Ray-

Is it possible to disable all the computer features and use it as just a =
bottom timer? This is what I've done with my Nitek3 and I am quite happy =
with it now.

You plan your dive and you dive your plan. The tables are your plan. You =
plan your dive by creating your tables. You learn your dive by planning =
and creating your tables. There are only 2 things you need to do, keep an =
eye on your bottom timer and then use your tables when you ascend. You do =
enough of this and pretty soon the tables are a backup to your computer. =
The one between your ears.

These trimix computers are suckerbait. What do you sell a techdiver who =
has everything? Perfect for this application only, squeezing an extra $1900=
 out of dopes who are looking for a shortcut to hard work and experience.
