TUSA IQ700 Dive Computer?

Hi All

I have an IQ 700 Dive Computer and it has the worst manual I have ever
seen! I have emailed TUSA to ask them if they have an updated manual
(the one on the web site is the same as the awful boxed one). The
manual contains numerous inaccuracies and omissions!

Does anyone else have one of these dive computers who can explain the
different modes to me?

Cheers,

Kulgan.

P.S. The manual can be found here
http://www.tusa.com/PDFs/IQ700_manual.pdf

Specifically:

1. I don't understand what the Gage mode is for - why would you use
this rather than Dive Mode?
2. Why is there a Log mode and a Profile mode? What is the
difference?

Can anyone help???

Thanks,

Kulgan.

When you want a bottom timer and a depth guage, and only a bottom timer
and a depth guage. When you are diving deco profiles, with some other
gas on your person, Dive Mode doesn't do you any good at all.

Divers doing deep or long dives requiring decompression will use a
decompression strategy that is far different from the one that the
computer has. They will carry one or two extra gases to facilitate the
decompression, and the computer in "dive mode" can't handle that. They
will also use a bottom gas containing some helium, which has different
absorption/elimination rates.

The computer is not calculating your actual nitrogen absorption. It is
running a mathematical model that approximates data obtained through
observations, massaged for general using input from insurance companies.
We know these models are not real.

Hi

Many thanks for everyone who replied to help me out on this. I am now a
lot clearer!

I'm still not sure about the difference between Dive Log and Dive
Profile mode, so if anyone has any insight on this, that would be
great!

Thanks again,

Kulgan.

Correct, but since he was asking about computers, I figured that he
was just a beginning diver anyway and tailored my response to that...
I didn't want to confuse him too much by bringing up tissue absorption
rate models vs actual micro bubble formation... <grtin>

Download? Printable output? My Suunto gives me all that right on the face
of the "watch". And it tells time real good too.

Cool. If you could just get it to calculate MODs correctly and give you a
more reasonable ND time, it would be an excellent computer.

Rumor has it, the gauge mode is great.

Fully agreed, Greg!

u2 a D9 or you a D6?

Have you had the software updated in your D9
