Compact thermo imager - Leupold LTO Tracker Thermal Imaging Monocular

This is quite unlike my first thermo imager which uses a smart phone display for its image view screen. Both will display objects of different temperatures. The LPO had fewer color palates and the field of view was smaller. This was in its favor so it consumed less battery and had a much larger battery for a longer in field in use duration likely several nights where my first thermal imager would last about an hour. Also the image viewer is much less likely to be seen by your prey. The small shape has its center diameter eyeballed just less than 30MM and may be clamped in like an Aimpiont if you needed its field of view clamped offset to direct your scope to it. It must have been designed by a hunter/tracker.
