LOW LIGHT ILLUMINATION

2. Strength lies in quality.
Visibly later than yesterday the moon rises from the dark sky. More or less just a thin crescent in the icecold
January night. Frozen and quiet — the borderless Taiga plains. After a long long wait a distant howling of
wolves. The guide nods his head. Using his hands as a funnel he imitates the keen predator. The response
comes swift and clear. Closer and closer the howling approaches our hide out.
I grasp my gun tighter to drive away the ice cold shiver.

German Philosopher
It’s the weakest hunting light and the iciest cold — technology without compromises is sure to pay off now.
Unsurpassed in light transmission, field-of-view and contrast. Unequalled in robustness and design the
HELIA CB is sovereign here in its strengths. The dimmable dot remains clear on even the darkest shadows,
remaining in sharp and fine contrast to the body of the game. Rifle ready, body tense — the HELIA CB
leads to the ultimate goal with certainty.

The uncompromised maximum in lowest light
conditions: Both fixed power models provide
unmatched light transmission ratios and the
industry’s widest field-of-view. The generous
exit pupil provides outstanding viewing comfort
— a decisive advantage in the very last
shootable light.
The KAHLES HELIA CB 8x56 model is also
available as LS- (rail) or S-version (Steel)
upon request.

5. The last hunting light — the moment of truth for professional hunting optics.
The test of true optics.
KAHLES, as the world’s oldest riflescope manufacturer, has always been the industry leader with state-of-the-art,
innovative, light-effective riflescopes. And for good reason, hunting success in Austria is dependant upon the
twilight performance of the riflescope.
KAHLES has led the pioneering efforts in riflescope development and design, especially in the advancements in
brightness and contrast. This is expressed in numerous pioneering milestones from KAHLES. Such as the world’s
first serial riflescope with multi-layer coatings — a HELIA with more than 90% light transmission, unprecedented
at the time (1972).
HELIA CB
THE SPECIALIST — RIGHT ON THE EDGE OF PHYSICS.
{
But this continous strive to push the laws of physics continues with all elements of KAHLES riflescopes.
From the typically large entry pupils to the proprietary AMV coatings, KAHLES continues its pioneering
efforts. In fact, KAHLES AMV coatings, which are, today, realizing a nearly lossfree transmission in the critical
dusk-time spectral range between 500 and 540 nanometers, provide the user with a crisp clear image at all
times. Unsurpassed wide field-of-view with excellent edge-to-edge clarity and outstanding image correction
are also a recognized KAHLES’ standards today.

6. The CB illumination is similarly recognized as the standard by which all other illumination is compared. The
reticle is especially dimmable and scatter-free, providing a clear and fine contrast against the body of the game.
The illuminated reticles on all HELIA CB scopes increase in size as magnification is increased hereby providing
a confident feel for the shooting distance. The noiseless, easy-to-operate, illumination turret is conveniently
located on the left side of the riflescope. Fascinatingly constructed out of the highest quality materials and
without any compromises, the HELIA CB is built to endure for generations.

7. Optimized KAHLES AMV coatings realize
nearly loss-free transmission in the
critical spectral range of light (about 520
nanometers). This allows to extract the
very smallest reserves of light during
the lowest light
shooting conditions.
Complex optical designs with up to four objective
lenses creates an unprecedented distortion-free image
with an extremely wide, edge-defined field-of-view.
Extremely durable housing machined by
state-of-the art production methods from a
single piece of high-grade material.
Extremely precise adjustment mechanism
creates absolute repeatability.
A spare battery is conveniently
located in the windage turret cap
(accessory upon request).

The state-of-the-art analog stageless
control for night lighting is completely
soundless and can dim the reticle to an
extreme minimum. The multiple LED-construction
realizes an even illumination
with an absolute minimum in straylight.
The battery lifetime is up to 110 hours.
