The RS24 is the lowest cost variant in the R-Series. A 240 x 180 core gives detection and targeting capability out to 100 yards. As an entry-level system, the RS24 gives new night hunters the ability to get into the game at an attractive price. It is relatively de-featured compared to the RS32 and RS64, but provides a solid thermal platform for shooters on a budget. FLIR RS24 240x180 Thermal Weapon Scope
