We Offer a Huge Selection of Outdoor and Hunting Thermal Tech

Through the use of thermal imaging scopes, hunters can detect heat signatures of feral hogs, even through foliage or light fog, making it much easier to pinpoint their location. This technology not only increases the success rate for hunters but also plays a significant role in controlling the population of invasive feral hogs, which can cause extensive damage to crops and natural habitats.

Thermal Imaging Scopes

We provide an assortment of sophisticated thermal clip-on scopes designed to augment and optimize the experience of hog hunting by offering superior target acquisition and clarity.

Handheld Thermal Scopes

In addition, our inventory encompasses an extensive selection of handheld thermal scopes, meticulously engineered for exceptional performance and convenience in various observational settings.

Types of Thermal FLIR Imaging Devices

The SPI Dauber T336-50-C is a military-grade hunting weapon with advanced thermal vision imaging.

Un-cooled Thermal Clip-Ons

Uncooled thermal scopes are among the most prevalent types of thermal imaging devices

Clip-on thermal scopes are designed to work in conjunction with a standard day scope. They can be quickly attached or removed without the need to adjust the zero of your day scope, offering flexibility and convenience in rapidly changing conditions.

This clip-on scope operates with a FLIR Tau 2 17µm uncooled microbolometer, offering a resolution of 336 x 256.

Standalone Thermal Rifle and Sniper Scopes

Military Grade Thermal Rifle Scopes

Uncooled standalone thermal rifle scopes are designed to replace the conventional day scope on your weapon. They operate at room temperature and don’t require a cooling system, making them lighter and more compact. This reduces the overall weight of the firearm and makes it more maneuverable.

This clip-on scope operates with a FLIR Tau 2 17µm uncooled microbolometer, offering a resolution of 336 x 256.

SPI Weapon Sights: Technologies and Features

SPI thermal rifle scopes and sights use the latest technology in infrared imaging to reveal even slight temperature fluctuations and variations that occur in both man-made and natural objects. They use that information to generate an image even in near to total darkness. With multi-coated, Germanium lenses and compact, sturdy housing, our sights are water, dust, and sand-proof for unmatched reliability in uncharted territories, rough terrain, and extreme weather conditions. Our thermal weapon sights also offer:

  • A fully adjustable electronic fine reticle for precision shooting
  • Professional-grade lens materials and ergonomic design
  • A digitally controlled boresight, which allows to change the position of your reticle without losing sight of the running center coordinates
  • A locking quick-release mount
  • Wireless remote control
  • Option to use either CR123A Lithium batteries or additional battery packs

Our thermal weapon sights are developed using the science of black body radiation, which demonstrates that objects with a temperature above absolute zero must emit infrared radiation. Radiation levels increase or decrease in response to changes or variations in an object’s temperature; thermal photography, or thermography, works by detecting the level of radiation that an object emits and translating it into an image. A thermal weapon sight, otherwise called a thermographic weapon sight or thermal imagery scope, combines a thermographic camera and an aiming reticle in one device that can be mounted on a variety of weapons. SPI’s superior thermal weapon sights are made from high-grade construction materials that are lightweight, weather-resistant, and tough.
