Choosing the Right Running Shoe

Written by Ryan Fyfe

Continued from page 1

Motion Control - The motion control category is for runners who really need support in a running shoe. Extreme pronators and overpronators can take advantage of a Motion control shoe, as well as a runner with weak ankles and other foot problems that would benefit from a shoe with a lot of stability.

Of course with only three categories like I mentioned above, there is a lot of room for variation. This is only meant to be used as a quick guide for things to look for in running shoes. I would recommend visiting a running store and having an employee look at your feet to give you a good idea of what category your feet fit in. If you have serious foot complications like extreme pronation, fallen arches, etc I would recommend visiting a foot doctor, as running shoes by themselves might not be enough. You could require orthotics, or even just simple strengthening exercises to get and keep you on your feet.

How to Make Unbelievable Shots Using Handgun Scopes

Why are these numbers so important? Because not only will it tell you whatrepparttar magnification ofrepparttar 139272 scope is but alsorepparttar 139273 diameter ofrepparttar 139274 exit pupil once you knowrepparttar 139275 formula.

Before I get into how to calculaterepparttar 139276 exit pupil, I’ll bet you’re wondering what an exit pupil is. This may get a little technical so please bear with me.

Here’s how it works. A scope gathers light overrepparttar 139277 face of its front or objective lens and concentrates it out intorepparttar 139278 eyepiece in an area calledrepparttar 139279 exit pupil.

The exit pupil of your scope should matchrepparttar 139280 pupil size of your eye as closely as possible (or just a little larger) to get maximum low light performance and prevent scope blackout. You calculaterepparttar 139281 exit pupil diameter by takingrepparttar 139282 objective lens diameter (front lens closest to your target) and dividing it byrepparttar 139283 scope power.

For example, a scope with a 20mm objective lens and a power magnification of 2 will have a 10mm exit pupil. 7 to 8mm is aboutrepparttar 139284 maximum size thatrepparttar 139285 human pupil will dilate in low light, so this scope will work well under low light conditions. A smaller exit pupil would not deliver as much light torepparttar 139286 eye asrepparttar 139287 eye is willing to accept, however, a large exit pupil means thatrepparttar 139288 eye doesn't have to be as precisely centered behindrepparttar 139289 scope to receive a full image.

For adjustable power scopes, 3-9x40mm for example, you getrepparttar 139290 exit pupil based onrepparttar 139291 power setting ofrepparttar 139292 scope. For example: 40 divided by 3 = 13.33mm exit pupil and 40 divided by 9 = 4.44mm exit pupil. As you can see,repparttar 139293 higherrepparttar 139294 magnification,repparttar 139295 smallerrepparttar 139296 exit pupil, hencerepparttar 139297 lowerrepparttar 139298 light gathering capabilities at higher magnifications.

When talking about light gathering capabilities, you’ll want your exit pupil to berepparttar 139299 same diameter or just a little larger thanrepparttar 139300 conditions you're usingrepparttar 139301 scope in. For instance, if your eye’s pupil is dilated to 5mm, andrepparttar 139302 exit pupil ofrepparttar 139303 scope is 7mm, then you have 2mm of leeway before your eye position behindrepparttar 139304 scope becomes critical.

Ifrepparttar 139305 exit pupil ofrepparttar 139306 scope is smaller thanrepparttar 139307 diameter of your eye’s pupil, you’ll start to encounter problems seeingrepparttar 139308 full image of your target.

Just as a frame of reference,repparttar 139309 human pupil is normally dilated to about 5mm in standard light, 2-3mm in bright light, and 7-8mm in low light conditions.

Whew… I know my description was a little technical, but knowing whatrepparttar 139310 exit pupil is and how it works will help you determine how to best utilize your scope.

You might also be wondering howrepparttar 139311 exit pupil calculation, light gathering characteristics, and scope magnification tie in with extended eye relief? Just remember, for EER handgun scope applications you’ll be holding your scope anywhere from 5-30 inches away from your eye. This can be a significant distance if your scope doesn’t illuminate your target well enough andrepparttar 139312 position of your eye is not aligned withrepparttar 139313 exit pupil. These have a significant affect on EER, making it difficult to get off an accurate shot if not taken into account.

And… speaking of accurate shots, there are a few handgun scopes I recommend to give yourepparttar 139314 best chance of accomplishing those shots.

I think some ofrepparttar 139315 best handgun scopes for Extended Eye Relief and light gathering capabilities arerepparttar 139316 Nikon EER Monarch series,repparttar 139317 Leupold FX and VX series, andrepparttar 139318 Burris LER series. All three companies offer exceptional choices in optics as well as full lifetime guarantees. They’re rugged and durable and 100% waterproof. They have unmatched lens coating systems which excel in brightness, clarity, and contrast.

Few companies are able to stack up, however, you’ll have to makerepparttar 139319 best choice for your shooting application and go withrepparttar 139320 scope and company you feel most comfortable with.

They’re notrepparttar 139321 cheapest scopes, but they’re best overall value and definitely worthrepparttar 139322 investment.

Hopefully I’ve clarified questions you might have had about scope definitions and how to calculate critical components of a scope. Now, with this information, you’ll be armed withrepparttar 139323 knowledge you need to make a wise EER scope selection.

Oh… one more thing. Usually,repparttar 139324 amount of eye relief and magnification is listed inrepparttar 139325 specifications by most manufacturers, so you should be able to get a good feel for what you need after applyingrepparttar 139326 knowledge you’ve gained from this article.
