understanding dive computer

[pixieheart1]

I am new to diving and have the Cressi console leonardo computer. I can
not figure out where the computer will tell me how long a surface interval
I will need to have between 2 dives. Is it in the dive planning menu?
I have taken the online course and still didn't find the answer.

I have 0 knowledge of the computer itself. So I may be totally off base. But I feel that it may not explicitly tell you what your SI has done to your pressure group. It may adjust your ndl's on follow up dives automatically. I could be wrong though. On my Mares Puck, it tells me you have this long before you have completed your degassing right on the main screen.

Usually the plan mode tells you how long you have given how long you you are currently out. It pays to read the manual.

This website has a tutorial/dive simulator using the cressi leonardo for only $4.99. You might find it helpful to take it for a virtual dive or two.

..... I can not figure out where the computer will tell me how long a surface interval I will need to have between 2 dives......

The Cressi Leonardo (and many other dive computers) does NOT provide that information as its dive planner is limited to the NDL limit if you had to dive right now.

For planning series of multi-level dives - and related surface intervals - you might want to use a dive planner such as divePAL.

Your surface interval is up to you. It depends on how long and how deep you would like your next dive to be. You can use the plan mode on most computers to figure that.

I use my tank size and SAC rate to figure out how long I want to stay down at my plan depth on dive #2. The SI is then adjusted so that I won't violate NDL (with a small margin added for unplanned OH SHEEPs!) and when PLAN mode tells me I can splash in again, I go for it. I often use my dive tables to ensure the numbers make sense.

Thanks for pointing out that I should read the manual. I hadnt thought to do that....geez....I have read it about a 100 times and was merely looking for an answer.....Thanks for the great advice though...genius idea

The thing about factory manuals for many dive computers though is that they suck as far as readability goes for the average person.

If you are not an engineer or lawyer used to double speak, confusing the hell out of people terms, roundabout ways of using twenty words to say what could be said in four, or just plain enjoy seeing people in turmoil, they are an abject lesson in frustration.

I have seen them for Oceanic, Mares, Suunto, Uwatec, and all of them look like they were written by the same sadistic individual versed in mental torture.

The exception so far is the one for my shearwater predator. It looks like it was written by a diver and is clear and easy to understand. Coupled with Alberto's on line course it is a breeze to get used to and use. Others could take a lesson from them.

Then they'd be able to send their manual writers back to the KGB to resume their old jobs.

I have only owned one dive computer so far--a Suunto--and I was pleasantly surprised how well the manual was written. For a company not headquartered in an English-speaking country, I expected some awkwardly written sentences or over-reliance on diagrams instead of text. But it all made sense and flowed well, I thought. I suppose I may have had low expectations.
