MRKJ thermal imaging is even listed in the top ten best thermal imagers in the world
*Thermal sensor resolution - the higher the resolution, the clearer the image, but the higher the cost.
*Refresh rate (in Hz) - how many frames are generated per second; the higher the refresh rate, the higher the cost
*Optics - high quality optical elements can produce better images, but also increase the cost.
*Magnification - the higher the magnification, the farther you can find / kill, but the higher the cost, the narrower the field of vision.
*Quality - higher quality / waterproof materials ensure that your monocular or range will last longer, but will increase costs.
The thermal imaging sight is designed to help hunters get better shooting targets from further places. Entry level thermal imaging sight for 100 to 250 meters; The very expensive thermal imaging sight can help you accurately locate objects 1000 meters away. The use of better lenses (usually germanium lenses) and more complex optics in the thermal imaging sight allows higher magnification, which is another reason for their higher cost. The thermal imaging sight also has more electronic and software functions to assist the shooter, such as trajectory calculator, rangefinder and automatic activation video recorder
You may also want to know the difference between 5x50 thermal imaging and 3x15 thermal imaging? The first number refers to the magnification of the image, so 3x will enlarge the image 3x. The second number (15) refers to the size of the front lens (target size), in millimeters
Your initial idea was that you should always choose the maximum magnification and objective size, but this is not the case. First, the larger the magnification and the size of the objective lens, the more expensive your telescope or monocular telescope will be; Secondly, the larger the magnification, the more difficult it is to stabilize the telescope or target monocular without a tripod. Finally, the higher the magnification, the smaller the field of view. What is vision? The field of view is how many images can be seen when viewing the range. For example, the field of view is 30 meters. At 1000 meters, when you observe through the thermal imager without moving the lens, you will be able to see an image of 30 meters. So what does all this mean? This means that you should consider the situation and distance you may use the thermal imager and buy it accordingly. If you won't be found or shot more than 300 meters, you may not need to buy a thermal imager with powerful optics and higher sensor resolution; You can not only save a lot of money, but also make it easier to use.
