A good thermal monocular is not that hard to find once you have done your research. Finding the time to sift through all the options available for sale can be hard, but this why we have taken the time to compile the buying guide below for you. We have all the information you need to help narrow down your options and make it easier to find the perfect product for you.

Quality of the thermal sensor

Without a high-quality thermal sensor, the experience that you will be getting from your purchase could be unsatisfying, and this is why you need to be careful when you decide on your product. Be sure that your device can not only identify properly objects that are close to your position, but also more distant targets.

A device that you can use to observe far away objects can be extremely useful when hunting, and even when doing some surveillance. If this feature is important for you, make sure that your option is equipped with some magnification lenses or at least some zoom capabilities.

Then there’s the quality of the thermal sensor that you need to consider carefully. Even the best night vision monocular won’t be able to give you the clarity that a good thermal sensor can give. An accurate thermal sensor will be able to help you discern warm objects such as an animal or other people from great distances.

This is what makes a thermal monocular quite an attractive choice when it comes to hunting and surveillance. Warm bodies will be easily distinguishable even in complete darkness. A good sensor will make them stand out so that you are always aware of your surroundings.


Build quality

When spending money on a product, you expect it to last, especially when you have to carry it around with you. Looking for products that you only use in your home is easy, but when it comes to products that can be used in the outdoors, you expect the manufacturer to have durability in mind when designing their device.

You need to analyze the device carefully so that you don’t get one that can easily break. Finding a durable product is easy, you just have to look at their body. A cheap and easily-breakable body is easy to spot, whereas a sturdy device will immediately stand out. Most manufacturers will also advertise if their product is shock resistant.

An easy grip is also the hallmark of a quality design. It will not only make it easier for you to hold the device without your hands getting tired, but it will make it harder for the device to slip out of your handgrip. An ergonomic design will not only give you more comfort but also protect your purchase.


Connectivity and display

With most of the options on the market offering recording capabilities, you need to make sure that you can also easily store and transfer your files. Most file transfers are made with the help of a USB cable, but some alternative can offer you the option of recording and streaming video wirelessly.

This means that you will be able to use your thermal monocular as a thermal surveillance camera. The videos will be streamed seamlessly to your computer or phone. This feature can add usefulness to your purchase, making it you able to make use of it even when you’re not hunting or exploring.
