Upgradability: a product that never gets old

Telos thermal imaging monoculars are designed for timeless use. As we know, high-tech industries are improving and changing on a yearly, if not monthly, basis. Thermal imaging is no exception. Not to mention, we as human beings often change our habits and minds.

The Telos product line is intended to adapt to the ever-changing needs of a particular hunter. It is the first line of thermal imaging devices on the market offering the option of a technical upgrade.

Become a Telos owner and you will be able to improve and upgrade your device in the future. You will be free to change to more powerful optics, add a higher resolution sensor or display and more efficient and functional electronic parts. You will even be able to equip your device with a laser rangefinder and additional optical channels so it will always be relevant for you and cost effective.

This new unique Pulsar solution is currently in the development phase and will be introduced in 2024. All Telos monoculars purchased in 2023 will be eligible for the upgrade as soon as this service starts.

Extreme thermal sensitivity

For us Telos is synonymous with superior quality and timeless solutions. Let’s take a closer look at this magnificent device, freshly delivered from our manufacturing.

The first to represent the line is the Telos LRF XP50 thermal imaging monocular equipped with the best European made Lynred sensor with a 640x480 resolution and @17 microns pixel pitch.

The real game changer is its extreme NETD thermal sensitivity under 18 milliKelvin. This sensor quality guarantees simply stunning thermal imaging capabilities even in the most severe weather conditions.

Add the fast-aperture F50/1.0 germanium lens, and you have the highest possible quality and most detailed and informative image in any hunting conditions.

The new Telos LRF is ideal for detecting an object from greater distances. Use the built-in precise laser rangefinder for quick and error-free distance determination. The LRF measures distances of up to 1 kilometer in single measurements and continuous scanning modes.

Advanced Pulsar image boost technology

All Telos models will feature in-house developed advanced Pulsar image boost technology. This brings Telos thermal imaging to the highest level of detail, clarity and contrast.

The device is able to depict complex scenes in a wide range of halftones – even low contrast objects such as the sky, grass or water surfaces. Plus, software detailing and sharpening of objects at different distances makes the image highly informative.

Manually increasing the thermal imaging sensor sensitivity improves detection quality when observation conditions worsen. A smoothing filter and a wide range of brightness and contrast settings make prolonged observation more comfortable.

Designed for user needs

In a Telos device, the image can be easily adjusted with one hand. The classic smooth digital zoom and focusing rings are located on the lens in the classic layout, one by one, like professional cameras, which is ideal for both left- and right-handed hunters. The consistent arrangement of the rings enables getting a clear image with the desired magnification quickly and with minimal effort.

The vertical symmetrical layout of the control buttons allows Telos to be used with both hands with the same comfort level – the buttons are located in a row on the top panel. And the attachable hand strap can be moved to the right or left side of the device according to your preferences.

For even more adaptability and comfort of use, the Telos offers customizable controls and a user interface. These new thermal imaging monoculars are characterized by advanced functionality, but determining the priority of a particular function is the privilege of the user who is free to reorder the menu items and determine the button functions.

Ready for the toughest conditions

You will be able to use the new Telos LRF XP50 for observation for more than 8 hours on a single battery charge. The brand new LPS 7i quickly replaceable Li-ion battery doesn’t require special chargers – simply connect it to any network adapter via the USB Type-C port and charge it using the Power Delivery fast charging protocol. Moreover, the LPS 7i battery supports wireless charging.

The Telos thermal imaging monoculars have been designed for tough wilderness conditions. They work properly under an extreme range of temperatures from -25 to +50 °C. The devices are completely waterproof when fully immersed in water.

Moreover, the rubberized body of the Telos is exceptional quality and wear resistant. It is non-slip in humid conditions and holds firmly and very naturally in the hand of the hunter. Plus, the housing is easy to clean and retains its original appearance for a long time.

Taylor-made ergonomic and functional carrying case

The new Telos comes in a stylish, user-friendly and comfortable case. Tailor-made for this device, it is ideal when a hunter is moving a lot and fast and needs to be able to quickly remove or put the device in the case.

The system of attachment belts distributes the weight optimally on the hunter’s body, taking the weight off the shoulders, back and neck and allowing free movement, bending and turning without fear the device will fall out. Additionally, the Telos case is equipped with straps for attachment to a waist belt, as well as a modular Molle attachment system, including backpacks and webbed gears.
