Redundancy is always good practice in scuba diving. Genesis Scuba encourages the use of additional
depth & time instruments during dives to be able to closely monitor dive profiles and compare
instruments. In the unlikely event your dive computer fails, you’ll have additional backup
instruments to be able to monitor your dive profile and safely ascend to the surface. Consult with
your Genesis dealer for a complete list of redundant instruments you can acquire.
Turn on your Genesis Graviton computer before each dive. Make sure the battery is fully charged
and your settings for either air or nitrox are correct. Additional depth, time, deep stop and safety
stop settings/alarms are also available.
Flying after diving and driving to altitude, which are covered during your Open Water Diver training
or equivalent must also be observed. An airplane icon will be present on the Graviton screen after
each dive and it will remain on the watch’s screen until you are allowed to fly on an airplane or drive
to high altitudes. Please observe this precaution.
Your Genesis Graviton dive computer is intended only to be used either at sea level or at dive sites
where the altitude level does not exceed 3000m / 10,000 ft. OSL (Over Sea Level). Make sure you
check the altitude of all dive sites prior to diving when not at sea level. Incorrect altitude entries will
result on higher risk of decompression sickness due to the decreased atmospheric pressure found at
altitude.
Divers must never exchange dive computers during group diving activities. A dive computer that
was originally used by a particular diver is currently monitoring gas absorption and release the
tissues linked to that particular diver and based on the particular depth and time profiles. Even if
divers in a group were in close proximity that does not ensure the exact depth and time the other
divers performed was the same, let alone during multilevel diving or multiple dives scenarios during
the day. Each diver must provide the means to monitor his/her own depth, time and NDL for each
dive.
If the dive computer was forgotten at the surface and the diver performed a dive without his/her
dive computer, that dive computer should not be used again; only after both the diver and the
computer have spent a complete 24-hour cycle at the surface to ensure full tissue outgassing & the
computer is also free of all previous gas intake / release information. Using that ‘forgotten’ dive
computer again on a subsequent dive will carry a very high risk of decompression injuries as the
profile provided by the computer will be completely inaccurate and will not reflect the real gas
absorbing/releasing timers in the diver.

Nitrox
Be sure to personally check the oxygen concentration in each cylinder prior to use. If you are
certified to use oxygen enriched air at a concentration higher than 21% (AIR), use the Nitrox
computer settings to enter both the correct EANx mix from the cylinder you are going to use and
adjust the desired PO/ MOD in your Graviton dive computer nitrox settings. If you are
not
qualified
to use oxygen enriched mixes, use only cylinders that contain air.
The Graviton input value for EANx settings does not accept decimal fractions. If the O2 reading in
the tank label or oximeter is fractional, round up that value. For example, a 32.2% oxygen
