  • If you are solely doing recreational diving, and only gonna wear a dive comp. during diving, i would say go with the Suunto Zoop. large and easy to read display, user changeable battery, and compatible with air and nitrox. more then sufficient for recreational diving.

    of course if you want a more stylish watch dive comp. then the Suunto D4i would be next. And if you have the cash to spare, than the Suunto D6i.

    If you're thinking of maybe going into tech in the future, then i would recommend the Shearwater Petrel. And if you have more cash to spare, than the Liquivision X1!!! hahaha! :P

  • Hi there,

    I'm planning to do my Advance next year during Adex fair  :D

    I heard Zuunto  not ideal for Nitrox because it does not show how much Nitrogen 'left to use'. For example, like it does not show how much gas is left in the tank of the vehicle.

    Haha not very good at explaining  :P

  • as long as the computer covers recreational nitrox you should be fine.

    the  suunto zoop does both air and nitrox. essentially the difference between air and nitrox modes allows you to change the amount of O2 (oxygen) in your air(21% O2) mix, nitrox commonly can be 32-36% O2. most recreational computers today will handle up to 40% O2 as will properly O2/nitrox capable sanitized regulators.

    the effect of nitrox is longer bottom times at restricted depths, beware use of 02 rich nitrox imposes depth limits around the mid 30m range due to O2 toxicity at depth. refer to nitrox tables and computer for details.

    good luck on purchase and the zoop is a fine starter computer.
    stuff from aeris/oceanic is cheap and ok too, as is the basic mares models.

    I prefer the uwatec/subgear models... though they are a bit more expensive. I have found them more adaptive to my diving profiles.

    the shearwater and liquivision stuff is good gear from wat I can see, but is a bit pricey for me.

    cheers, TM :)

    haha! not too sure what you mean, but like most other computers, the Zoop does show you the No Decompression/Stop Limit when diving. Basically the computer algorithm calculates how much Nitrogen your body has absorb base on how many previous dives you have done, their depths, dive times and surface intervals in between. It then tells you how much more time you have at each depth before you go into deco.

    If i'm following your gas in car tank analogy, it would relate more to monitoring how much air is left to dive with. U would probably then need an air-intergrated computer like the Suunto D-series, and a transmitter. This will monitor how much air is left in your tanks and tell you exactly how long more you can stay underwater base on your current breathing rate. i.e. like how long more can you drive before you run out of gas base on your current miles/km per gallon consumption rate in a car.

    Hmm... the prices for AOW course at ADEX these days are usually not much different compared to normal rates... Unless you are going for those 'mass factory' schools...
    Here's my suggestion... why not use the money now to go for a good AOW first...
    Then when ADEX comes... look for a good deal on dive computers?  ;)

    a Suunto Zoop/Mares Puck/Oceanic Geo is really good enough for any recreational diver...
    If you are into the aesthetics and have the spare cash, then probably a Suunto D4i...

    All you really need is just No Deco Time/Depth/Safety Stop timing and probably an ascent alarm...
    If all these terms don't make sense to you, then you've gotta research alittle bit more :)

    Integrated Air Wireless Transmitter?... These gimmicks & frills still do not have my confidence yet and reliability is still a big question mark for most people...
    Besides, adding that would incurred more cost when you need to service + change battery....
    I still feel that the good'O SPG is still the most reliable & cost effective way to read my tank pressure...
    Ask any Tech diver... and they will tell you the same thing too...  ;)

    Live, Love & Dive...

  • i'm a fellow newbie to diving and i tell ya, better go to the store to look at the watches.
    1. the buttons used to navigate the settings, one or two or more? easy to navigate through the settings?
    2. preferred size of dive com. suunto zoop has a big face, so does the cressi leonardo/giotto. or do u prefer a 'watch' size face like the suunto D4i or D6?
    3. are you a guy or girl? if u have very small wrist, you'll notice you need to put to the last few holes of the watch, leaving a very long strap dangling. this is common for zoop/leonardo. u can find fellow divers to see which watches can change strap. D4i/D6 its a 'watch' u can wear daily the straps are like watches.
    4. do you want a watch with Hot swap battery or non-hot swap battery? as in, able to change battery on your own like oceanic geo? cos suunto not all have swapable batteries, have to bring to retailer to do.
    5. do you want to be able to upload the dive log to your computer? some of the watches have this function, buy the usb cable e.g. d4i/d6
    6. Nitrox/Air/Gauge/freedive modes. most dive comps now have nitrox & air modes. you may want to consider gauge mode. this is for situations where you want to follow your own dive plan, don't want to use the dive comp cos its too conservative and it'll beep like mad when you exceed their recommended dive time, depth and so u turn on gauge mode to only use the watch to measure depth and timer.
    7. does the dive comp have a easy to turn on 'light' for when u're doing night dives and want to check the depth, don't need to shine the torch on it (i am not sure if all dive comps have this)

    i like this site for the reviews. http://www.dive-computer-wizard.com/

  • HI All,

    Thank you for your advices :)  :) :)

    Understood most of the diving language but can I check what does it mean by conservative in dive watch ?

  • To maybe put it simply, conservative dive comps is one that adds in a substantial safety buffer to the actual theoretical value, to keep you on a safer side.

    A hypothetical example, if you could stay at 20m for a theoretical no stop/decompression limit of 30mins, the computer might display 25mins instead. So if you follow the computer strictly, you'll never dive to the limit, reducing the possibility of complications compulsory decompression stop or worse DCS.

    I don't think a dive watch can be conservative or not, as they basically only shop time and depth, and does not compute ascend rates or no stop/decompression limits.

  • Hi CLoudBerrie,

    Is there any setting to change/ alter the conservative range ?   :)
