High resolution, low image quality. - ATN ODIN LT 640, 3-12x35mm Compact Thermal Viewer Sensor, Multiple Patterns & Color Options Reticle

The first unit I received was defective. It had a part rattling around inside and would only power up properly 1 in 3 tries. The replacement unit appears to operate properly, however the image equality is poor. While you can see the higer resoultion of the sensor in the greater detail of objects in the center of your field of view, the sensor sensitivity appears to fade as it gets near the edge of the screen. I have tried every combination of Contrast, Sensitivity, and Brightness settings and the problem persisits. You have a high-contrast oval in the center of the image and it fades to a dull low-contrast image at the edges. This adds to the tunnel vision that you get from the already narrow field of view.

When using the Auto NUC function on either of the increased levels of magnification, it NUCs about every 3 seconds, very annoying.

Battery life when using brand-new name-brand (Surfire) rechargeable lithium batteries in cold temps (you know, the temps in which I hunt) was less than 1 hour. That's half of what they say you should get with the single battery option. So my choice is spend the the extra $90 for the rechargeable double battery pack and hope it more than doubles the battery life, or feed this thing $20 of batterys every night that I hunt.

I am returning this and will contintue to hunt with my 320 resolution ATN OTS LT, which costs half as much and works as advertised.
