BUSHNELL  H2O  10x25  WATERPROOF  FRP  BINOCULARS 131006  AND  131005

            If you are in the market for a pair of inexpensive binoculars that you can safely use outdoors without fear of getting them wet or easily damaging them, you might want to seriously consider the Bushnell H2O 10x25 Waterproof FPR Binoculars, Model 131005.  There is also a camouflage version of these same binoculars that are Model number 131006.  Both Model number 131005 and Model number 131006 are virtually identical, except that Model number 131005 is black in color and Model number 131006 is a camouflage color.  These binoculars are versatile and rugged, and yet they have an entry level price tag that won't break the bank.  Bushnell is a world leader in optics, and they have taken some of their higher level technology and put it into the Bushnell H2O 10x25 Waterproof FRP Binoculars, Model 131005.  Read on and see if these binoculars sound like something that you might be interested in looking into the next time you are considering making a purchase of a set of binoculars.

            Price is always an important consideration in making any purchase decision, and as such I would like to discuss the price of the Bushnell H2O 10x25 Waterproof FPR Binoculars 131005 right up front in this review.  The Bushnell H2O 10x25 Waterproof Binoculars have a list price of $69.95, but they can be readily found selling at a discount from some of the larger national optical equipment stores for a price of about $48.98.  A word of caution however is called for whenever making a purchase over the Internet, as some dealers will hit you will shipping and handling costs that can substantially bring up the overall price of these binoculars by another $7.00 to $10.00.

            I would now like to discuss some of the specifications of the Bushnell H2O 10x25 Waterproof FPR Binoculars 131005. Since the cost of the Bushnell H2O 10x25 Waterproof FRP Binoculars have a relatively modest price tag, it is likely that the average consumer who is considering purchasing these binoculars is likely to be a novice user, and as such, the novice user would not be expected to know and understand all of the technical jargon that goes into a description of the various specifications that differentiate one pair of binoculars from another.  Bearing this in mind, I shall endeavor to avoid jargon and keep the use of technical terms to a minimum.  Whenever there is a need to use technical terms, I shall endeavor to explain the meaning of these terms in clear and simple to understand language.

           A good place to start would be to discuss the magnification factor or the Bushnell 10x25 H2O Waterproof Binoculars.  The Bushnell H20 8x25 Waterproof FPR Binoculars 131005 have a magnification power of 10 times.  This is an easy fact to understand.  The number "10" in the descriptor 10x25 refers to the magnification power of these binoculars.  It means that an object will appear 10 times closer when viewed through these binoculars than when it is viewed by the unaided eye.  Thus an object that is 1000 feet away will appear to be 100 feet away when viewed through these binoculars.  The number "25" refers to the size in millimeters of the objective lenses, which are the larger lenses on the other side of the binoculars which face the object that is being observed.  The size of the larger lens or objective lens has nothing to do with the magnification power, but its size is important as regards the capability of the binoculars to display a bright clear image in lower light conditions.  In bright sunny light, even a pair of binoculars with small objective lenses, such as a 25mm to 35mm, will tend to yield a relatively sharp and bright image.  However, in lower light conditions, a large objective lens serves to increase the amount of light that is available to view the image, and thus all other things being equal, a set of binoculars with large objective lenses will yield a brighter image to the viewer.  Thus, when using the Bushnell H2O 10x25 Waterproof FPR Binoculars, one is going to get the best and clearest image in brightly lit conditions, such as during the day in an openly lit setting.  These would not be the best binoculars to use in low light conditions, such as a shadowy forest, or at dusk, or for viewing objects in the night sky.
           
           Although having a magnification of 10 times may not seem to be a high degree of magnification, it is actually quite sufficient for most purposes, especially if these binoculars are being used without the assistance of a tripod or other stabilization device.  An important point to consider when purchasing a set of binoculars is to keep in mind that a magnification of 10 times is considered by most people to be the absolute maximum that a person can use a set of binoculars with when they are being used in a hand held situation.  At about a magnification of 10 times, the hand shake of the viewer simply becomes too great to allow for precise and sharp viewing of a small distant object, as it will appear to be jiggling all over the place.  Any one who is knowledgeable about binoculars will vouch that it would be advisable to use a tripod or some other type of stabilization device when using a set of binoculars that have the magnification power of above 10 times.  Thus, a magnification of 10 times, such as the Bushnell H2O 10x25 Waterproof Binoculars have, is a very reasonable level of magnification to have for hand held use.  This is good to keep in mind for another reason, and that is that these Bushnell H2O 10x25 Binoculars do not have a built in tripod adaptor.  This may be something that a consumer who wants to mount their binoculars on a tripod must also be mindful of when making a purchasing decision, as this could be an important consideration for a potential user, especially if they do not have very steady hands.
            
