The choice of a telescope

!±8± The choice of a telescope

Hunting for white-tailed deer, mule deer, Elk, Moose, Black Bear or Coyotes need a quality telescope. The following tips can help you choose.

First, there is a high quality frame that fits your budget, buy the best you can afford. You'll never go wrong buying the best, but we all have pockets.

Consider first the quality of the brightness of the scope. To do this, to find the larger end of the scope. It is measured in millimeters. The larger the lensThe light is more to collect it. If you are hunting in the early morning or late at night (if not you should), you must gather as much light as possible. An area will be similar to the 9x40 size. This means that you will see the object 9-fold magnification, and 40 would be the objective. Here you can collect the light. The larger the lens the more light is collected.

Now the above example, at a fixed magnification scope. Opt for a telescopic sight that is adjustableMagnification. An area, such as 4-9x40 means that it can be adjusted from 4 levels of magnification of 9 times. The set of 4 power scope will give you wide field of view (FOV). If you shoot at a moving target and then lower magnification is best. It makes it easier to track moving target. The higher the magnification, the narrower the FOV. Consider the function of zoom on a camera that works the same.

Next make sure that the frame of a plurality of coated lenses. This means that each lens in theScope has several layers to reduce the loss of light, gives a higher contrast and reduces glare. There are different types of coatings used. The type of coating depends on the manufacturer.

Next, you should have your new air displacement range and elevation adjustments. These are incoming calls on the top and side projections. The top setting, or adjust the height up and down. The page or control is usually left to right on the right side of the scope. Each ofmay change with the cap and turning with your fingers. Every click is usually ¼ "to 100 meters. These shots can be heard quite easily.

The next thing to note is the size of the exit pupil. What would be the end of the scale near the eye. Once again, the size is larger the exit pupil is the image brighter. It is usually possible to increase the share of power through the lens of the exit pupil size to find. A 4x40 would then give you a 10 mm exit pupil. In otherWords, the size of the column of light from the lens exit pupil.

An important consideration for me personally is the viewing distance. Eye relief is, as the eye can see by the end of the scope and still give you a field of view (FOV). With a long eye relief over the end of the range. If you're too close, causing the gun can recoil in order to hit your eyebrow was bad for a small incision, or at least a bruise. If you find an area with a relativelyshort eye relief, make sure it has soft rubber around the end of the field. This will be a little 'more protection from the recoil.

Locate an area to be sealed, waterproof and fog proof, one that is resistant to scratches. If you can go through all the brush size zero. And by the way, if you delete or at least kick your application, you should look again to make sure that the chances of a trophy is his black met.

Finally, you have to hand the shotgun mounted on aProfessional. If you buy the new framework of a merchant of quality, are free to assemble your order.

I will not go into the interior of the goals. What I wrote is the amateur version of the election of a new rifle scope.

My personal preference is a 3-9x40. I think this is a matter of great for the big game.

There are many brands available that well you should be sure to buy. Here is a partialList.

Mil Dot reticle with a telescope with your

!±8± Mil Dot reticle with a telescope with your

Many manufacturers of rifle scopes reticle can have a set of one or the other. Perhaps the most common supervisory goal Reticle Mil Dot reticle. This article describes how to use a Mil Dot reticle. With other systems of dose-finding purposes and similar benefits can be seen from this description.

Geometry of MilDot

A grid composed of dots arranged with the viewfinder MilDot evenly on the horizontal and vertical. Each point ofLattice is a milliradians in diameter. Without getting bogged down in geometry, is an angular measurement in radians of a circle where the radius of the circle corresponds to the length of the arc of the circle. Milliradians is one thousandth of a radian.

With the geometry above, then we can understand how the range of millions conclusion applies to the letter. If we reach the center of a circle, to understand and take into account the object's distance from the radius of the circle, then weunderstand that the point includes a circular arc. Now, knowing that milliradians is one-thousandth of the radius, then the formula we can easily drive a mil dot for thousands of units use the same. That is, a shipyard in a thousand meters, one meter to 1000 meters, one centimeter over a thousand inches, etc.

Focal Plane

Scopes have two focal planes, the so-called first and second focal planes. Reticulum may be either first or second focal planes are located. If 'Grating in the first focal variable magnification range plane is set, the mil dot reticle will be used at any magnification, it will shrink or grow the network with the expansion. If the lattice is placed in the areas of the second focal plane, the grid is determined by the size of the magnification. If this is the case, the grid in order for the maximum magnification is calibrated. It is often useful to contact the manufacturer or search for informationhas come to be sure, but the test system for measuring distance to know its purpose is to reveal the calibration target with the telescope.

Practice, practice, practice

Speaking test range finding system, a lattice grid to measure the distance it takes practice and lots of it. Unlike the understanding of the use and size of the grid, you must know the size of the target for comparison purposes. It 'important targets at distances of known size you think you want to adjustRangefinder reticle and look through the telescopic sight. Then check what you see. Does it work? Is it useful? It does? Great, now the practice even more.
