BINOCULARS

Hi guys,
The big brown truck and the nice man that brings goodies to the house stopped yesterday with a package from Cabela’s.
I was deprived from sleep for the five days that it took between order and delivery, but finally the Nikon Monarch ATB 8x40 binoculars are here, and I will sleep soundly tonight.



Although I have quite a few binoculars in my safe, I don’t have nearly as many of them as I do flashlights (most of you know me as the crazy guy that owns all those flashlights); but fear not, I am getting there.
So it occurred to me that I should make a post about binoculars for those that are bored of hearing about my lights.
I had owned quite a good amount of binoculars since I bought my first as a 15 year-old with an itch about optics. I even owned an expensive Zeiss when I was single and didn’t had a family to take care of.
And I am here to tell you that the quality, brightness, sharpness, and durability of the new binoculars now on the market; it is better than ever.
Not long ago, if we wanted all these features in a good binocular the choice was between spending a thousand in a Zeiss, Swarosvki, Leica or Minox or looking for good Porro prisms in the Nikon or Pentax lines.
But since a couple of years ago, the Japanese starting coating the roof prisms of their binoculars with Phase Coating, and the sharpness and definition of their roof prism binos had increased to the point to rival the European imports from the big four, and all at very modest cost.

Take, for example, the Nikon Monarch ATB (All terrain binocular) 8x42 I just received, or my Pentax DCF WP 8x42 that I bought last year.




All lenses are fully multicoated (that means all surfaces, not only the glass to air surfaces) prisms are phased-corrected and have mirror-coated lower prisms (not cheap aluminum). They have blackened tubes to avoid reflections and are waterproof and fog proof; they have a nice outer coating of rubber (silent) and very good ergonomics. I particularly like the twist eye cups for eye-glass wearers and the ample eye relief: no problem using it with my glasses and instant acquisition of the picture even with glasses on.



All that can be said for the Nikon Monarch can be said also of my Pentax DCF WP 8x42, except for the weight: the Nikon is lighter at 22 ounces but I don’t know how much my Pentax weighs until I get a new battery for my fish scale.

I like the approach of securing the objective caps to the body of the binocular that the Nikon uses as well. I had to get creative with the Pentax and cook up something home-made to hold the caps to the binocular body.
I did the usual checking for good prisms by holding the binos a few inches away and looking at the light spot in the ocular lens, nice and round without any hint of flattening, just like I was expecting. I checked collimation by holding it a few inches away and pointing them at the yellow line in the road, straight and sharp with not sign of being distorted.
To test the sharpness and resolution most people look from the inside to the outside thru an open window, and most binoculars will perform well under those conditions. I look for a dark corner in the room and try to read some labels or a newspaper print set for the occasion; that is what separates the mediocre from the good or great binoculars.

As the Nikon and the Pentax are so the same in quality I tried to spot any optical differences between them by perching one on top of the other and alternatively looking thru them. After several minutes of this I have to admit that they are both the same optical quality as far as my eyes can tell, without resorting to an optical laboratory.



I have looked thru many Swarovski and Zeiss lenses, (I hunt the stores) superb optical quality in those glasses. I can tell you for sure than the new Nikon and Pentax are almost the equal of those expensive brands; that I only paid just over $300 with shipping for such a superb glass as the Nikon still amazes me.

Kind regards,

NIGHT OWL 4X NIGHT VISION
COMPACT BINOCULARS

I have owned this night vision binoculars for about seven years. They are made in Russia and feature the first generation of Russian intensifiers tubes that are so popular lately.

It is my understanding that the Russian tubes were not of new manufacturing, but surplus tubes were released into the market. My first unit of these binoculars had a tube that was much dimmer than the other; however the Night Owl Company quickly exchanged them at my request.

As you probably you already know, unlike the older infrared night vision technology, the intensifier tubes do just that: intensify the light that is available (up to 30,000 times according to the instructions) and if ambient light is present, it doesn’t depend on the attached infrared emitter that is placed on top of the binoculars as an extension of the center pivot.

The binoculars enlarge the image transmitted to the oculars by 4 times. Not exactly a long-range pair of binoculars, but really very useful at short distances.




The Infrared emitter has a separate button for its operation. It is not really full infrared (infrared light is invisible) but a good amount of red shows out of the lens of the tube, making the fact that you are watching with them noticeable to humans. For game it really doesn’t matter, as most animals are blind to the red spectrum of light.
When used with a truly blind infrared powerful source (I just rigged a BOREALIS 1050 lumens flashlight ~2 million candlepower~ with a surplus Israeli jeep infrared filter) the binocular can easily “see” 300 yards away in total darkness.

