The Cressi Leonardo Dive Computer is designed and built by Cressi as an easy to use and easy to read dive computer. Compatible with both air and nitrox mixes it also comes in a range of colours.

 

Cressi RGBM Algorithm developed by Bruce Wienke, has been specially adapted by Cressi to offer safe decompression diving in a multi day, repetitive dive format which makes the Leonardo particularly effectively for holiday/liveaboard diving scenarios. The algorithm accommodates nine tissue compartments with saturation half-lives between 2.5 and 480 minutes.

 

Single Button Interface ensures simple menu navigation whilst the large clear display makes it very easy to read. Audible alarms alert the user to important information and the backlight makes the details clearly even in low light conditions.

 

User Changeable Batteries help to keep maintenance costs down and prevent periods of down time whilst the battery is replaced at a service centre.

Features

  • Algorithm: CRESSI RGBM algorithm.
  • Sample tissues: 9 with saturation hemi-phases between 2.5 and 480 minutes
  • Dimensions and weight: Diameter: 67 mm - Height: 27 mm - Weight: 135 g
  • Dive time: 0 to 255 minutes
  • Data acquisition frequency: 20 sec.
  • THERMOMETER: Resolution: 1 °F Measuring field: 23 °F + 104 °F Precision: +/- 35.6 °F/10min change °T
  • WATCH: Precision: +/- 50 seconds month average
  • 24 hours display
  • BATTERY:CR 2430 - 3V battery. 2 years average life (by 50 yearly dives).

Cressi Leonardo Dive Computer - Features

FeatureProduct Specification
Air Integration
?A dive computer with air integration allows the diver to view the current cylinder pressure on the dive computer display. Some models also display breathing rates. Air integration can be achieved through either a high pressure hose attachment or by using a wireless transmitter.
No
Apnea Mode
? A collection of features developed for free-divers and snorkellers that records how deep you are, how deep you have been and how long you can hold your breath.

Some computers include a faster sampling rate, specialized alarms
and warnings and specific logbook for apnea.
No
Computer Style
?The format denotes the style of the computer, whether it is a standard wrist sized unit with large easy to read display, a smaller watch sized unit which can be worn for every occasion but still packs in all the same features or a console mounted unit which are available with or without air hose integration.
Wrist
Display Illumination Type
?Dive computer displays typically have one of two illumination types. Phosphorescent displays glow when charged by light such as torchlight, it will continue to glow until its charge is depleted or it is recharged. Dive computers with a backlight facility use an internal light source to illuminate the display for a short period of time before turning off to save the battery.
Backlight
Display Type
?The type of screen affects what and how information can be displayed on a dive computer screen.

The simplest is a segment display that builds up characters using pieces of a fixed screen like a digital wrist watch. This is cost effective but limits the use of complex details.

A partial dot matrix screen stills uses a section of segment display for numbers but also has a section of tightly group squares that allow for text or graphs to be shown on the screen.

A full dot matrix screen completely does away with the segment section of the screen to give full use of the display.

Colour LCD screens use the same technology found in TVs to provide a high resolution colour display that gives very clear, vibrant dive information. The technology is more expensive but raises the computer to a new level.

OLED screens use a display of tiny LEDs that are very efficient and super sharp. The screen doesn't require a power hungry backlight and can still be seen in very low visibility.
Segment
Gas Switching
?Gas switching allows divers to use more than one gas mix whilst diving. For example, it allows a diver to switch from main breathing gas to an enriched oxygen mix to decompress faster when ascending.
No
Integrated Compass
?An integrated compass helps to reduce additional pieces of equipment that need to be carried. Some console computers are equipped with a standard magnetic compass. A number of computers now feature an electronic compass that is built into the unit itself and operated through the menu system. The electronic compass shows the magnetic North all over the planet by recalibrating the compass for your current localation.
No
Nitrox Compatible
?A Nitrox or EAN (Enriched Air Nitrox) compatible dive computer allows divers to benefit from the advantages of diving with an enriched oxygen gas mix including extended dive time without incurring mandatory decompression stops during the ascent.
Yes
PC Interface Compatible
?A PC Interface alllows divers to download previous dive information and profiles for viewing and analysis on a PC. Depending on the model of dive computer this can include depths, times, alerts, breathing rates, temperatures, etc.
Cable (not included)
Rebreather Mode
?A dedicated Closed-Circuit-Rebreather Mode that, depending on the computer, you can adjust and plan high and low setpoints, open circuit bailoutsand other features for diving with a rebreather.
No
Trimix Compatible
?A trimix compatible dive computer allows a suitably qualified diver to take advantage of the benefits of a Trimix gas consisting of oxygen, helium and nitrogen. Advantages include extended range diving and reduced narcosis effects.
No
User Changeable Battery
?Modern dive computers allow divers to safely change the battery themselves with minimal risk of damage through flooding due to incorrect installation. The logbook and memory of previous dives are typically saved during the battery change. Watch sized dive computers typically still have to be returned to an authorised dealer to have their batteries change as special tools and usually needed to open the body.
