Guide TD433 Thermal Monocular

The Guide TD433 brings 400 × 300 12 μm thermal at 25 mK NETD with a class-leading 12-hour battery life into the sub-$1,500 monocular tier. At $1,449 it sits in the same price range as the Pulsar Axion 2 XG30 (~$1,500) and ATN OTS LT 320, but with a finer pixel pitch than 17 μm 384-class entry monoculars and replaceable 18650 batteries instead of proprietary cells.
