Lagging / poor battery life - Covert Optics ThermX HS1 Handheld Thermal Scanner

Initially excited about the ability to throw a 30mm ring on the tube and have a backup if needed. Quickly realized the limited use of this optic, at higher brightness levels the battery life plummets to minutes. The interface is extremely lagging compared to comparable scanners in the Flir or AGM lines in terms of price. Spend your money on another scanner.
