Image Quality
One of the most important factors to consider when choosing a Thermal Monocular is image quality. The higher the resolution and refresh rate, the clearer and more detailed the images will be.
Look for monoculars with at least 320×240 resolution and a refresh rate of at least 50Hz. If you’re buying from us, you can find all this information on the individual product page. Most of what you need is listed under the “Additional information” tab.

Durability
If you plan on using your Thermal Monocular in harsh environments, it’s important to choose one that is durable and resistant to water and dust. Look for monoculars with a high IP rating (such as IP67) and a rugged design to ensure they can withstand rough conditions.
Again, this information can be found under the “Additional information” tab.
Field Of View
The field of view is the area that you can see through the monocular at a given distance. A wider field of view allows you to see more of your surroundings, while a narrower field of view allows for more detailed images of specific objects.
Additional Features (multiple colour modes, adjustable zoom etc.)
Different Thermal Monoculars come with a variety of features such as multiple colour modes, adjustable zoom, and image enhancement algorithms. Consider which features are important to you and choose a monocular that meets your needs.
For example, if you plan on using the monocular in a variety of lighting conditions, a monocular with multiple colour modes may be useful. Or if you need to zoom in on distant objects, an adjustable zoom feature may be important.

Price
Thermal Monoculars can range in price from budget-friendly options to more expensive, high-end models. Determine your budget and look for a monocular that fits within it while still offering good image quality and durability.
Keep in mind that more expensive monoculars may offer better image quality and more features, but they may not always be necessary (depending on your needs).
Range
Consider the range of the monocular and whether it meets your needs. Some monoculars have a longer range than others, allowing you to see objects from farther away.
If you need a monocular for long-distance viewing, make sure to choose one with a good range.
