Thermal rifle scopes can cost thousands of dollars, have many different features, and depending on specification, can offer quite different performance.

So, how do you choose the best thermal scope? First, you need to know what you’re looking for, and to determine that, you should ask some of the following questions.

• What’s the sensor resolution? Sensor resolution is one of the primary determinants of quality in a thermal scope, as it impacts the resolution of the sight picture on the display. The higher the resolution, the clearer the sight picture will be if you hold all else equal. A lower pixel pitch is also desired here as well.
• What’s the NETD rating? NETD, or noise equivalent temperature difference, rating indicates how sensitive a thermal scope is to temperature differentials. The lower the NETD rating, the more sensitive the scope is, and the clearer the sight picture will be. You want a high sensor resolution and a low NETD rating. 
• What sort of advanced image processing does it use? Some thermal scopes, such as some Nocpix thermal scopes, use advanced image processing algorithms such as Reality+, an AI-powered algorithm that helps eliminate visual noise to deliver a clearer, sharper sight picture. 
• Does it have any advanced features, like an integrated LRF? Some thermal scopes are equipped with an integrated laser rangefinder that can estimate ranges accurately within a second. 
• Does it support more than one color palette to preserve my night vision? Some thermal scopes support more than one color palette, like crimson, which will help preserve your night vision during long night hunts. 
• How much does it cost? For better or worse, budget is a factor here, and you need to make sure the scope you’re considering falls within your budget range. 
• What’s the battery life like? Some thermal scopes offer better battery life than others, especially under adverse conditions. Some are also powered by dual power supplies such as built-in and removable batteries. Others enable hot swap capabilities for uninterrupted power.
• What’s the weight? Some thermal scopes are very light and others are very heavy. This can impact your loadout. 
• What’s the form factor like? Many thermal scopes mimic the controls of optical scopes, but others have more unique form factors. 
• What’s the IP rating? The higher the IP rating of a given thermal scope, the better it will be able to withstand adverse conditions when exposed to the elements.
• What’s the operating temperature range? Electronics are not as effective in extreme cold, so it’s important to be aware of what the operating temperature range is. Some thermal scopes still function at temperatures below zero. 
• What sorts of mounts does it support or flexibility does it offer? Some thermal scopes can be helmet mounted, others simply support Pic rails. Some can also be used as clip-on thermal optics which means they can be used to convert your existing optic to a thermal scope without needing to replace the optic or re-zero it.
