Diving computer

只吹潛水同海有關的話題

Diving computer

Received the DAN's magazine yesterday. There is a discussion on various dive computers logarithm employed. Several computers were studied with very interesting results. They all gave different deco time and the difference can be quite big. Please refer to the original text for details.

Cochrane"Commander" and Citizen"Cyber Aqualand" were also tested. Some interesting quotes: DAN America data indicate that in 2002, 72% of the divers who were treated for DCI had been using dive computers, similar to the 2000 figure of 73%. 1997 DAN America data indicate that a very high proportion(93.7%) of such cases reported diving 'within the limits' of their devices, similar to DAN SEAP.
The results from this experiment shown that the decompression advice displayed by different computers can and ofter does vary greatly, especially with repetitive dives. The advice is to choose a dive computer that is relatively CONSERVATIVE on the types of dive profile that you are planning to conduct.
Finally, just to steal a phase from the same edition of DAN: Just because a computer says that you can do something, does not necessarily mean that it is true!!!!! You have been warned. Happy diving.

會不會因為佢地個si 時個 half-time 由海軍表的 120 mins 轉成 優閒潛水的 60 mins 有關呢.

當年個table 係由海軍個表演變出來但係為了顧及優閒潛水的潛水模式而將si 時餘氮釋放半時減一半. :-k

I do not know but I suspect the answer is NO. Otherwise there should not be so many decompression theories still floating around nowadays if the US Navy 120mins half-time is absolutely correct.

那如果連保守的120min 都不是正確的, 那60min 豈不更...唔安全?
因為文章說是電腦得出不同結果 especially with repetitive dives才使我有這個聯想.

ot 一下, 依家diver 考慮買電腦錶, 好多時聽到考慮因素之一是 "冇咁保守", 冇咁易lock錶"...... :neutral:
