The Edy II combines complete programmes for three different types of dives in one single instrument: 1- scuba diving (air or Nitrox) 2- technical diving (depth gauge and timer to a depth of 200 metres) 3- free diving. Edy II is also an attractive, compact digital wristwatch. It has dual time zones, an alarm function and the display is back lit so that figures can be read even in poor lighting conditions.
1 – The SCUBA DIVING COMPUTER mode allows you to choose between the use of air or a Nitrox mix with up to 50% oxygen, with partial pressure of this gas of between 1.0 and 1.6 bar that can be chosen by the user. Three different safety levels can be set (Safety Factor), a maximum depth alarm that can be inserted if and when required, graphic display of nitrogen saturation and CNS oxygen toxicity, graphic indicator of ascent speed, thermometer and a wide range of audio and visual alarms. A particularly high performance logbook memorises a large amount of data from the last 30 hours of dives or of the last 60 dives, which can be scrolled through, one by one, at intervals of 30 seconds, thanks to the integrated Profile function which does not require any accessory interface. A handy History function memorises maximum depth, hours spent in the water and total number of dives performed.
2 – In GAUGE mode Edy II is a valuable instrument for those who wish to programme the dive using decompression software and perform dives in accordance with tables, as required in technical dives. The functions indicated provide the instant and maximum depth, the dive time (including seconds!), indication of ascent speed, a thermometer, a traditional watch and a handy chronometer (hours, minutes and seconds) to accurately calculate ascent and decompression stops. A depth alarm can also be enabled if and when required. The GAUGE mode also has its own logbook which even calculates the average depth of the dive and records the temperature at the maximum depth reached, it also has a Profile function to review the dive at intervals of 30 seconds and an independent History function to record only those dives performed in GAUGE mode.
3- In FREE DIVE (FREE) mode all the needs of the free diver have been taken into consideration. Therefore indications of current and maximum depth are provided as well as dive time (minutes and seconds), ascent speed and a depth and/or time alarm can be enabled. On the surface the interval between one dive and the next is indicated (minutes and seconds) and there is also a thermometer. This mode also has its own independent Logbook that is able to memorise up to 60 dives, filled with data, each of which can be reviewed with the integrated Profile function at intervals of just one second. The History section memorises the total number of dives on the day, indicating the deepest dive and its duration. This daily memory can be reset at any time. The battery of the Edy II can be quickly replaced by any watchmaker. An accessory interface is available to download all the data recorded and transfer them to a PC, thus allowing the user to access many more functions.
Your "C-Card" proves you're a diver, but your log book proves your experience and frequency of diving. Be prepared to prove your experience when on vacation with your electronic log book. This software is an application for managing logged data on your Cressi Edy II Dive computer. Software gives full color line and bar graphs of dive profile and tissue loading. You will be able to review the profiles of your last 60 dives in all three modes of the computer. The Dive, Free or Gauge mode can be reviewed. You can see graphs and analyze the nitrogen saturation at any time for each of the 12 theoretical tissue compartments monitored.
The second version of the Archimede computer, with its renewed look, has new sophisticated software that is able to manage two different Nitrox mixes during a dive, thus allowing you to choose at any time during the same dive. The features of Archimede, which were already outstanding, have been considerably improved for scuba divers and free divers as well as technical divers, who will find the new GAUGE function an indispensable instrument for precise monitoring of all their dives.
Archimede 2 is, first of all, an intuitive computer that is easy to use, both for the beginner and the professional. Although it has many functions you are not obliged to use them. Once the computer has been set for the use of air it does not require any further adjustment for subsequent dives as the computer activates automatically upon contact with the water and is perfectly able to calculate any dive, with or without decompression, in total automatism. However, even the most demanding divers have been taken into consideration, those who use Nitrox mixes and want to de-saturate in greater safety, by using Nitrox mixes whilst ascending, or who want to use the instrument during free diving or technical dives. The new software analyzes the data of 12 sample tissues (previously 9) for even more accurate monitoring of tissue saturation and de-saturation mechanisms.
