I would recommend the
DNT TNC635R ThermNight Thermal & Night Vision, which is undder $3,000.00
It has a 640x512 thermal core paired with a Sony Starvis 2 powered digital day or night objective lens.
The picture in picture enables the user to identify via thermal and identify with the digital day/night lens.
The thermal magnification range is 1.5 - 6x, while the digital lens has a 5 - 20x magnification range.
The laser rangefinder and ballistic calculator are a nice feature since it can be difficult to judge distance with thermals.
The on-board audio and video recording lets you share your most important hunts and shots.
This optic offers great thermal resolution for detection and ensures precise shot placement and target identification.
