The sight is equipped with a highly sensitive passive receiver of a far infrared band (LWIR) with resolution and sensitivity within 20-30 mK. Several lens modifications (50 mm, 75 mm and 100 mm) allow for choosing a sight model that best meets the objective. All models have a manual focus for the comfortable and effective usage of the device.

A built-in colour high-resolution microdisplay and an eyepiece with diopter adjustment provide a high-quality image of aiming reticles and a minimal movement step during adjustment fire. Aiming reticles are implemented in automatic reverse functions for saving reticles’ contrast and automatic scaling depending on the enlargement range. Reticle coordinates can be adjusted both in clicks and in centimetres. A ballistic calculator allows compensating changes in atmospheric conditions, the temperature of dust powder and windage. The device is equipped with sensors of ambient light and proximity, and angle of sight. Archer thermal imaging sight TSA-9 has a serial interface for programming and remote control, an option for downloading and editing target reticles, ballistics table for every type of programmed weapon.
A built-in recording module allows to take photos and shoot video in several modes. The data is read via a wired (USB) interface. The device has a sealed multi-purpose connector for power charging, video output and control.

The design comes in a shockproof, waterproof plastic housing with pumped inert gas resistant to corrosive environment. Сonveniently arranged controls are protected from accidental use. Two quick detach battery cassettes and a rechargeable battery allow you to change power supply blindly.
