to Dive Manager. The bookmark logs the depth, time and wa-
ter temperature as well as compass heading and tank pressu-
re when available. To make a bookmark in the profi le memory
during a dive press the SELECT button. A brief confi rmation
will be given (Fig. 6.3.).
6.1.3. TANK PRESSURE DATA
When using the optional wireless pressure transmitter the
pressure of your scuba cylinder in bars [psi] will be shown di-
gitally in the lower left corner of the alternative display (Fig.
6.4). Anytime you enter into a dive, the remaining air time
calculation begins. After 30 - 60 seconds (sometimes more,
depending on your air consumption), the fi rst estimation of re-
maining air time will be shown in the left center window of the
display. The calculation is always based on the actual pressu-
re drop in your cylinder and will automatically adapt to your
cylinder size and current air consumption.
The change in your air consumption will be based on cons-
tant one second interval pressure measurements over 30 - 60
second periods. An increase in air consumption will infl uence
the remaining air time rapidly, while a drop in air consumpti-
on will increase the air time slowly. Thus a too optimistic air ti-
me estimation, caused by a temporary drop in air consumpti-
on, is avoided.
