RGBM Algorithm and Its Benefits
The Cressi Leonardo utilizes an advanced RGBM (Reduced Gradient Bubble Model) algorithm, developed in collaboration with Dr. Bruce Wienke. This algorithm enhances safety by providing precise calculations for decompression stops and ascent rates, reducing the risk of decompression sickness. It also allows for safer repetitive dives by efficiently managing gas saturation in tissues. The RGBM algorithm ensures a more gradual and safer ascent, adapting to individual diver profiles. This technology, combined with user-friendly operation, makes the Leonardo an ideal choice for divers seeking reliability and efficiency in various diving conditions, from recreational to technical dives.
Dive Modes: Air, Nitrox, and Gauge
The Cressi Leonardo offers three primary dive modes to cater to different diving needs. The Air mode is ideal for dives using standard breathing gas, providing essential data like depth, time, and decompression information. Nitrox mode allows divers to use enriched air mixes, extending bottom times and reducing fatigue. The Gauge mode operates as a depth gauge and timer, suitable for technical divers who prefer a simplified display. Each mode is designed to enhance safety and efficiency, offering personalized options for divers of all skill levels. This versatility ensures the Leonardo adapts seamlessly to various diving scenarios, making it a reliable companion for any underwater adventure.
Dive History and Desaturation Reset
The Cressi Leonardo stores a detailed dive history, allowing you to review past dives, including depth, duration, and ascent rates. This feature is invaluable for tracking progress and planning future dives. Additionally, the desaturation reset option enables divers to clear the computer’s memory of previous dives, ensuring accurate calculations for subsequent dives. This function is particularly useful on multi-dive trips or when changing environments. By maintaining an accurate dive history and allowing resets, the Leonardo ensures precise performance, adapting to the diver’s needs for safe and efficient underwater experiences. This feature enhances safety and personalization, making it a standout in dive computer technology.

Operating the Cressi Leonardo
Activate the device with a single button press, then navigate through modes like Air, Nitrox, or Gauge. The display shows real-time depth, time, and ascent data, guiding safe dives. Always follow the manual for proper operation.
Pre-Dive Checks and Preparation
Begin by ensuring the device is fully charged and all settings match your dive plan. Verify mode selection (Air, Nitrox, or Gauge) and review safety parameters like maximum depth and ascent rates. Check the battery level and ensure the display is clear for easy readability underwater. Familiarize yourself with the single-button navigation to avoid confusion during the dive. Perform a quick system check to confirm proper function. Finally, secure the device to your wrist or dive gear, ensuring it won’t obstruct your movement. Proper preparation ensures a safe and enjoyable diving experience with the Cressi Leonardo.
Using the Computer During a Dive
During the dive, the Cressi Leonardo provides real-time data on depth, time, and ascent rates. The clear display ensures easy readability, even in low-light conditions. Monitor your no-decompression limits and decompression stops as the computer calculates safe ascent procedures. Use the single-button navigation to scroll through data screens without interrupting your dive flow. The computer alerts you with audible and visual signals for critical information, such as exceeding safe depth or rapid ascent. Stay informed and in control throughout your dive with the Leonardo’s intuitive interface, ensuring a safe and enjoyable underwater experience.
Safety Guidelines and Precautions
Always follow decompression stops and ascent rates as indicated by the computer. Never exceed safe depth limits or ignore audible/visual alerts to ensure a safe diving experience.
Decompression Stops and Ascent Rates
The Cressi Leonardo calculates decompression stops based on the RGBM algorithm, ensuring safe ascent rates. Divers must adhere to these stops to avoid decompression sickness. The computer alerts when a mandatory stop is required, and the ascent rate should not exceed 10 meters per minute. Ignoring these guidelines can lead to serious health risks. Always monitor the display for stop depth and time, and adjust your ascent accordingly. Proper adherence ensures a safe and enjoyable dive, preventing potential decompression-related complications.
Emergency Procedures
In case of an emergency, the Cressi Leonardo provides critical alerts to ensure diver safety. The device alerts for rapid ascent, excessive depth, or decompression sickness risks. If an emergency arises, stop your ascent and follow on-screen instructions; Perform a safety stop if prompted, even if not planned. In severe cases, initiate an emergency decompression stop at 5 meters for 3-5 minutes. Always prioritize slow, controlled ascents and heed the computer’s warnings to prevent decompression sickness. Familiarize yourself with these procedures before diving to ensure quick, correct responses. The Leonardo’s alarms are designed to protect you, so never ignore them during a dive.
Maintenance and Troubleshooting
Regularly rinse the Leonardo with fresh water and dry it to prevent corrosion. Store in a protective case. For issues, check the user manual or update the software. If problems persist, contact Cressi support.
