The TigIR-6Z+™ is currently the lightest and shortest Clip-on Thermal with 55mm optics. No other device with such a short overall length of only 111mm achieves a range of 3000m (standing person). These small dimensions could only be achieved by developing a specially folded ocular optic. This makes it possible to use the device in front of different scopes (3-6x) etc. without loss of quality. Since the entire housing is made of highly robust aluminium and the objective lens is athermal, the TigIR-6Z+™ has outstanding precision even under extreme temperature conditions. The housing surface is hard anodized and coated with Cerakote. The TigIR-6Z+™ can resist even hard impacts in a rough environment, but is not much heavier than 500g/17,6oz and therefore lighter than any other comparable device. The TigIR-3Z™ is an affordable entry-level-version, which has a smaller viewing angle but the same high coverage range of 3km.
