Binoculars for the Hunter
By Michael H Schulst. Man Magnum
Magazine, September 2005.
I have always advocated that, when
purchasing binoculars, you should select a
well-known brand and buy the best model you can
afford- Binoculars can last a lifetime if well cared
fur, so it makes sense to follow this advice.
However, binoculars are designed for specific
purposes, and just as a 375H&H isn’t the ideal
calibre For shooting classics, so too is a ‘mini’
binocular not ideal for hunting in low light or for
stargazing.
Special-purpose binoculars have their
place, hunting conditions in southern Africa vary so
widely that a compromise is called for. I’d say that
80% of our game is taken in bushveld or semi-bushveld
conditions — which require relatively low-power
binos. If most of your hunting is done in the Karoo
or Namibia, then more powerful binoculars may be
required- Most local hunting is done in sunny or
bright conditions, obviating the need for large
diameter objective (Front) lenses.
A friend who operates in Zimbabwe
uses what is possibly as close to the deal as you
can get, namely a Leica 8x32 (though the latest
Swarovski 8x32 EL might be even better). Last year,
he accidentally knocked the Leica off a ledge and
down an almost vertical embankment- Luckily the only
real damage was a sheared-off eyecup, but he nearly
had a heart attack. As a PH, his binoculars see a
lot of use and, while he can afford top quality, he
admitted to feeling remorse about the punishment
they unavoidably take when leopard-crawling, etc.
He asked me to investigate less expensive equipment
that could endure harsh treatment but wouldn’t break
his heart (or the bank) if broken or lost.
So we drew up a ‘priority list” of
the features he required — your personal list may
differ according to your needs. First came cost,
the target price was around R250O. Then followed
good or better-than-average optics, robustness
(including water resistance), compactness, light
weight, wide field of view with good panning
ability, and retractable eyecups for a full field of
view with glasses. Lastly, they must be comfortable
to use.
We settled on 8x magnification as the
most appropriate for his hunting conditions. The
more you use binoculars, the more convinced you
become that high magnification is one of the least
important criteria. First-time buyers, however, are
often seduced into thinking that the higher the
magnification, the better the value for money.
Unless required for a specific long-range purpose,
the reverse is generally true I remember glassing
the countryside from the top of a mountain on a
clear day in the Matatiele area many years ago and
being able to positively identify some cattle
grazing far in the distance. When I measured the
distance from the base of the mountain to the cattle
by car, I was astonished to find it was just on 7kms
— or about 5km ‘as the crow flies’. When you
consider that I was using a very average but good
quality Pentax 7x21 mini binocular you will
understand my point of view.
In binoculars of similar quality and
objective lens diameters, lower magnification
invariably affords brighter and more colourful
images with a wider field of view than higher
magnification. An oddity that I’ve periodically
experienced while comparing binoculars of different
magnification is that within a few minutes of
glassing, particularly in unfamiliar terrain, you
are hard pressed to discern whether they are 8, 9 or
10x. However, after a hard climb (or during a bout
of buck fever), the unsteady image through a bino
makes it very obvious that you are using high-power
glasses. Hence our decision to settle for eight
power.
Over the years I have owned several
makes of mini binoculars and have acquired a certain
fondness for them. As with handguns, it is far
better to have a mini at hand than a magnum in the
safe, so I rounded up a few of the many minis on the
market and frankly was very disappointed.
Naturally, you can get exquisite products if you
are prepared to pay upwards of R4000, but that
defeats the object of this exercise. Minolta, Canon
and Nikon products are all good, but price-wise they
did not fit our budget. So I contacted Lynx and was
informed that they had prototypes of their latest
minis which they would gladly submit for testing.
However, when the Lynx representative
dropped off the package it contained their existing
8x21s, a prototype 8x24, a prototype 10x28 and a
fourth, medium-sized bino marked 7x28 — a size and
magnification I had not requested so I set it aside
for the next week or so. The new Lynx minis are
rather appealing and sport push-pill eyecups, fully
internal focusing, and click-adjustable diopter
adjustment. Unfortunately I found their
butter-smooth central focusing knob too highly
geared and too light for hunting conditions, being
too easily bumped out of focus. The field of view on
the 8x24s was only barely acceptable, and that of
the 10x28s was too narrow. At under R2000, they are
interesting little pocket binoculars but are more
suitable for the amateur ornithologist or game
viewer rather than an active hunter.
While a 7x bino did not quite meet
our specs, and I was put off by the size of its belt
pouch, it dawned on me that Lynx had probably
included the 7x28s knowing that these were more
likely to match out particular requirements. Well,
gentlemen, l am over the moon. I consider these to
be one of the most suitable binoculars for our
Southern African hunting conditions. After removing
them from their carry case I was amazed to find that
they are almost as small and light as the Lynx 10x28
mini. The strong and well-designed nylon (camo)
carry case is large enough to accept the little
hinos without having to fold them down. This makes
them ‘quick on the draw’ — a definite plus for the
hunter. Besides the strong military-style belt-clip
and nap-latch, the carry case has an innovative flap
that covers the ocular lenses, protecting them in
wet or dusty conditions and obviating the need to
fiddle with lens caps.
