1. The SCUBA DIVING COMPUTER mode allows you to choose between the uses of air or a nitrox mix with up to 50%oxygen, with the partial pressure of oxygen gas between 14.5 psi to 23 psi (1.0 to 1.6 bars). Depending on your diving skill level, physical health and age, youcan program in a safety factor for either aggressive or conservative dives profiles. Three different safety levels can be set, a maximum depth alarm that can be inserted if and when required, graphic display of nitrogen saturation andcentral nervous system (CNS) oxygen toxicity, graphic indicator of ascent speed,thermometer and a wide range of audio and visual alarms. A high performance logbook memorizes 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 30seconds, this integrated Dive Profile function does not require any accessory interface. A handy History function memorizes 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 program the dive using decompression software and perform dives in accordance with dive tables. The functions indicated provide the current and maximum depth, the dive time (including seconds), ascent speed, a temperature, a traditional watch and ahandy 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 calculates the average depth of the dive and records the temperature at the maximum depth reached, it also has aProfile 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 intoconsideration, 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) along with temperature. This mode also has its own independent Logbook that is able to memorize 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 memorizes the total number of dives in the day, indicating the deepest dive and its duration. This daily memory can be reset at any time.
The 3 Volt CR2032 battery of the Edy II can be quickly replaced by any watchmaker. The battery has an approximate battery life of two years at 50 divesper year, An accessory interface is available to download all the data recorded and transfer it to a PC, thus allowing the user to access many more functions (not available for Windows Vista).
The Edy II uses the Buhlmann ZH-LB algorithm, redesigned by Randy Bohrer. It uses a 12 tissue model with tissue half-times from 5 to 640 minutes. The computer is calibrated for salt water, has a measuring range of 0' to 328' (0 to99.9 meters) in computer mode and 0' to 656' (0 to 199.9 meters) in gauge mode, and has a maximum surface time calculation of 48 hours. If altitude diving is a concern, the computer will properly adjust from 0' to 19,685'(0 to 6,000 meters). The computer can also be used in either imperial units (feet/degrees Fahrenheit) or metric units (meters/ degrees Celsius).

Comments about Cressi Cressi Edy II Wrist Computer:
I use this watch for freediving and spearfishing. It has all the basics and very easy to read display. It lacks some of the fancier features of other freedive computers, but for my purposes, it's served me very well.

Comments about Cressi Cressi Edy II Wrist Computer:
Excellent computer for people who freedive and scuba. Freediving mode displays bottom time in minutes and seconds.
Could be used for basic technical diving in dive mode or switch to gauge mode for more advanced tech diving.
I only have one minor complaint about the battery not lasting quite so long but I do use it a lot. It would also be nice if the battery was a little easier to replace.

Comments about Cressi Cressi Edy II Wrist Computer:
I am a warm water recreational diver. I have been diving for a lot of years and while I have a lot of dives under my belt, this is my first computer. Very easy to use and very easy to read. After 1 or 2 dives and reading the manual, you realize how simple it is to use. Plenty of features. Also, the small size is wonderful. I wore it all week on my dive trip last week including when I played tennis. Very comfortable. Highly recommended!

Comments about Cressi Cressi Edy II Wrist Computer:
Use it as a back up to my Smart Com (air integrated). Though I found myself checking the Edy2 for info and the Smart com for Air. Plus the Edy2 has the 3min safety stop count down and the Smart com didn't.
