for 24 hours
    • You cannot replace the battery on your own
    • All the data is formatted when you send it for battery replacement, so you should download and save them in your computer if you’d like to see them again
    • Can be costly for shallow water or air-only divers because they will pay for the functions they won’t use
    • This can also be said in the pros section but the Suunto D6i is a little bit of conservative. This seems to be a con among the divers because it gives less bottom time and more surface intervals (I have also experienced less air pressure displayed as well), however it can also be seen as an advantage because it is safe

    Comparison with Similar Models

    I want to show you the differences between Suunto D6i, Suunto D6i Novo (new segment) and Suunto D4i Novo.

    This way, you can clearly see what their primary features are. And you understand what you are going to be paying for.

    Hope this comparison chart will help you making your decision.

    What Does Seaman Say?

    Suunto D6i is one of the leaders in the dive computer market.

    Its durability and conservatism make me advice you Suunto D6i without any hesitation.

    However, just like I have mentioned in the “cons” section of my Suunto D6i review, if you are a diver who

    • doesn’t make deep dives and as a result, doesn’t need a potential like Deco Mode
    • doesn’t like conservative dive computers despite more safety
    • makes 10-20 dives per year

    then Suunto D6i might be a little bit overdo and costly for you as a result.

      Comments

      1. Very well put together piece of advice, just the right amount of detail needed.
        Good one.

      2. I don’t suppose you have any feature comparison charts of the D6 -> D6i -> D6i Novo as well as the same for the D4 series? I’ve asked Suunto and they claim to not have (or publish at least) any such thing. It would be very helpful to understand the compelling improvements/changes between models to be able to choose the right one. Thanks.

      3. Thanks! That would be very cool. From what I can tell there doesn’t seem to be much (if any) difference between the D6i and the D6i Novo (except maybe the fancy colors to choose from) but it’s considerably more expensive. There are also reports that the compass on the D6i is much better than the one on the D6, but again, it’s difficult to know what the real story is behind each model and feature. And I can see why Suunto wouldn’t want to publish charts like this as it would probably hurt potential sales of new computers. Anyway, when do you think you might be able to put something together (call it expectations management 🙂

        Thanks a million!

        • Actually, with some work this information can be gleaned from the Suunto website. Unfortunately, it’s only possible to compare current models. So, it would still be nice to know how the D6i improves upon the “basic” D6 for instance. I’ll keep digging.