            There are other things besides the size of the objective lenses that are very important to consider when discussing the ability of a pair of binoculars to yield a bright and clear image, and that is the type of antireflective coating that may or may not be applied to the viewing optics of the binoculars.  The Bushnell H2O 10x25 Waterproof Binoculars have "multi-coated optics."  This means that there are multiple layers of antireflective coating on at least one of the surfaces of the lenses.  This is an important point to understand.  When light hits a glass surface, some of it is reflected, and some passes through the glass.  The more light that passes through the glass, the sharper, brighter, and clearer the image will appear to the viewer.  Thus, when a pair of binoculars has a coating of antireflective materials, such as Magnesium Fluoride, less light is reflected off the lens surface, and more passes through to the viewer, which results in a brighter image.  Simply put, multi-coating reduces the reflectivity of light, and the result is a sharper and brighter image. 
           
            The Bushnell H2O 10x25 Waterproof Binoculars have a BAK-4 Roof-Prism design.  Prisms are used in binoculars to reduce the physical length of the body, as compared to a telescope, and secondly to correctly orient the image for the viewer.  In a Roof-Prism design, the prisms overlap closely with each other, and by virtue of very precise mathematical alignments of different angles which allow for reflection of the incoming light, binoculars with a Roof-Prism design have a very slim and straight line appearance, like the Bushnell H2O 10x25 Waterproof Binoculars have.  This is because the lenses and prisms are set in a straight line, which results in a simple streamlined appearance.  In a Porro-Prism design, the objective lens is offset or to the side of the ocular lens, and there are two prisms set at right angles to each other which reflect the incoming light three times.  A Porro-Prism design is much simpler than a Roof-Prism Design.  A Porro-Prism design tends to yield a brighter image than that of a Roof-Prism design.  However, when designed and engineered properly, either or both of these designs are fine. The Bushnell H2O 10x25 Waterproof Binoculars 131005 also use BAK-4 prisms, which are considered to be higher quality than BAK-7 prisms, and they tend to yield a brighter and sharper image than most lesser quality binoculars that use BAK-7 prisms.  The use of BAK-4 glass is a very desirable feature of these particular binoculars.

            The Bushnell H2O 10x25 FRP Waterproof Binoculars are both waterproof and fogproof, and as well as being both nitrogen purged and o-ring sealed.  Fully waterproof binoculars are relatively impervious to the issue of things like temperature and humidity changes because their inner workings are airtight, and thus they will not fog up when you are outdoors.  They also are easy to clean and can be washed off without fear of getting water or moisture inside of them.  This makes the Bushnell H2O 10x25 FRP Binoculars suitable for just about any outdoor activity such as hunting, camping, skiing, or snowmobiling, and it is this feature that makes these binoculars especially suitable to any type of marine usage as well, such as sailing, canoeing, kayaking, or just a trip to the beach.  Even if these binoculars were to accidentally be dropped in the water, they would still remain dry and free of moisture on the inside.  These binoculars are also coated with a non-slip rubber coating, which serves to prevent slippage, and also provides a bit of shock absorption should they accidentally be dropped.

            The Bushnell H2O 10x25 Waterproof Binoculars have a field of view of 330 feet at 1000 yards.  O.K., that sounds nice, but what does the term "field of view" or FOV actually mean?  This is actually a simple concept to understand.  Imagine you are looking at two different people located 1000 yards away.  If the person on the left is separated from the person on your right by 330 feet, and both are visible at the edges of the binoculars, then your filed of view would be 330 feet at 1000 yards, which is just what the Bushnell H2O 10x25 Binoculars have. This is a very reasonable field of view for general viewing.  In general, higher powered binoculars give a lower field of view than lower powered binoculars. The Bushnell H2O 10x25 Waterproof Binoculars are in the compact size class, and weigh in at 13 ounces, which is not very heavy at all, and should present no problems for the average person, or even young child to deal with.  These binoculars are not only light in weight, they also fold down and inward for ease of storage and transportation, and they are considered to be compact binoculars.

            So who should consider purchasing the Bushnell H2O 10x25 Waterproof Binoculars?  These binoculars would be suitable for almost any outdoor use, such as for hunting, camping, skiing, boating, snowmobiling, bird watching or almost any general outdoor enjoyment of nature.  However, once again, because of these binoculars have an objective lens that is only 25mm, they would not be a good choice for use in dim or low light conditions, such as at dusk or for use in a dark shaded forest, or for looking at objects in the night sky.  Because they are waterproof and fogproof, these binoculars would be suitable for use even in wet or humid conditions.  The reasonable price range of the Bushnell H2O 10x25 Waterproof FRP Binoculars makes them a very good choice for a person who is considering an entry level pair of general purpose binoculars that are suitable for almost any type of outdoor use, and they definitely provide a reasonably good value for the cost.  It should however be noted that as I said earlier in my view, that I would prefer a pair of binoculars that have a larger objective lens for outdoor use because of the limitations that a small objective lens has in lower light conditions.  I prefer binoculars that have an objective lens of at least 35 to 42mm and above for general outdoor use.  However, as stated earlier, in well lit situations a pair of compact binoculars with an objective lens of 25mm is adequate for casual viewing. 

            Well I would like to thank you for taking the time to read my review, but now if you will excuse me, I must get back to practicing my guitar.  Good luck, and good viewing.