The glasses weigh 31 oz., which isn't bad for a binocular that is 6 ¼ long by 6 ½ wide and 1 ¾ thick. The barrels of the objective adjust for focus individually. The adjustment is very smooth and easy to move; likewise, the ocular also has an adjustment that is individual to each eye, and it is not a center focus adjustment wheel, like in regular binoculars.
The metal screw in caps covering the objectives have a little pin hole to limit the amount of light that will enter if the binoculars are used during the day, which is mostly done to make adjustments for distance and focus previous to the projected night use. Those metal caps are noisy to unscrew or screw them, so if you're using them when game is near, I recommend replacing them with Buttler Creek or similar spring loaded binocular caps.
The power is supplied by a Lithium 123 3 volts battery that is loaded from the rear where the hinge is in the binoculars. These batteries are more popular than ever, thanks to the amount of tactical flashlights that make use of them.
This is better than the present problem I have of trying to find a number 1 battery for my Israeli surplus infrared night vision goggle (and by the way, if one of you readers know a source for such battery, please let me know).

For a first generation unit, the Night Owl 4x Compact is a very good binocular, well thought-out in its design and construction, with rubber covering to make gripping easier and to deaden game spooking noises. When I first bought them my son was 10 years old and interested in watching game, so we spent a few enjoyable nights watching deer eating apples at the tree and watching over a bear bait in upper Maine, just to see what was showing up. To all you fathers out there, those kinds of memories can last a lifetime and tend to be the greatest ones, especially when that same son is now a college student and interested in watching other types of game. So cherish them well.
Best regards,

BINOCULARS 8 X 56

Hi guys,
This post will be of little help to those looking to buy a binocular in the 8 x 56 size, because what I have here is a little outdated, my Tasco 8x56 is about twenty seven years old and my Pentax DCF 8x56 about six.
Still let me talk a little about them so you can see what job the monster can do.

Great improvement has been made lately, especially in the phase correction of prisms that has sharpened the image considerably.
These big and heavy binoculars together with the 7x50 are called night glasses and they have a very specialized job of taking advantage of the last available light at dusk and before dawn to see game in their habitat, they are mostly used by European hunters with their liberal shooting hours and used mostly from machans or hotchsit where the bulk and weight are of no consequence.

In the eighties I was involved in doing some research in the habits of black bear, I have seated many times at bait stations armed only with these heavy binoculars, learning the feeding peculiarities and the pecking order of the American black bear.

Although I had lusted over getting a Zeiss 8x56 I had to conform myself with the Tasco 8x56 for many years until I found a brighter binocular in the Pentax DCF.
Brightness is a function of many things (including the objective diameter) the more prominent of them is quality of glass, the better factories use heavy and expensive Bak4 glass in the prisms and extra low dispersion glass for color correction and aspherical lenses that have multicoats of anti reflection coating as much as seven times; it looks like the Pentax binocular uses several of the new techniques to be brighter and sharper than the Tasco 8x56.


Although my Pentax DCF is not corrected for phase distortion at the prisms, it is extremely sharp and bright; the new binoculars in the line of Nikon, Pentax, and others are, being made even better by the addition of phase correction in the prisms.
In my Pentax the correction for eye relief for eye glass wearers is made on the old style fold down rubber eyecups, so you get only fully retracted or fully extended eye cups. I am very impressed with the new system in the Nikon line of helical retracted eye cups and in the Pentax line with the pull up or down eyecups that have come out in the last few years.

My six years old Pentax DCF 8x56 has the objective and ocular caps not attached in any way to the body of the binocular, I had to get creative and cook something home made with a ribbon and some Velcro to have those caps at all times together with the binoculars, new binoculars in the Pentax line will be better in this regard (at least they have a solid ocular lens cover) and I am impressed with the system of retaining the covers that Nikon is using now.




I pulled both binoculars from the safe a few days ago and compared the brightness and sharpness by putting them in the tripod perched in top of each other and taking alternate peeks throughout them at a ADT sign that is in my neighbor house, located at 50 yards from the tripod (by laser rangefinder) it reads in very small letter “protected by” ADT in big letters and again in small letters “security systems”.




Both binocular let me read the sign and the small letters, but the Pentax was sharper than the Tasco and the quality of glass on the Pentax resolved much better when the light was falling down.




At dusk when other binocular have quit, the big 8x56 continues to show you a clear picture. As I see its utility is for those that are willing to carry them in a back pack to use only after the daylight binoculars carried in the neck have quit showing detail.

I don’t think many of these big 8x56 are sold, many people from hunters to bird watchers prefer top carry the compacts 8x42 that are lighter and less bulky and can show birds or game quite well until just before dusk, still I am writing this so everybody is aware that they exist and that they perform a very special function.

Kind regards
