Such units do exist, and some are even equipped with extra features. To find out what to look for when you’re shopping for this particular type of monocular, see our buying guide below.
Range and optics quality
A thermal imaging monocular works by detecting heat, so this is the first thing you should check when you compare various models. A good thermal imaging monocular will offer the possibility to observe and detect heat at large distances. The quality of optics provided should be superior, too, if you want to use the monocular when hunting, and not only.
A variable magnification helps to increase the usability of the monocular, as it allows you to bring objects closer. The color palettes offered should render a clear image and having several to choose from helps, as well.
Video recording capabilities
A built-in video recorder makes an imaging monocular more than just a simple unit. See what resolution is used for the videos you are going to record, and don’t forget to check the Wi-Fi capabilities, too. You should be able to record and transfer your videos to other devices with ease. Some models come with a dedicated app that allows you to stream the videos you’re recording.
Take a look at the internal storage of the unit. That will give you a rough idea about how much video content you can record. Next time you go hunting, don’t forget your essential equipment, such as shooting glasses and your monocular that can document your adventures in the wild.
Resistance to harsh weather conditions
To face inclement weather, hunters and anglers take care of choosing the right clothes, like hunting waders and other waterproof equipment. To make sure that the monocular you are going to use will be capable of remaining undamaged even in harsh climate conditions, pick one that is waterproof.
It also serves to get a model that is dustproof and fog proof. The water resistance capabilities are one thing, but to keep the image clear, you will have to count on a unit that does not let particles of dust in or allow the fog to transform into water droplets on the lenses. Your hunting or fishing adventure should be perfect, so ensure your gutting knife and all the other equipment are kept in waterproof cases, just like your monocular.
