Thermal is expensive, so even a 15% discount saves real money. Prime Big Deal Days (Oct. 6–7, 2026) has markdowns across AGM’s thermal lineup and on Topdon’s budget monoculars.
Every year we test thermal optics at night while hunting hogs and coyotes, and shooting targets at known distances. Where we’ve tested a unit we’ll link to its review.
