Looking at core thermal performance, the FLIR TS24 has a clear edge. Its 240x180 VOx microbolometer sensor captures noticeably more detail than the ATN's 160x120 array. That means you can resolve facial features, animal markings, and terrain elements at greater distances. In my testing, small heat signatures remained identifiable 20-30% further out with the TS24.

The FLIR also boasts a much wider 24° field of view compared to the ATN's narrow 6.5°. This allows you to scan larger areas faster without panning. Combined with the crisper sensor, the TS24 is simply better at quickly locating and classifying thermal targets, especially at close to mid-range.

However, the ATN claws back some advantages in the optics department. With a 25mm objective lens and 2.5-10x zoom, it can reach out further to spot distant subjects. The digital zoom is smooth and maintains decent quality up to about 6x. The FLIR is fixed 1x magnification only - great for situational awareness but limited for long-range details.

The ATN also has a faster 50Hz refresh rate that provides a smoother, more natural image than the FLIR's 9Hz. There's less choppiness when panning and tracking moving targets. But the FLIR's Proprietary Digital Detail Enhancement does a commendable job cleaning up noise and stutters.

Both monoculars offer multiple color palettes to optimize the image for different environments. I found the FLIR's "Instalert" and ATN's "Graded Fire" modes particularly useful for picking out heat signatures in busy urban areas. But the FLIR's higher native resolution gave it the overall fidelity advantage across palettes.

Another big differentiator is recording capability. The ATN OTS XLT 160 can capture photos and videos directly to its 8GB of internal storage, no phone or card required. It's incredibly convenient for gathering evidence or studying targets later. The FLIR Scout TS24 has no onboard recording - only real-time viewing through the eyepiece or analog video out.

The ATN extends its tech lead with a higher resolution 720p color display versus the FLIR's basic VGA. Menus are crisper and more detailed, and the image stays cleaner when zoomed in. Both have manual brightness adjustment to balance visibility and light discipline.

Ergonomically, the FLIR Scout TS24 and ATN OTS XLT 160 are quite similar. Both feature a rubberized non-slip housing, well-placed controls, and a comfortable eyecup. The FLIR's sideways-oriented hand strap is a bit more stable for me than the ATN's vertical design. But the ATN's lighter 0.81lb weight (vs 1.59lbs) is less fatiguing for extended handheld use.

The FLIR also feels slightly better sealed against the elements with an IP67 waterproof rating (submersible to 3ft for 30min). The ATN has no official ingress rating but does feature a turret-style lens housing that's fairly resistant to rain and splashes.

Finally, the ATN boasts superior battery life at 10+ hours from its internal lithium pack. I easily got a full day of heavy scouting on a charge. The FLIR is BYOB (bring your own batteries) with 4 AAs providing about 5 hours of juice. Extras are light and cheap but you'll need to manage a stash on longer trips.

ATN OTS XLT 160 vs FLIR Scout TS24: Design

The FLIR Scout TS24 and ATN OTS XLT 160 are both designed for field use, with features optimized for durability, ease of use, and portability.

FLIR Scout TS24 Design

ATN OTS XLT 160 Design

The FLIR Scout TS24 and ATN OTS XLT 160 share similar handheld form factors optimized for field use. Both feature rugged polymer housings with molded rubber armor for drop protection and grip.

Control layout is simple and effective on both units. The FLIR places buttons for power, palette selection, polarity, brightness, and zoom along the top ridge for easy one-handed access. The ATN shifts these to the sides but keeps them well-differentiated and operable with gloves.

I do prefer the FLIR's sideways-oriented hand strap for better stability when glassing. The ATN's vertical strap is quicker to slide in and out of but allows more wiggle and sway. Your mileage may vary.

The FLIR Scout TS24 is a bit bulkier overall at 9.36" x 3.33" x 2.62" and 1.59lbs. The ATN OTS XLT 160 shaves a few inches and about half the weight at 6.9" x 2.6" x 2.1" and 0.81lbs. Neither will burden your pack but the ATN disappears in a large pocket for faster deployment.

Eyepiece design is comparable, with a sculpted rubber eyecup and diopter adjustment. The FLIR's larger 40mm ocular lens provides a slightly broader viewing window but the ATN's OLED is crisper with better contrast. Focus is fast and forgiving on both.

Rounding out the design, the FLIR Scout TS24 is defensively constructed with an IP67 waterproof and dust tight rating thanks to its internal focus and enclosed ports. The ATN OTS XLT 160 lacks an official IP rating but does feature O-ring seals and a turret-style lens assembly to resist moderate moisture and splashes. I don't recommend submerging either but the FLIR has a clear ruggedness edge.

FLIR Scout TS24 or ATN OTS XLT 160: Owner Insights

Let's see what actual buyers have to say about their experiences with the FLIR Scout TS24 and ATN OTS XLT 160:

FLIR Scout TS24 Owner Reviews:

Praises: "The image quality and detection range on this thing is unreal, especially for the size. I can easily pick out coyotes, hogs, and deer at 3-4x the distance of my old scope."

"Rugged as hell and totally waterproof. I've banged it around on rocks, dropped it in a creek, and used it for hours in pouring rain with zero issues. Built like a tank."

***

Drawbacks: "I really wish it had some kind of recording functionality. Even just a couple snapshots or a short video clip would be a huge benefit for tracking and surveying."

"The fixed magnification is a bit limiting for long-range spotting. An optical zoom would make it much more versatile in open country. But I knew that going in."

ATN OTS XLT 160 Owner Reviews:

Praises: "The 10x zoom is a game-changer. I can glass miles of terrain and positively identify targets that would just be blobs on my old 1-4x thermal. It's like having binoculars and a thermal in one."

"Amazing battery life and the recording is super useful. I'll scout for 8-10 hours and still have juice left. Love being able to snap pics of pigs for planning stand locations too."

***

Drawbacks: "The 160x120 sensor is a little grainy compared to higher-end thermals. You can definitely tell it's not as sharp as a 320x256 or 640x480. But for the price it's totally acceptable."

"No weatherproof rating is kind of a bummer for a hunting optic. I've used it in light rain but I'm always paranoid about really soaking it. A fully sealed housing would give more peace of mind."

Overall, owners of both the FLIR Scout TS24 and ATN OTS XLT 160 are very satisfied with the thermal imaging performance and build quality for the price. TS24 users frequently praise the crystal-clear image, ruggedness, and simple operation. The main wishes are for video recording and zoom.
