Suunto Zoop Novo Diving Computer Lime

Wrist Mounted or Console Based Dive Computer?

The Zoop Novo comes as either wrist mounted or console based. Most new divers are heading down the path of wrist mounted dive computers.

The great advantage of wrist mounted is having the vital information on your arm where it’s easy to read, rather than tucked away on a console. If you’re going for wrist mounted, then the black rubber strap that comes with the Zoop Novo is long enough to go over your wet suit or dry suit.

Suunto Zoop Novo Bungee Adapter Kit

As an alternative to the rubber strap that comes with the Zoop Novo, Bungee Adapter Kits are available as an accessory. This come as either a basic bungee adapter, or with a mount boot.

How to set the Suunto Zoop to Nitrox

The 4 menu buttons make navigating and setting up the Zoop Novo very easy. The video below shows how how easy it is to set up for Nitrox diving.  

How big is the Zoop Novo?

There’s nothing small about the Zoop Novo.  It's been designed with both functionality and durability in mind. 

The screen is hard-wearing acrylic which will take the odd knock. Its display size is a good 1 ⅓ inches across (or 40 mm) making it easy to read at a glance, even for 'older eyes'.

The bezel diameter is 2.4 inches (61 mm) with a thickness of just over an inch, (28 mm). It weighs 4.23 oz (120 grams).  

Although the Suunto Zoop Novo is wrist mounted, it is not a regular watch-sized dive computer. It's far too big to be worn as an everyday watch.   


What Functions and Features does the Zoop Novo have?

You can’t overstate the peace of mind that comes with having an interface that’s easy to operate.

The Zoop Novo has some well thought out functionality. The Zoop Novo has a 4-button menu which are nice and big, making them easy to press. Menus are easy to navigate and the display is clear to read.

The ZOOP Novo is water-activated. You should to turn it on to Dive Mode before diving to do your pre-dive checks but if you forget, it automatically activates as soon as it goes deeper than 1½ feet (0.5 meters). The Zoop remains in Surface Mode at depths less than 4 feet (1.2 meters) and switches into Diving Mode at depths greater than this.

The standard dive alarms are all adjustable. A default setting will remind you to make a safety stop. Alarms can be set for maximum depth and dive time.

If you exceed the no-decompression limit on a dive, the Zoop Novo will provide the decompression information you need to make a safe ascent. After this, surface interval and repetition dive information will be displayed.

When switched on to dive mode, the battery indicator will show the current battery level. To conserve battery, the Zoop switches into its idle mode after about 3 minutes. During the idle mode it displays the current time, the day of the week, and the date.

It’s easy to set to either imperial or metric units (feet or meters, ºF or ºC) depending on your personal preference.

Diving at Altitude - No Fly Time

Traveling to a higher elevation will temporarily change the equilibrium of dissolved nitrogen in your body. It's generally recommended that you wait at least 3 hours before making a dive at a new altitude.

As with most dive computers, the Zoop Novo comes with an Altitude setting. This is not automatic, you need to adjust it yourself. 

When you adjust the Altitude, the Zoop Novo adjusts its mathematical model according to which altitude mode is selected. The Zoop Novo calculates shorter no-decompression times at higher altitudes

The no-fly time is shown in the center of the display next to an airplane icon. Flying or traveling to a higher altitude should be avoided at any time the Zoop Novo displays the no-flying time.

How long does the Zoop Novo battery last?

Life expectancy for the battery depends on the number of dives you have per year.

As a general rule, if you’re diving around 300 times a year, the battery will last between 8-12 months.  If you dive around 100 dives per year, you can expect to get about 12-18 months of battery life. Less than 100 dives per year, you should expect 18-24 months of life from the battery.  

Can I change the Zoop Novo battery myself?

The Zoop’s battery is a standard 3 volt CR2450.  There is the option to change this without having to send it away to an authorized dealer or take it to a dive shop.

If you decide to change the battery yourself, the Battery Replacement Kit can be purchased online. As well as a battery, the kit includes an O-ring and costs under $20.

Suunto Zoop Novo Battery Kit

The video below shows how to change the battery on the Suunto Zoop Novo and the Vyper Novo

It starts with a warning that changing the battery yourself or using an unauthorized dealer may void the warranty. If you can get past this, it then demonstrates how EASY it is to change the battery. The screwdriver size used is a T-6 torx.

If you don’t feel confident enough to change the battery yourself, then a new battery replacement can be included as part of the regular 2 yearly service by an authorized dealer.  

Which Algorithm does Suunto use?

The Suunto RGBM (Reduced Gradient Bubble Model) is a modern algorithm. The algorithm model monitors continuous multi-day diving and closely spaced repetitive diving. It also takes into account dives that are deeper than your previous dive.  

Adaptive Decompression

Some diving practices increase the risk of decompression sickness/illness. These include dives with short surface intervals, repetitive dives that are deeper than previous ones, multiple ascents, or substantial multi-day diving.

The Zoop Novo will adapt the decompression algorithm when any of these practices are detected, and in some circumstances will advise that your Surface Interval time needs to be extended. The ability to adapt to different situations and dive profiles provides added safety. It also changes these calculations according to any personal adjustment you select.  

Dive Planner and Logbook, Bookmarks and Memory

  • Dive Planner
  • bookmarks
  • log book

The Zoop Novo has a Dive Planner which is accessible by pressing the PLAN button on the front face of the computer anytime during Surface mode.

