The best thermal scope is the scope that has the features and functions to do what you want and need it to do. For those of you in the market for your first thermal optic, here are just a couple of things to evaluate before buying.

Sensor Resolution

One of the primary determinants of the quality of a thermal scope’s sight picture is the sensor resolution. Holding all else equal, the higher the resolution, the sharper the image will be.

Pixel Pitch

Pixel pitch, measured in μm, indicates the distance between the center of pixels. The smaller the pixels, the sharper the resolution the sight picture will be.

NETD Rating

NETD rating, measured in mK, indicates how sensitive a thermal sensor is to differences in thermal gradients. A lower NETD rating indicates a more sensitive scope and therefore a sharper sight picture.

Frame Rate

Frame rate, measured in Hz, indicates how quickly (or how many times per second) the display image refreshes. The higher the frame rate, the less lag you will experience, enabling smoother tracking and more accurate shots, particularly on targets you have to lead.

Display Resolution and Color Palettes

The higher the display resolution, the sharper the sight picture will be. Many of the best thermal scopes also support multiple color palettes, some of which are suitable for low-light viewing, such as viridian and crimson.

Detection Range

Some of the best thermal scopes in the industry offer a detection range in the area of a mile, for effective scouting, scanning, tracking, and even executing accurate shots on targets at long distances.

Digital and Optical Zoom

Many thermal scopes support both digital and optical zoom. While convenient and often more powerful than the optical zoom supported, digital zoom can result in pixelation and loss of sight picture quality, which does not occur with optical zoom, where it is supported.

Size and Weight

While thermal scopes tend to be heavier than their conventional counterparts, many of them capture the same basic footprint as standard optical scopes. Get one that works for your rifle, application, and loadout.

Form Factor and Controls

Many thermal scopes are designed to replicate the same basic controls for windage and elevation as conventional scopes. Make sure any scope you get has a form factor and ergonomics, as well as controls, that are intuitive or easy to learn to use. Most scopes have only a few basic buttons or controls for all functions.

Power Options and Battery Life

Some thermal scopes have both removable and internal rechargeable batteries, and some of them can be hot-swapped in the field, providing for an indefinite, uninterrupted power supply.

IP Rating

Also, make sure you get a scope with an IP rating that is appropriate for your applications. Many are fully sealed off to moisture and dust ingress, some so much that they can even survive submersion for short periods of time.
