Suunto Zoop Novo Dive Computers

Product Information

Though not recommended, you may break (ignore) deepstops and safety stops. Suunto Zoop Novo penalizes such actions with additional stops or other measures, either during the dive or on following dives. For more information, see Safety stops and deepstops. The blinking ASC TIME text and an upward arrow indicate that you are below the floor. A low priority alarm will also sound. You should start your ascent immediately. The ceiling depth is shown on the left side of the center field, and the minimum total ascent time on the right side. At first glance, it’s easy to think there’s not much separating these two. Both have nice big displays and offer similar functionality. Looking closer, the main difference is how you access these functions. The Zoop Novo has four navigation buttons while the Leonardo has just one. Suunto and Cressi both use their own RGBM (reduced gradient bubble model) for calculations. Suunto’s comes in on the conservative side while Cressi’s is slightly more liberal. Which model is better? The Leonardo may give you a tiny amount of extra bottom time but there’s not much to really tell them apart. For an entry-level dive computer, the Zoop Novo boasts a large logbook memory and can store up to 140 hours of data (approximately 100 dives). However, in freediving mode, this reduces to 35 hours.

There are different tones to indicate high and low priority. High priority alarms will sound if the decompression ceiling depth is exceeded, the current depth is too deep for the gas mix in use, or if you’re exceeding the maximum ascent rate (10m/32ft per minute). Whether scuba diving or freediving, the low priority alarm will sound when you reach the defined maximum depth. Logbook Memory Before you do a decompression dive, you need to understand the meaning of ceiling, ceiling zone, floor, and decompression range. You need to understand these concepts to be able to correctly interpret the guidance provided by the dive computer. The Zoop Novo also allows you to change the altitude setting which will adjust the computer’s decompression calculations. The default is 0-300m/0-980ft and can be changed to 300-1500m/980-4900ft or 1500-3000m/4900-9800ft.

Each approach has its pros and cons. With a single button, you’re not going to get confused about which to press. But we found it tiresome having to navigate through so many menus just to find the item we needed. The Leonardo allows you to easily reset the computer, wiping the memory. This is a great feature for dive centers and schools; each new diver can start fresh. However, we found that if you’re using it as a personal computer, it’s not a function you would use at all.

The decompression range is the depth range between the ceiling and floor. Within this range, decompression takes place. However, it is important to remember that the decompression slower at or close to the floor compared to the ceiling zone. Suunto uses its own customized RGBM model which was developed in collaboration with Dr. Bruce Wienke. Unlike the classic Haldane models still used in some dive computers, the Suunto RGBM predicts free gas as well as dissolved gas in the tissue of divers. When you reach the ceiling zone, the display will show you two arrows pointing at each other as shown below.The Zoop Novo computer includes full decompression capabilities, five dive modes (Air, Nitrox, Gauge, Free and Off) and straight-forward, menu-based Suunto user interface. Suunto Zoop Novo Dive Computer – Features

Display information on the Zoop Novo can be shown in metric or imperial, and Fahrenheit or Celsius. Nitrox Compatible One change Suunto has made to the original Zoop is to add a fourth button to the Novo for easier navigation. You have mode, select, up, and down, all clearly marked, and with the large display, it’s super easy to navigate through the menus to find what you’re looking for. This offer excludes large items (Kayaks, SUP,canoes, waterski’s) and hazardous products, lift rafts, distress flares, electronics. There are many audible alarms on the Zoop Novo to let you know when important limits are being reached or passed. This doesn’t mean it’s going to be beeping at you every two minutes though. By monitoring repetitive dives, reverse profiling, short surface intervals, and multi-day diving, the Zoop Novo’s decompression algorithm adapts its calculations to take all these practices into consideration.Adjusting the computer to dive on Nitrox is easy. In Nitrox mode, you enter both the percentage of oxygen being used and the ppO2 (oxygen partial pressure) limit. It’s programmable for 21% to 50% oxygen mixtures and adjusts between 1.2 and 1.6 bar (17.4 to 23.2 psi) ppO2. Audible Alarms In other words, rather than requiring you to make stops at fixed depths, the dive computer lets you decompress within a range of depths. This is known as continuous decompression. Ceiling, ceiling zone, floor and decompression range The ceiling zone is the optimum decompression depth range. It is the range between the ceiling depth and 1.2 m (4 ft) below that ceiling. However, it’s important to note that any “user errors” when replacing the battery (such as a dirty seal or a battery compartment not closed correctly) will void the warranty. If you’re not confident about changing it yourself, you can always get the battery changed as part of the computers regular two-year service. During the decompression stop, your total ascent time continues to count down towards zero. If the ceiling moves upwards, you can ascend to the new ceiling.

You may surface only after ASC TIME and CEILING have disappeared. This means that the decompression stop and any mandatory safety stop have been completed. As we all know, there are a number of factors that can increase your risk of DCS. If you’re diving and you know you carry certain DCS risk factors (age, obesity, circulatory issues), the Zoop Novo allows you to adjust the algorithm to be more conservative, providing an extra level of safety. Obviously, if you are exceeding the NDL and your dive becomes a decompression dive, the Suunto RGBM penalizes you with extended surface intervals and any subsequent dives will be impacted. Be aware that this is a recreational computer. It is NOT designed for use on planned decompression dives. If you are intending to go into decompression it can be put into gauge mode and used as a bottom timer along with your dive plan. When conditions are rough, it may be difficult to maintain a constant depth near the surface. In such cases, it is more manageable to maintain a depth somewhat below the ceiling, to ensure that the waves do not lift you above the ceiling. Suunto recommends that you decompress deeper than 4 m (13 ft), even if the indicated ceiling is shallower. Ascent timeThe ascent time shown on your dive computer is the minimum amount of time needed to reach the surface on a decompression dive. This includes: The floor is the deepest depth at which the decompression stop time does not increase. Decompression starts when you pass this depth during your ascent.
