    This is the first computer that i had purchased and I still love it. For the time being i use it as a backup. I have a console with max depth and air pressure and a Suunto Vyper computer. I also wear a compass on my right wrist (D4 on my left wrist). I fins my self using the D4 and the compass on my wrists WAY more than the stuff in my console but i'm glad that i have them there as a backup.

    Moral of the story, D4 is easy to use, Accurate enough for all but tech diving, PERFECT for a backup and even as a primary with analogue gauges as backups.

    I bought the D4 as a replacement for my Mosquito. The D4 is a bit easier to use than the Mosquito. The Mosquito has 4 headings in the Mode menu: Time, Air, Set, Mem, while the D4 has Time, Dive, Mem. The submenus are the same for both watches, but I prefer the Set as a submenu of Time.

    The D4 is somewhat larger and the numbers are also bigger. Both are readable but I much prefer the smaller numbers of the Mosquito because of the contrast between the numbers and the background. The image on the Leisure Pro site is an accurate reflection of how the display looks so judge for yourself. Just on the basis of this, I would not recommend the D4.

    The battery of the D4 needs to be replaced by a technician. This may not be a hassle, but I really enjoyed being able to replace the battery in the Mosquito.

    In my tests, the D4 and Mosquito use identical algorithms for diving on air. I have not tested the Nitrox setting.

    I highly recommend the Digital Online class that is offered with the D4. This class is a very nice way to get acquainted with the D4.

        Comments about Suunto D4 Wrist Computer:

        Being an amateur diver, the Suunto D4 has all the features I`d ever need. The only thing I`d probably want would be wireless tank pressure gauge, but then I`d need the D9 and that is overkill for me. Very nice product, robust, bought it in the end of 2009 and to this day the battery is strong, after 15 dives or so.

          Comments about Suunto D4 Wrist Computer:

          This is a great secondary or primary computer. My primary went down and I needed another computer quick, most of my friends use a D4 or D4i so I grabbed one too. It was a little different using a wrist mount opposed to my usual gauge mount but the functions are great and it is really easy to use. The safety features are great. It provides all the information I need and then some. Gas switching is one of the most useful features I have found with this computer.

            Beware: No Average Depth in Logbook

            Comments about Suunto D4 Wrist Computer:

            All Suunto dive computers with dot matrix dive profile displays do not make average depth information available in the logbook. I found this out after I bought it because I assumed (wrongly) that the D4 would have, at least, all the features of the "lowly" Zoop available. Since I calculate my surface air consumption (SAC) rate after each dive, average depth is a critical part of my diving; and so I now just use the D4 as a wrist watch (it does look good) and dive with my cheaper Zoop, which does give average depth in the logbook.

              I bought the D4 as a replacement for my Mosquito. The D4 is a bit easier to use than the Mosquito. The Mosquito has 4 headings in the Mode menu: Time, Air, Set, Mem, while the D4 has Time, Dive, Mem. The submenus are the same for both watches, but I prefer the Set as a submenu of Time.

              The D4 is somewhat larger and the numbers are also bigger.

              Questions about this item:

              Shopper  Why Did You Choose This?
              BEN H  Easy to use, reliable, nice to have when you live on an island or near dive sites because you can wear it every day and always be ready for a dive. My wife rocks the Zoop and I also use a Sherwood Insight as a backup console unit but the D4i was my daily when I lived on an island.
              Shopper  What is the difference between Suunto D4 and D4i?
              MITCHELL D  From what I can tell the D4i is a newer version of the D4. It looks like it may have an optional wireless tank guage also .
              Hanns G  how big is the D4?
              JORGE M  The D4 and D6 are the same size. I had a D4 but now have a D6. The shape is nearly circular, with a diameter of 2 inches.
