The Guide TS435 is a thermal imaging riflescope for demanding shooters who want to shoot with extreme precision over medium distances. The thermal riflescope has a 2x to 9x magnification and can pick up heat sources up to 950m. The 50hz refresh rate makes it easy to track fast moving objects. The state-of-the-art detector in combination with an OLED display results in razor-sharp images. The TS435 comes with a separate Picatinny/Weaver mounting.

Optics and display
The thermal riflescope is equipped with a 400x300@17μ 'TEC metal encapsulated' infrared detector. The environment is displayed on an amazing 1024x768 OLED display. The 50hz refresh rate provides real-time images. The TS435 features a 35mm lens with a 2x optical magnification. You can enlarge it up to 9x by using the digital zoom (Picture-in-Picture also available). You can focus on the surroundings as you like using the focus ring.

Focusing and zero setting
In order to follow targets easily and shoot with extreme precision, you can use 10 different crosshairs (see images on the right). You can set the colour of the reticle in black or white. The reticle can also be switched off. The 'zero' can easily be set and saved from the main menu. In total you can save 6 different zero settings.

Observation modes
You can select seven thermal colour pallets: White Hot, Black Hot, Red Hot 1/2/3, Green Hot and Blue Hot. Additionally, the Hot Track function allows you to "mark" the hottest object on the screen with an indicator. This makes finding and tracking targets easier than ever. You can also adjust the contrast of the environment to your own preference.

Stadiametric rangefinder
The rifle scope is equipped with a stadiametric rangefinder, which allows you to calculate the distance to an animal of known size (e.g. hare, boar or deer). This function can be used for objects with a size of 1.8m / 0.5m / 0.25m.

Reliability properties
The thermal rifle scope is resistant to recoil of 500G/1ms. The TS435 is also IP67 certified (water and dustproof and therefore suitable for all types of weather). You can power the device with one 18650 battery, which you can quickly and easily insert into the device. This allows you to use the rifle scope for up to 5 hours. A rechargeable 18650 battery and charger are included as standard.

Application Guide TS435
This thermal riflescope is ideal for hunting, shooting or airsoft. The Guide TS435 is mainly used by demanding users who want to shoot at medium distances. With the help of a video cable (included) you can display the images in real-time on a monitor. At the optional accessories you will find some waterproof, fully-certified transport cases and weapon cases.

These thermal imaging scopes by Quantum are based on an IR sensor. The scopes are designed for use in both nighttime and in the daytime during low visibility conditions (fog, smog, rain etc). You will also be able to see through obstacles that are partially hindering targets (branches, grass, thick bushes etc).
Unlike image intensifier based night vision devices thermal imaging scopes do not need an external source of light and are not affected by bright lights.

FEATURES:
Color palettes
Quantum XD/XQ offers a choice of 7 color palettes for captured by objective lens image, monochrome (usual “hot white”, “hot black”) and color highlighting the hottest and coldest areas with different colors.
Rangefinding reticle
Quantum XD/XQ has a stadiametric rangefinder performed in the shape of rangefinding reticle which enables distance measuring to observed objects with known height (deer - 1,7m; boar – 0,7m; hare – 0,3m) with a sufficient precision.
High image frequency
Due to the high image frequency (50 Hz) it is comfortable to use thermal camera dynamically (during rapid moving of observer or object of observation).
Operating modes
The Quantum XD/XQ suggests three operating modes, each designed to deliver best possible image in specific viewing conditions. The modes are as follows: “City” (enhanced contrast), “Forest” (low contrast) and “Identification” (improved rendering of hot objects’ details).
Quick start-up time
The Quantum XQ thermal scopes feature short start-up time (2 seconds) from the push of a button to full operational status. This is one of the best results in its class.
Display OFF
When it is necessary to temporarily stop observation the user can apply DISPLAY OFF function. It provides the necessary level of camouflage (no light from the eyepiece of the device) between observation sessions as well as the fast restart of observation (when display is turned off, all other systems are working; for normal operation it is enough just to power on the display again).
