Its sleek design and advanced features make it well-suited for those diving into underwater exploration. As the water warms, divers can rely on this water-resistant dive watch to navigate both saltwater and freshwater environments with ease. Designed for unisex adults, the Leonardo 2.0 is ideal for detailed dive planning with its customizable Air, Nitrox, and Gauge modes. With user-adjustable conservatism levels and a deep stop function, this dive watch provides precise control tailored to your diving conditions and experience level.

Compatible with iOS and Android devices, the Leonardo 2.0 enables seamless data logging and analysis via infrared and USB connectivity. This feature allows divers to review their dive data post-adventure, making it a tech-savvy choice for those who appreciate detailed insights. The watch is powered by a durable CR2430 battery, ensuring consistent performance with minimal need for replacements. Imported from Italy, the Cressi Leonardo is built to withstand the rigors of the underwater world, featuring a robust polycarbonate and Desmopan construction that is impact and scratch resistant. Its intuitive single-button interface makes mode selection and navigation straightforward, even for beginners. Whether using it as a sport watch, diving into the depths, or exploring new underwater terrains, this dive computer watch is a reliable companion, embodying Cressi's legacy of technical excellence and innovative design since 1946. From the Manufacturer An elegant expression of simple, functional design, the Leonardo 2.0 is a must-have for divers entering the sport and for those who "just want to dive". It is a completely modular, rugged computer with a wide UFDS display, which provides the proverbial ease of navigation and Cressi computer menus. It has complete Nitrox management, depth gauge mode, and a reset option. The algorithm incorporates RGBM and Deep Stop. Menus and navigation system identical to the rest of the Cressi diving computers, with ease of reading, access to information, and model parameter modification. A single-button interface makes it effortless to set Air, Nitrox, and Gauge modes the first time a diver picks the computer up, and an edge-to-edge, high-definition screen gives large numerical displays in a computer that is still compact and travel-friendly. Easy configuration, navigation through the various menus, and access to a large amount of information displayed intuitively. Features a “User-Friendly Display System”: the information display, screen contrast, proportions, and digit size have been carefully chosen for ease of use. All the information presented is separated by light lines to facilitate reading even in stressful or emergency situations. The back-lit display can be activated by a button or when the alarm sounds. Extended battery life through a combination of systems: battery saver mode when the computer is not used with automatic power-on. The clearly visible battery life indicator and distinct audible alarms deliver critical information as well as peace of mind during the dive. Gauge calibrated in salt water for maximum precision during typical use. The dive computer can be linked to a smartphone using the BT Interface (sold separately). It communicates with the dive computer via an IR connection. Use the Cressi app (available for Android and iOS) to download diving sessions and monitor training. The device is powered by a long-lasting CR2430 button battery which can be replaced by an authorized Cressi center by verifying perfect watertightness. The Leonardo can also be fully reset after each use, making it possible to give it to another diver. The Leonardo 2.0 is developed and made in Italy by Cressi, a brand pioneer in scuba diving, snorkeling, and freediving equipment. The product is covered by a 2-year limited warranty.

Review: Simple, reliable, capable, and affordable dive computer for recreational divers - This thing just works! It is one of only two computers I would recommend without reservation to occasional recreational divers like myself who dive only a few dozen times a year. It has a clear, easy to read display that tells you everything you need to know on one screen when you are diving. It allows you dive with Nitrox. The battery is easy to replace, and lasts a good while. The single button interface is actually very easy to use once you get the hang of it. Is there anything wrong with it? I wish the safety stop countdown included seconds to, not just minutes The backlight isn't the greatest, but I've never actually had trouble reading the screen on any dive. It also does not sync wirelessly to your phone or computer by itself. But at this price point, I honestly do not think you can find a better device. The Leonardo has become the backup computer to my Shearwater Peregrine over the years (the only other computer I would personally recommend without hesitation). The Leonardo matches the far more expensive and capable Shearwater device for accuracy and safety on all my dives. Given how stupidly difficult, expensive, and confusing dive watches can be, I wish someone had told me to just buy this watch when I started diving well over a decade ago! If you are a beginning recreational diver and don't want to spend a whole lot of money on a computer, get this one. If you can spend a little more, spring for a Shearwater.
Review: Reliable dive computer - Reliable, clear screen and easy to navigate. No problems using on multiple dives and the fast ascension warning beeps are clear. Only issue is that it's *large* and occasionally spins around my S/M wrist
