Night Owl iGen NV 20/20
The view from this scope was easily superior to the Equinox’s, an expectation fostered by the added price. We spotted raccoons along the dark shoreline and even noticed the wake of a snake swimming across the river’s surface. It had the highest display resolution, and that made the images highly detailed.

Wins: We could spot a string of three buoys, the farthest at 100 yards using IR enhancement. For spotting markers and obstacles in marine environments, it provided good detail and resolution. It spotted more buoys when the lighted tower was behind the targets. Battery life using inexpensive AAs is a bonus. Its ability to overlay multiple images at a rate of 2 to 30 feet per second further enhanced the apparent light amplification. It also provided greater image detail than thermal sensing, giving us facial details much like a monochrome image rather than a silhouette.

Losses: It had a shorter range than FLIR and less contrast for spotting warm human targets than did FLIR. With the darkest background it didn’t capture as many buoys.

Final Word: This makes an excellent navigation tool with some ambient light but doesn’t paint human targets with as much contrast as thermal imaging does, reducing its SAR value.
