Depth, Dive Time, and Decompression Monitoring

The Cressi Leonardo excels in monitoring crucial dive parameters, providing real-time data on depth, dive time, and decompression status. This dive computer accurately measures the diver’s current depth, allowing for precise navigation and awareness during the dive. Simultaneously, it tracks the elapsed dive time, ensuring the diver stays within planned limits. The Leonardo also continuously calculates decompression requirements based on the dive profile, providing essential information for safe ascent. This comprehensive monitoring system is crucial for divers to avoid decompression sickness. The computer employs the Cressi RGBM algorithm, which integrates the Haldane model with RGBM factors, enhancing the accuracy of its decompression calculations. The device presents this data on a clear display, enabling divers to monitor their dive status at a glance, supporting safe and enjoyable underwater exploration.

Ascent Rate and Surface Interval Display

The Cressi Leonardo dive computer provides crucial data regarding ascent rate and surface intervals, vital for safe diving practices. It continuously monitors the diver’s ascent speed, displaying it clearly to ensure a controlled and safe return to the surface. Exceeding the recommended ascent rate can increase the risk of decompression sickness, making this feature essential for diver safety. The computer also displays surface interval times between dives. This data is important for planning subsequent dives, as it affects the nitrogen loading in the diver’s body. The Leonardo’s surface interval display aids divers in avoiding repetitive dive risks by allowing them to keep track of the time spent at the surface. This ensures they allow for adequate off-gassing before their next immersion, promoting a safer overall diving experience. The clear display of both ascent rate and surface interval enhances the user’s ability to manage their dive profile.

Operation and Usage

The Cressi Leonardo is designed for ease of use with settings adjustable before diving. During the dive, it provides real-time data, and post-dive data analysis is available. Its single-button operation simplifies use.

Settings Before Diving

Before each dive, the Cressi Leonardo requires specific settings to be configured for optimal performance and safety. These settings typically involve selecting the appropriate dive mode, which could be air or nitrox, depending on the gas mixture being used. The user must also input the oxygen percentage if diving with nitrox to ensure correct decompression calculations. Additionally, you might need to set the desired conservatism level, which affects the algorithm’s decompression model, providing a more or less conservative approach based on your personal risk preferences. Furthermore, ensure that the unit is displaying in the correct units of measurement (metric or imperial) and that the battery level is adequate for the planned dive. The correct configuration of these settings before each dive is crucial for accurate data readings and safe diving practices. These initial steps are outlined in the manual for the Cressi Leonardo, ensuring divers can familiarize themselves with the proper setup procedure before entering the water.

Utilizing the Computer During a Dive

During a dive, the Cressi Leonardo continuously monitors and displays critical information to the diver. The primary display will show the current depth, the elapsed dive time, and the remaining no-decompression limit (NDL), if applicable. The computer also tracks the ascent rate, providing warnings if the diver ascends too quickly, which is vital for preventing decompression sickness. The display will show any necessary decompression stops and the required time at each stop, guiding the diver through a safe ascent. Throughout the dive, the diver should regularly check the computer display for any changes in the NDL, warnings, or decompression requirements. The single-button operation makes navigating through different displays straightforward, allowing divers to access all needed information during the underwater experience. The computer’s audible alarms also provide notifications that may require immediate action. It is essential for divers to be familiar with these displayed parameters to ensure a safe and enjoyable dive.
