Rbt And Tank Reserve; Rbt During A No-Decompression Dive - Seac GURU HP User Manual

RBT and TANK RESERVE

The RBT value (Remaining Bottom Time) is shown in the lower part of the GURU screen.
The RBT value is calculated based on the current breathing rate. The GURU may need from 2-5 minutes of diving in order to acquire
sufficient data to calculate the RBT. Until a reliable RBT value is available, the RBT value is not displayed ("---"). The RBT value differs
from person to person, even at the same depth and tank pressure.

RBT during a no-decompression dive

If the dive remains within the no-decompression limits, the RBT value indicates the anticipated time remaining - given the current
depth and breathing rate - before the tank reaches reserve pressure (TANK RES, which can be set from the TRANSMITTER menu).
E.g. (If TANK RES. = 30 in the TRANSMITTER menu)
In a no-decompression dive, the RBT value will be "0" when there is 30 BAR of pressure left in the tank.
The TANK RES. (reserve) value can be changed from GURU's TRANSMITTER menu. The minimum value of TANK RES. is 10 BAR
and the maximum is 50 BAR.
The RBT is a purely mathematic-statistical value based on the information acquired by the Transmitter. It cannot in any way
anticipate behaviors that increase gas consumption such as overbreathing or similar.
It must be used solely and exclusively as a generic statistical indication. It cannot in any way replace proper dive planning or an
awareness of your own physical and mental faculties.
Do not use the RBT value to extend the dive beyond the value established during planning. If you have any questions about how
to correctly program a dive, contact your instructor.
