Beskrivning och funktioner för Cressi Edy 2

Cressi Edy 2:

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 (available for Windows Vista).
