Features:
- Specially calibrated for use in the southern hemisphere.
- Sturdy construction provides years of service.
- Unique pivoting card design allow the AC40 to function even when held on
an angle.
- Rotating bezel.
Description:
Employs the special bearing system to indicate exact orientation even if
tilted.
With adoption of the unique bearing system , it is the world’s only diving
compass indicates the exact orientation even if tilted. In general, with the
normal oil-filled one -point support compass, it needs to keep the horizontal at
the time of use as the rotating disc comes into contact with the case and
stopped when it is tilted.
With adoption of the two -point support system and performing careful special
balancing of the rotating disc, the ac-40 indicates the correct orientation
without maintaining a horizontal of the compass , and it allows extremely easy
to use operation and accurate compass navigation.
The encapsulation of an optimized oil for compass
Inside , encapsulate the less volatile oils in viscosity to optimize the
rotational speed of the compass , thus , it has improved the accuracy of use and
navigation under pressure. In addition, the oil is carefully selected by
extensive verifications even for operation at low temperature, under which the
rotation tends to be dull due to the oil viscosity increases. So you can use it
safely even in ice diving.
Heat-resistant engineering plastic employed
The compass body made of heat resistant engineering plastic, the hear resisting
property is 1.5 time of conventional, which has significantly reduced failure
rates such as deformation under scorching sun. Also ,with the excellent gas
permeability it effectively prevents the generation of bubbles.
Tension automatic adjustment belt/standard accessories
The specially made list belt with a built-in spring adjustment mechanism in the
buckle is supplied as standard accessories. It will prevent the phenomenon in
which the fitting of the depth meter becomes loose as the result of diving suit
shrink at wrist due to the water depth increase.
Long-hour noctilucence adopted as standard
The scale plates of the compass is painted with Japanese-made special
phosphorescent agent, which will glow stably for hours once exposed to the
light. It is ideal for night diving.
