This lightweight, compact Thermal Imaging Scope is small enough to fit in your pocket and with its robust design, you'll be able to take it with you wherever you go and use it in all weathers (rated IP66). Its simple, ergonomic design, along with its easy grip exterior means it is comfortable to use singlehandedly, with all buttons within easy reach, comfortable for both right and left handed users. 

The TD210 is great for tracking, using its 256×192 12µm thermal sensors with a thermal sensitivity of <50mK, which is especially helpful in environments where there are low temperature differentials (e.g. rainy or foggy conditions). It has a 1X-2X digital zoom viewed on a 1280x960 LCOS (liquid crystal on silicon) screen, which offers excellent contrast and response time. Realtime footage can be viewed on your smartphone via WiFi using the dedicated free app, TargetIR, available for Android and iOS devices. This is especially helpful during group viewing or when the device is mounted on a tripod. Please note that the WiFi streaming for Android devices only functions on true Android operating systems 10 and above.

As with the professional Guide Thermal series, the TD210 features a picture in picture mode which adds a small second screen on the image when zooming in on a subject, allowing you to observe the wider field of view at the same time. There are five operating modes available: Black hot, White hot, Red hot, Iron hot and Blue hot, helping to provide crisper images depending on the situation. There are also three Scene Modes, Natural, Highlight and Enhance, allowing for smooth gradation, highlighting the difference between highest and lowest temperatures, and bringing out high temperature subjects respectively. It also comes equipped with a laser rangefinder (up to 200m) so you can point out what you are viewing to those with you without the need to make noise.

This compact device boasts a long battery life of up to 8 hours on a single charge, with an adjustable automatic power off and a 2 second start up time.