Here’s where you’ll find the calculator for a no-decompression stop. Using the two buttons on the bottom of the face, you can increase or decrease your Maximum Depth. Once you’ve made the adjustment, the Zoop will calculate your no-decompression time.

Higher altitudes and conservative personal adjustments will shorten the no-deco time limits. The Planning mode also takes into account the following information from previous dives:

  • arrow-right
    all dive history for the previous 4 days
  • arrow-right
    any calculated residual nitrogen
  • arrow-right
    oxygen toxicity (Nitrox mode)

The no-decompression times given for different depths will then be shorter than before your first ‘fresh’ dive.

Do I need to buy the USB Cable to download my Dive Log?

The USB cable is an optional accessory and is not included in the price of the Zoop Novo.  Buying the USB cable allows you to download your dive profile information to either a PC or MAC. 

The Suunto DM5 software is free to download from Suunto’s website.

What dive information is downloaded?

Once downloaded, reviewing the data is great for planning future dives, keeping records of your dive history, and for demonstration or educational purposes.

Complete logbook data can also be downloaded. Paper copies are then easy to print. The following data is recorded and downloaded:

  • dive number
  • angle-double-right
    dive entry time (in year, month, day and time)
  • angle-double-right
    altitude and personal adjustment settings
  • angle-double-right
    depth profile of the dive
  • angle-double-right
    dive time
  • angle-double-right
    oxygen percent setting and maximum OLF (in Nitrox mode)
  • tissue calculation data
  • the temperature at the maximum depth, beginning of the dive, and the end of the dive
  • angle-double-right
    surface interval time
  • angle-double-right
    identity number of the dive computer
  • angle-double-right
    additional dive information including personal information, and any SLOW and mandatory Safety Stop violations, Dive Attention Marks, Bookmarks, Surfaced Marks, Decompression Marks, and Ceiling Error Marks).

An alternative to this is Diveboard: Your Online Scuba Logbook. The crew at Diveboard have created a free program called Diveboard Agent. After downloading, this connects with many dive computers including the Suunto Zoop.

Sunnto and Diveboard have worked together to provide integration between Movescount to Diveboard. Another open-source option that’s worth looking at is Subsurface.

Functions that the Zoop Novo is missing

There's no doubt that Suunto’s Zoop Novo is an entry level dive computer that has all the functions beginner divers need. Below is a list of the features that the Zoop doesn't have that I'm sure you want to be aware of. I've also listed alternative dive computers to look into if one of these features is particularly important to you. 

Surface Interval - In comparison to other dive computers, the Zoop Novo has a longer Surface Interval time. A minimum of 5 minutes is needed between each dive. If the Surface Interval is shorter than 5 minutes, the Zoop Novo treats the next dive as a continuation of the previous dive.

No-Fly Icon not displayed when not turned on - The Zoop Novo does not display the no-fly icon when on standby. You need to activate it to check the airplane icon is not displayed before jumping on a plane.

No Digital Compass, Tri-mix or Air Integration - The Zoop Novo doesn’t have a digital compass, tri-mix capability or air-integration. Compasses are cheap and widely available, but if you’re after a built in compass and air integration, then have a look at the Suunto Vyper Novo

No Bluetooth Connectivity - Unlike the Cosmiq+ which has Bluetooth connectivity, you need to buy the USB cable to download your dive logs and update your firmware. Click here to read a review of the Deepblu Cosmiq+ Dive Computer and see the comparison tables against its rivals. 

Large Dive Computer - If you’re after a watch-sized dive computer, look into the Suunto D4i Novo, and Suunto D6i Novo. 

If you think you’ll expand on your training later on or are definitely headed towards more advanced recreational or technical diving, then take a look at the Shearwater Perdix or the Shearwater Teric.

What about the Price and Manufacturer's Warranty?

The Suunto Zoop Novo Dive Computer is well priced. You should be able to find it for between $280-$350 online. The USB cable needed to download the dive data to your laptop is around $70.  

The software is free to download. When the time comes to change the battery, the Battery Kit costs less than $20.

These come with a 2 year Manufacturer’s Warranty.

Servicing, general maintenance and things to avoid

As it’s always better to be safe and avoid problems before a dive trip, plan to have the computer serviced every couple of years, or after 200 dives. Its calibration will need to be checked, as well as a test of the functions and the waterproof seal.

To keep your Zoop Novo working well for years, always thoroughly rinse in fresh water after each dive. Make sure all salt crystals and sand grit are removed. It’s important that the water contacts/connector are kept clean. Clean with fresh water and a soft brush. Dry off and store in a cool, dry, well-ventilated place away from the damp. 

Regularly check the condition of the band, clasp and metal components. Over time these can become affected by a build up of sunscreen, perspiration and sea-salt.  

Protect the Zoop Novo from extreme heat, direct sunlight, and chemicals. Although well built, it won’t withstand the impact of heavy objects falling on it, such as Scuba tank cylinders.

The Conclusion?

The Suunto Zoop Novo has the functionality entry level divers need.  It’s easy to use and an excellent entry point computer for recreational divers.

It has good features at an excellent price. The Suunto Zoop Novo is a great choice for your first dive computer.  It’s even made our Best Dive Computer for 2018 list.
