Cressi Leonardo has 1 control button for setting and retrieving data. Simple and intuitive interface makes this dive computer user friendly and acceptable for the very beginners. This Cressi dive computer has main and alternative displays for operations on surface and underwater.

To keep the diver well informed in oxygen toxicity level and Ascent speed, dive computer has bar graph to display CNS O2 toxicity level and set of arrows to show Ascent speed respectively.

 


 

 


 

 


 

This Cressi dive computer has main menu system that consists of 9 sections. Besides Pre Dive mode (which is main Leonardo's display) we have few more modes:

  1. Logbook - where I could observe my dive data;
  2. Dive Set - that's the place where I customized Cressi Leonardo;
  3. Time Set - date and time setting;
  4. Plan - dive planner;
  5. Gauge - enable computer working as a gauge;
  6. PClink - use this mode to interconnect with PC;
  7. History - this mode shows all available dive history;
  8. System - set the units and RESET the system

 

We may access each of them from Predive display by pressing button. To do adjustments of specific parameters and to get inside the menus, I had to press and hold the button.

It was very easy to customize Cressi Leonardo! I worked out how to do it barely reading the manual - interface was very intuitive!

Diving with Cressi Leonardo was nice'n'easy! This streamlined dive computer has main and only one alternative display, but it is enough to be confident in any dive situation.

 

Cressi Leonardo: Diving With Air & Nitrox

I set my Leonardo for Nitrox with FO2 - 32% before diving.

 

Cressi Leonardo NO-DECO Card

If you set Air dive mode - display looks similar, except indicators Nitrox and CNS.

Upon reaching certain depth during the diving profile, computer may give Safety and Deep stops prompts. These stops are not mandatory, but it is a good diving practice to follow them.

Cressi Leonardo is factory set for Safety Stop reminder and diver can't disable it. Also it is factory programmed for Deep Stop reminder (this one we may disable). I followed Safety Stop prompt and did this procedure at 3 meters for 3 minutes, as it said in books. And the most important values at this moment - Safety Stop depth and Time.

Cressi dive computer monitors constantly ascent speed. When I was ascending faster than should - Leonardo started beeping and 2 or 3 UP Arrows with message SLOW would be displayed. Alarm is loud enough to hear even with hood.

During diving with Nitrox computer calculates related to diving with Nitrox crucial parameters. Those parameters are:

  • High PO2 alarm goes on if current value exceeds the maximum value that you programmed when we go deeper than certain MOD;
  • Oxygen toxicity (%CNS) – upon reaching the allowable level of oxygen exposure, dive computer will give this alarm by beeping and displaying full bar graph

 

If we exceed NO-Decompression Limits (NDLs) - dive computer will activate Decompression mode to help us perform decompression procedure and resurface safely. Cressi always recommends to stay out of Decompression diving.

Cressi Leonardo has "Omitted Decompression stage" alarm. If in some reason diver misses Deco Stop completely and ascends - computer turns ERROR MODE and loks itself for the next 48 hours.

 

Cressi Leonardo: Diving In GAUGE Mode

Third dive mode of this dive computer is Gauge mode. In this mode diver may use technical mixes or go freediving. Leonardo will function as a bottom timer. It monitors only current depth, time and temperature and it doesn't perform any decompression calculations. So it is completely diver's responsibility to figure out all bottom times and depths.

During Gauge mode, Cressi Leonardo displays following values:

  1. Elapsed Dive Time (EDT);
  2. current depth;
  3. maximum depth during dive;
  4. temperature;
  5. Ascent speed indicator(in case of ascending);
  6. battery indicator;
  7. all other applicable icons

 

Back to Top

 


 

 


 

 


 

On depth less than 1 meter Cressi Leonardo switched on Surface mode and displayed me following parameters:

  1. Surface time;
  2. Desaturation time;
  3. No-Fly icon;
  4. Max depth and duration of the last dive;
  5. all other applicable notations, like Nitrox, or Deco

 

If I submerged again in less than 2 minutes - dive computer would consider it the same dive, if I submerged after 2 minutes passed - this dive would be considered as a new repetitive dive with all corresponding calculations.

On surface I could access folowing functions:

  1. Dive Planner;
  2. Logbook that stores 60 latest dives or 70 dive hours;
  3. Dive History;
  4. Dive Profile (need to have special software installed on your PC and PC download kit);
  5. PC function - download to PC your dive profiles by using optional kit;
  6. System RESET - reset all calculations for repetitive diving and return all settings to factory default

Great Dive Computer But Challenged by a Sticky Compass

Overall I like the Leonardo offering. It is clear, right-sized and has a great feature set. I have not been able to rely on the compass in a console as it frequently sticks. This has the negative of misleading you into believing you are traveling in the right direction. I have not determined whether it is affected by the depth, however it is certainly affected greatly by position. If I can correct this problem I will be thrilled with the package.

Great Cressi Leonardo - Great Display & Easy To Use

I've been diving with Cressi Leonardo for more than 1 year already. I can't be more happy with its performance than I am!

I love its large display with easy to read digits and all vital dive data shown on one screen. Also high level of customization - it's another big PLUS for this dive computer.

I use Cressi Leonardo with compass and pressure gauge - this console will last with me forever!

Great Dive Computer For The Price

Cressi Leonardo - great computer for the functions-specs-price combo!

It is easy to learn and use, because of its one button easy access user interface.This dive computer does everything you need to enjoy recreational tropical diving, without having high-tech device!

I have bought one last year for myself and later got one for my wife and she learned it quickly, thanks to easy to follow documentation and intuitive user interface.

I definitely recommend Cressi Leonardo to any of the recreational diver, who want to have easy-going dive computer with very reasonable price!

Cressi Leonardo - Perfect Dive Computer For The Recreational Diver

As this dive comp is my first of this kind - I may say that I am very pleased with its performance. I had 28 dives with it and it did the job perfectly so far.

User documentation needs some work though, but even for the beginner it wasn't too hard to figure out and learn functions Cressi Leonardo. It has very customizable set of functions, like FO2, PO2, Safety Factor, Deep Stop and Altitude program.

I like two levels of Safety factor adjustments, as this gives me extra-safety during my diving experience. Cressi Leonardo has intuitive and easy to understand display and it is easy to read at any light conditions, thanks to its large display, strong backlight, and sharp digits.
