Tips For Buying A Pair Of Binoculars
You have tickets for the NASCAR or F1 races, and you want to get the most out of the action on the track. Naturally, you would think of buying a pair of binoculars to catch the action. But which binoculars should you buy?
Nowadays, binoculars are designed for specific purposes. There are binoculars for watching sporting events or concerts, birdwatching, golfing, hunting,surveys or sightseeing. Binoculars also have a bewildering range of features such as lightweight, waterproofing, fog-free lens, sharper and brighter images. The larger objective lens diameter would confer brighter field view while multilayer-coated lenses deliver bright, beautifully defined images. Those used for hunting, golfing or survey, would come with distance indicators in the form of a laser range finder. 
For a general purpose binoculars, look for one which is lightweight, compact and waterproof. For a cheap pair of binoculars below $200, you can consider the Bushnell Binoculars. It offers good image quality although the body construction is not the sturdiest. Nikon has a range of binoculars in the Travelite Ex series costing below $300. These are light and compact, ideal for lugging along on holiday, to a concert or the race. If you do not mind the weight, the Nikon Action VII series and Action VII Zoom series can be bought for less than $200. Binoculars with laser range finder cost set you back about $500-600.
Binoculars Specification
For viewing car races, go for a pair which is 8x42 or 10x42. The first digit refers to the zoom factor (i.e. 8 times or 10 times the magnification) and the second numbers refer to the brightness of the image. In general, the bigger the numbers, the better. Bigger first digit gives you larger magnification and larger second digit provides brighter images.
However, having higher magnification also means a narrower field of view. If you opt for a 20x42 binoculars, you will be able to see the driver's head and face, but not much else. For viewing fast moving action, you may get dizzy. A brighter image is, of course better but such binoculars would be bulkier and heavier. So it depends on your preference.
If you have a higher budget, you can consider Nikon Binoculars for up to $1000. If you can fork out $2000, go for Leica Binoculars with their better optics. For the top of the range, $4000 will buy you the best binoculars from Swarovski.
Frankly, for NASCAR or F1 actions, you don't really need a binoculars.