A feature that I’ve never really
taken to in the past is individually focused
eyepieces — and for all the wrong reasons. I had
previously used only inferior products with higher
magnification and very limited depth of the
field-of-focus. When focusing on, for example, an
antelope in a herd — only those animals in the
immediate vicinity of the targeted antelope will
also be in focus — those that are more than a few
yards this side or beyond it will be out of focus.
I insist on perfectly sharp images at all distances
and have never believed the advertising blurb, “Once
in focus always in focus”, as this is not physically
possible (as is readily obvious with a high
magnification). However, I had to eat humble pie as
I realized why the designers had decided on a 7x
magnification rather than an 8x. Now the whole
design concept fell into place. With a 7x power,
the depth of field is increased tremendously
resulting in the user only having to remember two
settings, one for distant viewing arid the other for
closer ‘bushveld’ conditions.
For instance, when focused at
infinity everything from about 75m to infinity is in
sharp focus, and when set down a notch, everything
from about 25m to about 1OOm is nice and sharp. If
they are set for close range and there’s suddenly a
demand for distant viewing, the adjustment is quick
and smooth and with a little practice takes no time
at all. However, once set, they cannot easily be
knocked out of focus inadvertently. So the two
features, namely lower magnification and
individually-focused lenses, which I had thought
would detract from their usefulness, proved very
beneficial, and certainly help make these little
binos functional and appealing to the hunter.
Designed for military use, these
lightweight 7x28s are rugged, waterproof (to 2m),
and constructed to survive military drop tests of
1.8m onto turf. They are attractively protected
with a rubber coating in shades of camo, and come
with the option of a ‘midot’ graticule to assist in
determining distances. By not having a central
focusing wheel or lever, with complicated and
vulnerable internal elements, they can be made
watertight and reliable very cost effectively.
After using them for a few days In varying
conditions in the Drakensberg, glassing for baboons
and eland, I wouldn’t have them any other way. I
concluded that this military concept is highly
suitable for the hunter, and its fiddle-free
focusing facility can save precious seconds when the
game is skittish. A further benefit of reducing the
magnification from 8x to 7x is the increased size of
the exit pupil, which allows for the steadier and
brighter images so advantageous if you are prone to
tremble after exertion. The exit pupil is that tiny
circle of light that one sees in the ocular lens
when the bino is held at arm’s length. To establish
this diameter, divide the objective (front) lens
diameter by the magnification. In this Instance
divide 28mm by 7 and the answer is 4mm — the same as
that of an 8x32 binocular which is nearly twice the
size and weight.
To have the abovementioned
advantages, plus compact dimensions, by forfeiting
only one power of magnification makes absolute
sense. The makers of quality marine binoculars
recommend either 6 or 7x because these are
invariably used from a moving deck, and although
used for scanning distant horizons, steadiness is
more important than magnification. The ocular
lenses are also larger than normal to further
enhance this aspect. The Lynx’s lenses were tested
for chromatic (colour) aberration, coma (peripheral
cloudiness) and vignetting (peripheral shading) with
very good results. Sharpness and clarity tests
(reading tiny print from a distance) were done with
the binoculars tripod-mounted to obviate
unsteadiness. In this test the 7x28 managed 9.25m,
while a pricier 8x40 just managed to squeeze in at
10.3m.
Besides panning very nicely, they
also passed ray ‘Southern Cross test’ whereby the
four main stars forming the Southern Cross must fit
into the field of view simultaneously. If a
binocular’s field of view is smaller than this, you
may have difficulty orientating yourself or quickly
‘picking up’ the quarry in bushy surroundings. For
a full field of view for spectacle users, the Lynx’s
eyecups can be folded back simply by pushing on them
with the palm of the hand (Zeiss style).
The suggested retaIl price of R2950
with the rangefinder graticule, and R2750 without
it, is excellent value for money, and in this price
range I cannot think of a better-handling and more
user-friendly binocular for hunting or marine
requirements, considering it is fully waterproof.
Dust, mud or saltwater spray can simply be rinsed
off under a gentle stream of tap water, reducing the
risk of scratching the lenses. Sure, they are not
as sharp or as bright as their expensive bigger
cousins, but you will never feel inferior with these
little ‘Lynx Hunters’. Improvements? Only one—I
would suggest ‘click stop’ eyepieces.
The fact that many astronomers use 7x
binoculars to gaze at the heavens must have a
message in it somewhere. After a tiring night
studying the heavens through powerful telescopes,
one famous astronomer would take a break and go
outside to enjoy the sheer magnificence of the night
sky — using his 7x50 binoculars to reveal the true
splendor of the heavens rather than that of a single
object as seen through a telescope.
These glasses are backed by a
five-year guarantee with local importers who have
the expertise and facilities to repair them if need
be. Needless to say, my PH friend has ordered a
pair. |
