Known issues

While the ATN OTS HD TIMNOH381A offers outstanding performance, you may not be so crazy about how fast the battery drains. According to some users, having an extra pack available should solve this problem, but be aware of it in case you plan to take the monocular with you on trips.

Another issue signaled by a reviewer is the lack of a firmware update for this series on the manufacturer’s page. While this aspect does not have a direct influence on the capabilities of the thermal monocular, given the price, users expect more attention to detail from the maker of this particular model.
