How to Choose The Best Borescope

When choosing the right borescope for you, you have to take into consideration that there are so many different kinds to choose from. They are used for a wide variety of jobs so they are all different. It is important that you carefully study the different models available so you can best determine which one will suit your needs. One of the most important things to consider when purchasing a borescope is whether you will need a rigid or flexible model. As a rule, the rigid borescopes offer the best image quality, are easier to use, and are even less costly than the flexible models. So your decision is already made for you, right? Well it’s not that simple. You see, flexible models can allow you to see inside of places that a rigid model simply cannot. So your decision is largely based on what you need the instruments for. However, if you know that rigidity is not an issue for you, then select this type of borescope. Another thing that will influence your decision when it comes to picking out the right borescope for you is the diameter. It is crucially important that the instrument you purchase actually be able to fit into the hole required. It may be in your best interest to purchase one that is slightly smaller than needed so you have a little room to move about. This also presents a problem because the better the borescope fits the hole, the better your image will be. Of course if you will be using this instrument for several purposes, you may want to simply buy borescopes that will fit each of them.The length of your borescope is also important, you will want one that is long enough to go deep inside of the object you are examining, but one that is too long may just go right through. Just be sure to do some measuring or estimates first and you will be fine in this area. Pay attention to your borescope’s field of view as well; these may range between wide, medium, and narrow. This is another area where this is bit of a trade-off as the wider your field of vision is, the less magnification is possible, while a thinner field of visions produces a more magnified image. A moderate lens is probably best for most jobs, but for looking into confined spaces a wide angle is best and a narrow angle is best when you want to see a specific area in great detail. Finally there is the issue of illumination because you will need some light if you are going to be looking into dark crevices. While inexpensive Borescope models may simply use a bulb at the tip for light, these days fiber optics is used in most models.
