The first Cressi-sub computer integrated into a wristwatch. Weight and size are very compact making the instrument suitable for everyday use, and not only specifically for diving.
Despite its compact size, Edy combines complete programmes for three different dive types in a single instrument:
- scuba diving (air or nitrox)
- technical diving (bottom gauge and timer down to 200 metres)
- free diving
It is also a digital wristwatch, great looking, complete with dual time zone and alarm, and can be backlit to read data when there is poor illumination.
Technical details
Despite its compact size, Edy combines complete programmes for three different dive types in a single instrument:
- scuba diving (air or nitrox)
- technical diving (bottom gauge and timer down to 200 metres)
- free diving
For all practical purposes, these are three different, very sophisticated and complete instruments, which can be used by an incredibly wide variety of users.
Most of the software is derived from the recent Cressi Archimede 2 computer software and is a sophisticated Bühlmann ZH-L12 modified and developed by Randy Bohrer, with some 12 sample tissue compartments of and with saturation half-times of between 5 and 640 minutes.
Let's have a closer look at the three different instruments.
In the SCUBA DIVING UNDERWATER COMPUTER mode it is possible to choose to use air or enriched air mixes with up to 50% oxygen, where the diver can select partial pressure of this gas from between 1.0 and 1.6 bars. It has some three Safety Factors, a maximum depth alarm that can be inserted as you like, graphic display of nitrogen saturation and CNS oxygen toxicity, bar graph showing ascent speed, thermometer and a wide range of audio and visual alarms. A particularly high performance logbook memorises a great deal of data of the last 30 hours' dive time or the last 60 dives, which can be reviewed one by one at intervals of 30 seconds, thanks to the incorporated Profile mode that does not need accessory interface. A handy History mode memorises maximum depth, hours spent underwater and total number of dives made.
In the GAUGE mode, Edy is a valuable instrument if you want to programme the dive with decompression software and make the dive with tables, as required by technical dives. The functions indicated provide immediate and maximum depth, dive time (including seconds!), indication of ascent speed, thermometer, the classic watch and a really handy chronometer (hours, minutes and seconds) so you can precisely calculate ascent and decompression stops. It is also possible to activate a depth alarm. The GAUGE mode also comes with its own logbook that even calculates the average dive depth and records the temperature at the maximum depth reached, as well as a Profile mode to review the dive at intervals of 30 seconds and an independent History mode to record only the dives made in GAUGE mode.
In the freediving (FREE) mode, all the needs of free divers were taken into consideration. So indications of present and maximum depth, dive time (minutes and seconds), ascent speed are all provided, and it is possible to insert a depth and/or time alarm. On the surface, the interval between one dive and the next is indicated (in minutes and seconds), and there is even a thermometer. This mode also has its own Logbook that can memorise up to 60 dives, full of data, all of which can be reviewed with the incorporated Profile mode at intervals of just one second (world exclusive!). The History section memorises the total number of dives in a day, indicating the deepest dive and how long it lasted. This daily memory can be reset at any time.
To complete these three super dive instruments there is a handy digital watch, complete with dual time zone and alarm, and the display can be instantly lit (above and underwater) with a simple push of a button.
And any watchmaker can replace the battery in a flash.
An interface is available as accessory to download all the recorded data and transfer it onto a PC, so it is possible to access many other functions.
