The Cressi Donatello has a pretty straightforward design without nonsense. It’s the minimalistic of the Cressi bunch. Leonardo is the battle-proven dive computer and it has gone through extensive operation by users all over the world. Meanwhile, Donatello, although popular in its right, hasn’t gone through the same scrutiny. The Cressi RGBM algorithm is an adaptation of Suunto’s model, which has a reputation for being quite conservative. Cressi’s algorithm is based on a nine tissue compartment model using saturation half-times between 2.5 and 480 minutes. It allows for safe decompression calculations for repetitive dives over multiple days. As we looked at above, users can adjust the level of conservatism should they wish. They can also add or remove deep and safety stops. What Does This Mean for the Diver? The Donatello has the capability that you can switch the dive computer functionalities off even if you are in the water. The ability to swim and snorkel without dive calculations is a great new feature. You can deactivate the dive computer functionality, which makes it possible to use the watch for any kind of water activity, like snorkeling, without switching decompression calculations on and confusing the dive computer.

Overall, the Cressi Donatello is an improvement over the Leonardo ( Cressi Leonardo vs. Suunto Zoop Novo). It would make sense that the Leonardo gets cheaper and the Donatello will take over the price category that it was in for years. If you want to spend less money and don’t care about features like Bluetooth, you find yourself a good deal on the Leonardo and go diving. Overall quality of dive data display, including selection, layout and presentation of data, with a focus on how clearly it presents critical dive information See the watch clearer than before. Also, on the constant alarms, which divers find annoying, you can now switch off alarms. If you don’t want to switch off alarms because of safety fears, you can adjust the alarms to when you want them to beep.The Donatello gives several different and distinct audible and visual alarms to inform you of vital information while diving. A maximum depth alarm can be set by the user and the safety stop alarm reminds divers to make a stop before the last ascent to the surface.

Low relief profile with ergonomic design to properly fit the wrist and allow free movement of the hand There are also a number of alerts that warn you when you have exceeded limits, including PPO2 violation and ascent speed. Air is the equivalent of setting Nitrox to 21% and a ppO 2 max of 1.2 bar. When selecting Nitrox, you are taken to a submenu in which you can define the percentage of oxygen in the mixture (O 2%) and the maximum value of oxygen partial pressure (ppO 2 max) for up to three breathing mixes. The maximum possible value for the ppO 2 max is 1.6 bar. The PO 2 is set by the manufacturer to the default value of 1.4 bar, for both air dives and Nitrox dives.In addition to diving on air, the Donatello gives you the option of using enriched air. As it’s geared to recreational divers, the options are basic but do allow you to have one Nitrox mix up to 50% oxygen. To ensure you stay well within the safety margins regarding oxygen toxicity, you can also adjust the PPO2 (partial pressure of oxygen) levels between 1.2 and 1.6 bar (17.4 to 23.2 psi). Not all dive computers come with a compass, but they are good to help you with a sense of direction when diving Q: When using a dive computer, I should ascend (go up) at a rate not faster than?

From afar they both look the same although it should be pointed out that the Cressi Donatello has a more minimalistic approach to the overall design and Leonardo, on the other hand, offers you the greater aesthetic choice to personalize it. The Cressi Leonardo dive computer has a single button for navigation. As a result of this, the interface is incredibly easy to understand. If you are a beginner looking to start a diving career, you should consider this elegant watch. It has a decent dive log which can save more than 72 hours of data. It also comes in a console if you don’t like watch-style dive computers. The Donatello lets you adjust the algorithm to make it more conservative if you’re at a heightened risk of DCS. If you’re feeling stressed or dehydrated or diving in colder waters, you can change the safety factor and add an additional layer of safety to your dive. During the warranty period, Cressi or a registered dealer will repair any defects relating to the design or workmanship of the Donatello or replace it free-of-charge. Mares Quad has four navigation buttons on the side and is visibly labelled. In addition, the Mares Quad dive computer comes with a large screen and displays data prominently. Product ReviewWe are going to compare between some dive computers. Extra or missing features are compared between them to understand the differences. After all, maybe one of these dive computers has something that’ll come in handy, unlike the previous model. Cressi Donatello VS Cressi Leonardo. Cressi Donatello VS Cressi Leonardo
