DANGER
●
Never scuba dive alone. Always dive under the buddy system. Diving alone could lead to serious injury and
death.
●
Due to the speed of the scooter depth & pressure change may happen faster than usual.
The diver must be aware at all times with regards the status of the diver's depth and direction and carefully
monitor the diver's ascent rate as rapid surfacing and collisions could cause serious injury or death.
Please practice driving at low speed until you become accustomed to the handling of the scooter.
●
There are screen on the propeller cover for preventing from entangling wire and seaweeds.
However, do not dive with the scooter at the seaweed area.
●
Equalization ears.
Ears are equalized in the same way as for regular diving. However, the speed will cause water pressure
changes faster. Therefore, ears must be equalized faster and more frequently than usual.
As the diver's face is often turned upward when in a riding position, it is best to draw the chin back when
equalizing the ears in order make the auditory canal open up more easily.
●
Buoyancy adjustment.
Because the diver's hands are freed up during hands-free riding, the diver is able to operate the inflator and
exhaust valve as the diver normally would. Because the body is horizontal when riding the scooter, its position
can be kept stable by discharging air using the exhaust valves located at the shoulders or hips.
●
Using fins as a stabilizer.
During hands-free riding, fins are used as stabilizers.
The diver should try to keep the fins positioned near the center of the propeller cover during regular or high-
speed runs, keeping fins even with the propeller shaft of the scooter. The water current created by the
propeller will hit the fins. This will help counter the force that pushes the scooter to rotate in a counterclockwise
direction (rotation torque). When running at a slow speed, the upper body will lift slightly, causing the knees
to lightly bend. In this case, the diver must try to keep the fins horizontal to the propulsion direction, so that,
here too, they can act as a stabilizer.
The apollo underwater scooters are a multipurpose underwater scooter equipped with an innovative
"accelerator-based gear-less drive mechanism".
(except av-2CLASSIC)
●
Shifting gears while running.
On former underwater scooters, the gears could only be shifted by manually changing the pitch of the
propeller while the scooter was in a stationary position.
Having to stop each time to change the speed was difficult and inconvenient.
●
To overcome this problem, the apollo underwater scooter is now equipped with a mechanism that changes the
revolution speed of the motor. Now the gears can be shifted while running, eliminating the need to stop each
time.
The mechanism that changes the motor's revolution speed has made "gear-less" speed change possible.
Speed is no longer changed in phases by manual adjustment of the propellers pitch.
●
Propeller pitch conversion mechanism.
The apollo underwater scooter is also equipped with a propeller pitch conversion mechanism.
Please refer to the pitch selection on page 17.
NOTE
In this book, it utilizes only the av-2EVOLUTION diagram as an example.
Basic operation for another apollo underwater scooters are same as the av-2EVOLUTION.
