Every user has their own unique needs and circumstances. The best
thermal monocular for you is the one that best suits the range of
applications in which you expect to use your monocular. Here are some
features to keep in mind as you carryout your research.
Because a thermal monocular detects objects by their heat signatures
via its sensor, the resolution of this sensor needs to be of good
quality to produce satisfactory images. Most of the high-resolution
thermal scopes on the market come with a detector that has 480 x 640
pixels. This is the minimum standard that you need to look at in a
thermal scope if you want some sharp high-quality images.
To convert the heat signature into an impression that is easy to
visualize for a human, a thermal monocular must also come with a decent
display resolution as well. Again, a device that comes with 480×640
pixel resolution will work well.
A high refresh rate means that the images produced by a device will
be at a quicker rate and will provide more data about the current
status of the object or scene under observation. Normally, anything over
30 Hz is considered to be sufficient.
Detection range is a very subjective criteria. For certain types of
hunting, super long distances are needed. For general outdoorsmanship,
these long ranges are excessive and unnecessary. Consider your specific
plans before deciding which range suits you.
Out in the field, you never know what the weather will throw at you.
Even the most rugged thermal devices have their limits when it comes to
The best thermal imaging devices can handle both subzero temperatures
as well as high temperatures that exceed 110 degrees Fahrenheit.
It is important to consider the overall durability of your monocular.
Field conditions can be bumpy! Your device will be more delicate and
vulnerable with bigger objective lenses. Most manufacturers make
waterproof and shockproof appliances to make them safe. If you are
looking to move around a lot, consider more rugged options instead of
Thermal monoculars come with various color modes as well. Darker
shades represent the objects that are emitting lesser energy while the
brighter ones are emitting more. Some people find it difficult to see
different colors and for them, there are a range of options. Varied
color modes are useful features, so make sure that the option you go
with has a color palette that doesn’t strain your eyes too much.
As with most gadgets, battery longevity is a major consideration.
Thermal monoculars come with a vast number of integrated features that
run out of battery very quickly. For instance, Wi-fi and Bluetooth
connectivity eat up the battery extremely fast. Therefore, if you are
going to use these features, go for a battery that can reach at least 10
hours of backup time.
Thermal imaging technology is constantly evolving. As the technology
develops, more and more manufacturers are introducing new features that
weren’t there in the past but are now considered to be must-haves. Here
is a list of some the features that the best monocular would have.
A rangefinder is a convenient feature that has become a popular
addition to many recent models of thermal monoculars. With a
rangefinder, you can measure the distance between you and the target.
Including a rangefinder with a thermal monocular is especially useful
for hunters who have one less optical tool to lug around.
WiFi and Bluetooth features are helpful for users who intend to
capture photographs and videos through their thermal monocular. With
these features, you can directly share the files or can store them on
the cloud to access later. This is a must-have feature for researchers
or people who are gathering data on their fieldwork.
A compass speaks for itself. Outdoorsmen should always carry a
compass, so having one built in saves space and lightens the load.
Most thermal monoculars have some amount of magnification available.
At long ranges, a high zoom is a great way to get that extra bit of
detail. Some tools even come with variable zoom capabilities!
