Nikon continues to press ahead into the future with
new and innovative products and features in all of their lines. I have owned
several rangefinders and have tested even more over the years and the latest
installment from Nikon, the Monarch Laser 800, tops them all.
The test unit was received early last winter and the
evaluation follows:
General
The Nikon Monarch Laser 800 sends out invisible infrared energy pulses that hit
a target and are reflected back to the unit’s laser detection receiver. At that
point high tech circuitry takes over and instantly calculates distances through
the time it took for the emitted energy pulse to return. Nikon lists the
following items as those that will result in the best range and accuracy:
Nighttime use, Cloudy weather, brightly colored target surfaces, highly
reflective target surfaces, targets with shiny surfaces, large size targets and
targets that are 90 degrees/perpendicular to the user. Some of the target
characteristics that hinder range and accuracy, other than those opposite of
the listed items above, are: A moving target, snow, rain, fog, target with
pronounces depth and any target that has an object moving in front of it.
Nikon features
their Tru-Target (TT) Ranging System on the Monarch Laser 800. Tru-Target
utilizes two primary modes of operation; First Target Priority Mode and
Distance Target Priority Mode. The Distance Mode determines the range to the
farthest target of those that are being measured. In other words, if that big
buck you are trying to measure has some limbs and brush around him the unit
will only pick the buck up and not the obstructions in front of him. The First
Target Mode allows for measurement of a small, single target such as a tree or
lone animal.
The Laser 800
has two operation buttons located on the top of the unit. The power button,
located toward the back nearest the user, is used to turn the unit on. Once
powered up you will see three things inside the viewer including the battery
condition indicator, aiming reticle (cross-hairs) and units of measurement in
yards or meters. If the power button is depressed again the unit will start to
measure.
To select
between the First Target and Distance modes, after the unit is powered on,
simply depress the mode key and then immediately depress the power key, holding
them both down until the mode changes. You can tell when the mode changes while
looking through the viewfinder and a symbol appears or disappears that looks very
similar to the “G” on the Green Bay Packers helmets! That symbol denotes the
First Target Priority mode.
To change
between meters and yards, once the unit is powered on, simply depress and hold
the mode button for 1.5 seconds. In the upper right hand corner of the display
you will see either “YD” for units in yards or an “M” for meters. The Monarch
Laser 800 also features a backlight for its LCD display that is activated by
depressing the mode button for LESS than 1.5 seconds. This backlight allows for
distance measurements in little or no light situations.
Another feature
of the Monarch 800 is a 20 second continuous measuring function. Once the power
is on this function is turned on if you depress the power button continuously.
The best way I can describe it is the difference between taking a single
picture with your digital camera or turning on its mini-movie feature that runs
for 20 seconds. When in this mode you can move from target to target taking
different measurements.
Nikon’s Monarch
Laser 800 is essentially a monocular that is outfitted with 6x magnification
multi-coated optics, 21mm objective lens, and a 6-degree angular field of view.
The 800 also sports a comfortable focusing extension rubber eyepiece cup. Each
Monarch unit is nitrogen purged and O-ring sealed for waterproof and fogproof
operation. Distances can be ranged from
11 to 800 yards in +/- ˝ yard increments. Other features include a long 18mm
eye relief, tripod mount, high-contrast black LCD display, optional neck
lanyard, belt case, automatic power shutoff and a compact size for easy
handling. The unit measures 5” x 2.8” x 1.5” and weighs 7.4 ounces.
Testing
As with all of
my reviews I first performed an initial quality/workmanship check on the unit.
The test unit, like all of the other Nikon products I have ever tested, was
absolutely flawless in every way. No marks, scratches, mis-fitting parts or any
other material or workmanship defects were found on the lenses or housing.
Accuracy was
tested up to 50 yards by actually measuring out the distance, in ˝ yard
increments, with a tape measure and beyond 50 was measured at a local shooting
range. The Monarch 800 was on the money at every ˝ and full yard out to the
50-yard marker I had set. At the local shooting range there were markers set at
50, 75, 100, 150, 200, 300, 400, 500 and 600 yards. Measurements with the
Monarch 800 were within a few yards of each. Within a few yards because my
position at the shooting benches varied somewhat and they did not have a clear
“starting line” marked anywhere that I could see. When measuring distances of
200 plus yards freehanded I came to appreciate the continuous measuring
feature. The same was true when trying to measure smaller targets at almost any
range. It is a big plus – no more trying to hold steady for that quick
snapshot!
The best test
was a season long use. I used the Nikon Monarch Laser 800 on every hunt I was
on in 2005 including a Missouri turkey, an Ontario bear hunt with Missinaibi Outfitters and a host
of whitetail hunts in Pennsylvania and Ohio. Just about every
weather condition was experienced at one point or another during those hunts
throughout the year and the Laser 800 performed perfectly in all instances. The
waterproof/fogproof claims were challenged and met, the measuring modes were
tested and found to be useful and in general the unit was easy to use.
Nikon’s Monarch
Laser 800 is a top-notch, “best in class” rangefinder! Their engineers, who
must be hunters, provide a solid unit with great hunter friendly features that
are easy to use. What more can a hunter ask for?
