RANGEMASTER CRF 900: SPECIFICATIONS
The LEICA RANGEMASTER CRF 900 can be
put to use in a variety of applications.
Hunters can determine the distance
of an animal in unfamiliar terrain, estimate
the odds of a hit, and adjust the rifle
accordingly. Sailors can determine the
distance to buoys and other landmarks,
while architects and landscape planners
It was during an ibex hunt in the Tien Shan Mountains of
Kyrgyzstan, where the LEICA RANGEMASTER CRF 900 really
came into its own. On one occasion a buck was standing high up
on a ledge, and my guide urged me to shoot, but I didn’t. The man
only calmed down once I showed him what the range meter had
to say: ‘493 yards’. On another occasion a guest hunter fired at
an ibex on a high mountain pass. The poor thing scuttled off
limping. This accident could have been prevented if only I’d had a
few seconds to measure the distance between us and the animal,
which we determined to be 453 yards. During the following
search mission – which was unfortunately fruitless – at an
altitude of 4757 yards, I made another astounding discovery:
there was a rock wall which I estimated to be 400 to 550 yards
away, but the distance turned out to be beyond the range
of the laser – that’s how far off the wall was. It seems that,
at extreme heights, the human eye is a lot less trustworthy
than one would think.
My mountain hunting expedition led to the following realization:
the optical system of the LEICA RANGEMASTER CRF 900 can be
used for most wildlife observations, especially in the daytime,
when it will deliver an immaculate view without having to deal
with twilight or darkness. The 7x enlargement and the large view
image generate a brilliant picture ideal for the majority of hunting

purposes, easily satisfying my needs in terms of magnification,
clarity and contrast. I frequently chose to work with the range
meter instead of the 10x42 binoculars – at least when I needed
to orient myself quickly – but that’s not to say that it’s a complete
replacement for a hunting scope.
I had a lot of fun working with the LEICA RANGEMASTER CRF 900.
I used it to revise distances I had previously estimated in my
home hunting grounds, and I believe it will turn out to be an
indispensable instrument in future hunting trips abroad.
Especially in remote places, where more often than not
communication is a problem, the guest hunter can quickly obtain
essential information provided by the laser device, refrain
from taking unreasonably long-range shots, show the evidence
why and ultimately avoid terrible accidents.
Last but not least, here’s a little tip: you’ll probably
carry the range meter, hanging around your neck, inside its
protective case. With the adrenaline of the moment, it can
happen too quickly that you pull the meter out to take a quick look
at the game and drop the protective case by accident – and
the last place you want that to happen is when you’re hunting
on horseback , as one does in Kazakhstan and Kyrgyzstan.
So don’t be like me: secure the case to your belt with
a second strap! PROF. DR. KURT FITZLER
can survey a landscape – at a range of
400 yards the LEICA RANGEMASTER
CRF 900 will measure with an error
tolerance of ±1 yard. Of course, the
range meter can be used for a lot more
than topography: you could just as
easily check the height of your kite and
discover whether it has become a hazard
to aircraft; clouds will also reflect the light
of the laser, and so you could determine
their height as well, provided that
they’re within the reach of the LEICA
RANGEMASTER CRF 900. All in all, it’s
an amazingly accurate, versatile, and
compact device built to the legendary
Leica standard.
Small, light, robust and waterproof: the
Rangemaster CRF 900 is the perfect hunting
companion, where maximal performance is
expected from a minimal amount of equipment