The possibility of being able to use a second Nitrox mix during the same dive has now been introduced to faithfully monitor and assist those divers that prefer de-saturation with Nitrox mixes, a practice that offers greater safety to the dive and that is used by an increasingly large number of enthusiasts. The first mix can contain a percentage of oxygen ranging from 21% (air) to 50%, the second between 21% and 99% (pure oxygen). The fraction of oxygen of both mixes is set on the surface, whilst the use of the two different mixes can be chosen at any time during the dive. Naturally, the partial pressure of both of the mixes can also be selected in a wide range of between 1.0 and 1.6 bar. Other new functions include the maximum depth indicator, which is now visible during decompression; the choice of three different Safety Factor levels; the ascent speed indicator (expanded); the temperature sensor (faster) and the display back-lighting (clearer). Lastly, the all new GAUGE function, used both for free diving and technical dives, which selects just some of the instrument’s functions, such as instant and maximum depth, duration of the dive (in minutes and seconds), time and ascent speed. The operating range of the GAUGE function reaches depths of up to 200 metres.
This is the 3-instrument version of the Archimede 2 Console.
A compass is situated on the back of the console, at the computer. Front-hinged and angled so as to allow free access to the back of the Archimede computer.
It is possible to replace the computer battery and reset the residual nitrogen memory without having to disassemble the compass, making these operations quick and easy.
The compass can be angled in 4 different positions of the instrument so it is easy to read in any situation.
The Cressi wrist compass allows easy reading in all diving conditions. The compass card moves easily even when the compass is not held level. The compass face is divided in 10° intervals, and is luminescent for ease of reading in low light conditions and night diving. The Cressi Compass can be read from above the face, or for gun sight accuracy, through the side window which give’s precise readings. Compass face is equipped with a lubber line to center with the body to increase accuracy when navigating, and has a rotating ratchet bezel with double pointed heading marker to mark your heading and keep you on course. Compass comes with wide wrist band designed to keep compass stable on your arm.
Mini 2 Gauge Console (Metric/Imperial)Mini-console 2 is a small compact console that houses the Cressi mini pressure gauge and a new, small, analog depth gauge. Both gauges are high quality instruments with a chrome plated brass case and the depth gauge has a diaphragm membrane function. Both gauges have a large circular easy to read scale.
On the luminescent face of the 70m/230ft depth gauge the first 12m/40ft depth readings are in 3m/10ft increments, (which correspond to the area of decompression stops), andÂ are widely spaced forÂ ease of reading. The face is divided into three different colored zones: green up to 20m/66ft, light blue from 20m/66ft to 40m/130ft, red from 40m/130ft to the end of the scale. The instrument has a maximum depth indicator that stops on the maximum depth reached during the dive.
The Mini-Manometer pressure gauge luminescent dial reads from 0-to 350 bar/5000 psi. The instruments face like the depth gauge is divided into three different colored zones: the area from 35 bar/600 psi and below is highlighted in red with a solid bar and red stripes. If gauge is used on deeper dives, the red scale extends and fades to 70 bar/1,300 psi. This provides for added reserve air indication required at greater depths. From 35 bar/600 to approximately 200 bar/3,000 psi is green and from 200 bar/3,000 psi to end of scale is blue.
The front glass lens is made to act as a pressure relief valve. In the event of a sudden increase in pressure inside the instrument, the glass rises slightly, allowing the excess pressure to escape. The instrument is housed in a small, modern shaped console boot, made from polycarbonate and desmopan, (a thermoplastic polyurethane) two materials that guarantee protection from shocks, scratches and which, at the same time, is very light.
The pressure and depth gauges are positioned in such a way that both instruments can be read quickly and easily in any conditions. At the end of the console, slightly to the sides, there are two loops for fastening the instrument to the BCD or harness so that it does not hang down with the risk of catching and damaging the environment.
Mini Console III is the three-instrument version of the Mini Console 2.
A compass is added on the back of the console to correspond with the depth gauge.
Here the position is also perfect for easy reading of the instrument.
At the end of the console, slightly to the sides, there are two loops for fastening the instrument to the jacket so that it does not hang down with the risk of catching and damaging the environment.
The Cressi mini pressure gauge is a small, light-weight gauge that has been specifically designed to avoid excessive strain on the HP hose that connects to the first stage of the regulator. The instrument has a metal case in chromium plated brass and is therefore extremely strong.
The front glass is made so that it also acts as a pressure relief valve. In the event of a sudden increase in pressure inside the instrument, the glass rises slightly, allowing the excess pressure to escape. The luminescent dial is calibrated up to 350 bar in the metric version and 5000 psi in the imperial one.
The area below 50 bar is highlighted in red, the one between 50 and 200 is green and that from 200 to the end of the scale is light blue. The instrument is housed in a small, modern shaped console, made from polycarbonate and desmopan, two materials that guarantee protection from shocks and scratches and which, at the same time, are very light.In the upper part of the protective shell there is a loop for fastening the instrument to the jacket so that it does not hang down with the risk of catching and damaging the environment.
