Cressi Edy dive computer
By Johan Boshoff
If you are looking for a compact, watch-type computer that is suitable for both scuba and free- diving and is extremely compact in size, then the Cressi Edy dive computer is for you. Tere are a number of
computers on the market and it is hard to know which one to buy. When deciding on a computer, the first thing that I always look at is its size – I personally don’t like big computers for recreational diving. Te smaller and more compact they are, the more chance there is that I will buy it. Te second thing that I look at, is whether it has all the functions that I need for my diving. Finally I make sure that it is easy to use and to change the setings. I found all of this
in the Cressi Edy dive computer. It is small and very easy to use and I can wear it and keep it with me rather than leaving it in my bag. As I never have a log book, it conveniently logs 60 dives and I can easily download these to my computer for later references (graphs and analysis of the nitrogen saturation at any time for each of the 12 theoretical tissue compartments are monitored).
Technical features: • Audio and visual alarms. • Graphic indicator of nitrogen saturation.
• Graphic indicator for CNS oxygen toxicity.
• Graphic indicator of ascent speed. • Back-lit display. • Differentiated ascent speed depending on depth.
• Complete processor for dive data, also with any decompression, for dives performed with air or with nitrox mixes.
• Complete setting of FO2 84
and PO2 parameters with the possibility of seting PO2 between 1.0 bar and 1.6 bar and of the FO2 between 21% and 50%.
• Maximum depth alarm (can be inserted by the user).
• Changing of the measurement unit from the metric system (metres and °C) to the imperial system (ſt and °F).
• Instant PO2 indicator. • Safety stop indication (not compulsory) at the end of the dive (between 9,9m and 3m).
• Possibility of setting Gauge programme (depth gauge/timer).
• Possibility of setting Free programme. • Logbook (30 hours or last 60 dives) complete with dive profile (thre independent logbooks for the Computer, Gauge and Free modes). • Dive profile can be reviewed without interface
(intervals of 30 seconds in the
