6.1.2. Bookmark
It is possible to record bookmarks in the profile memory during a dive. These bookmarks are displayed when scrolling the profile memory on the display. The bookmarks will also be shown as annotations in the downloadable Suunto Dive Manager PC software.
The bookmark logs the depth, time, and water temperature, as well as compass heading (if the compass has been enabled).
To make a bookmark in the profile memory during a dive, press the SELECT button. A brief confirmation will be given.

6.1.3. Tank pressure data
The pressure of your scuba cylinder in bars (or psi) is shown digitally in the lower left corner of the alternative display. Whenever you start a dive, the remaining air time calculation begins. After 30 - 60 seconds (sometimes more, depending on your air consumption), the first estimation of remaining air time will be shown in the left center window of the display. The calculation is always based on the actual pressure 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 constant one second interval pressure measurements over 30 - 60 second periods. An increase in air consumption will influence the remaining air time rapidly, while a drop in air consumption will increase the air time slowly. In this way, an over optimistic air time estimation, caused by a temporary drop in air consumption, is avoided.
The remaining air time calculation includes a 35 bar/500 psi safety reserve. This means that when the instrument shows the air time to be zero, there is still about 35 bar/500 psi of pressure left in your cylinder, depending on your air consumption rate. With a high consumption rate, the limit will be closer to 50 bar/725 psi and with a low rate closer to 35 bar/500 psi.
NOTE
NOTE
Filling your BC affects the air time calculation due to the temporary increase in air consumption.
A change of temperature will affect the cylinder pressure and consequently the air time calculation.
