RBT and TANK RESERVE:
The RBT (Remaining Bottom Time
) is shown in the bottom-center part of the screen of your iDive/iX3M
The RBT is calculated according to your current breath rate. It may take up to 2-5 minutes in order to let the iDive/iX3M collects
enought data to calculate your breath rate. The RBT is hidden (“---”) if not enought data have been collected from the iDive/iX3M.
The RBT value is personal and can be different from person to person (even at same depth and same tank pressure)
RBT in no-deco dives
If no mandatory deco stops are required for your dive (safety stop and deep stop are not considered mandatory deco
stops) the RBT value is the time (in minutes) that you can stay at the current depth with your current breath rate before
your tank pressure reaches the TANK RES (tank reserve) set in the TRANSMITTER menu.
E.g. (If TANK RES. = 30 in TRANSMITTER menu)
If no mandatory deco stop are required, your RBT will be “0” when there will be 30 BAR of pressure left in your tank.
You can set the TANK RES value (from 10 Bar to 50 Bar) from the TRANSMITTER menu in your iDive/iX3M
WARNING:
The RBT is a pure statistic value!
The iDive/iX3M can not predict behaviours that can alterate your breath
rate like anxiety, stress or similar.
It can be used just as a mere statistic information. The RBT can never replace a correct scheduling of the dive and
the knowledge of your phisical or mental status.
NEVER use the RBT to extend your dive over the scheduled time.
If you do not know how to schedule a dive, ask your diving instructor!
