Ok, the unit I have is a 1.5x 640x480. Rifle I mount it on, ar15, 16" krieger 7.7 twist, known tack driver with 75 grain Hornady tap.
First I read the quick start guide. It's simple enough.
Before I mounted it on the rifle, I compared it against a flir patrol m24 and a l3 mtm as a handheld. Excluding size and weight, it smoked them.
The unit has 7 menus. 1, polarity. 2. Digital focus. 3. Wind/elevation adjust. 4. Reticle color and type. 5. Calibration. 6. Color modes, and 7. Picture capture.
The unit has 4 knobs, no buttons. Knob 1, off on. 2.left side, Menu selection. 3, top knob, polarity, digital focus, and other menu specific functions as you go through the 7 menus. Knob 4, right side, mainly the zoom function when shooting, but a set of functions for each menu. It's the quickest setup I've used yet. Faster than push buttons and joy sticks....
So, I mount it, LaRue lock mount, click snap, done. Turn it on, up in 6 seconds and factory settings, ready to zero.
I look down range, steel and paper with shoot-n-c on white paper. Steel gives clear silhouette I can shoot center mass on. Shoot-n-c absorbs heat and gives thermal signature. 6 rounds later, it's zeroed. Shoot from 25 to 200, both center mass steel hold and thermal signature hold. Hit, hit, hit...
Gb Maryland, didn't notice poi change when zooming. Elevation stayed constant. Had some 1-2 minute wind shift a couple of times, blamed that on me. 4 and 8 x pixellate pretty bad, won't use them on animals.
Tonight we test on live snimals, will report more later..
