The Sentinel reticle has a brightness control option and a range-finding scale to facilitate adjustment when shooting at different distances (15, 25, 50 and 100 m) provided the shooter knows the size of the target. The reticle colour can be switched at any time from green-on-green to red-on-green.
The optical system employs an internal focusing mechanism. The riflescope can be focused rotating the objective focus ring knob located on the body of the device. 'Definite' click-stop focus position is on 100 m - the focus ring knob becomes tighter as it reaches the mark. To focus the riflescope on close range distances the focus ring knob should be rotated counterclockwise, on long ranges – clockwise.
The stabilized, noiseless power supply eliminates reticle shift and brightness drop, even when the batteries are nearly exhausted. The batteries are positioned vertically which maximizes the reliability under recoil.
The 3 button remote control (two duplicate the "On/Off" function) is helpful for tactical applications and can be mounted on any easy to reach part of the weapon. The third button is intended for an Instant On start-up of the riflescope. This is very convenient when constant observation is not conducted in order to find the appropriate position, take aim and shoot.
Protective lens cap is permanently attached to the body to prevent it being lost and can be slid back down the body when observing or shooting.
The Sentinel riflescope features lightweight and high durability due to its construction of titanium and plastic composite. The device can be operated in precipitation of high intensity.
The riflescope has an extra 7/8” Weaver rail placed on the left side of the body and is designed for mounting accessories (IR illuminator, directional microphone and laser pointer).
The Sentinel riflescopes are supplied with various rifle mounts, including Weaver rail (to install the riflescope on hunting rifles equipped with Weaver or Picatinny rail), Prism 14/200 (a universal base for different mounts including EAW (Apel), Blaser, MAK, and others), Los (to mount carabines «Los 7-1», «Los 4», «Bars 4-1» etc.), AK Side rifle mount (allows the riflescope to be mounted on weapons made in Russia and USSR equipped with Dovetail rail, including carabines “Saiga”, “Tigr”, “Vepr”, “SKS”).
