For Pixfra Mile 3 vs Mile 2, choose Mile 2 PFI-M625 if an 800 × 600 OLED display and 16 GB storage meet your needs, or Mile 3 PFI-M625 if you want a 1920 × 1080 OLED display, 64 GB storage and a lower published NETD. Choose our Arc LRF PFI-A435P LRF or Arc LRF PFI-A635P LRF when you want a 35 mm lens with laser ranging.

Mile 3 vs Mile 2 vs Arc LRF

Our 640×512, 25 mm models differ in published NETD at f/1.0: Mile 2 PFI-M625 is ≤25 mK, Mile 3 PFI-M625 ≤15 mK, and Arc LRF PFI-A625P LRF ≤20 mK. At 100 m, field of view is 30.6×24.4 m for Mile 3 PFI-M625 versus 30.7×24.6 m for Mile 2 PFI-M625 and Arc LRF PFI-A625P LRF.

The seven models below all have 25 mm lenses and manual focus.

NETD ratings alone do not establish overall image quality. Detector resolution, display specifications and NETD describe different parts of the viewing system.

Mile 3 and Arc LRF weights exclude the battery. The listed Mile 2 weights do not specify whether a battery is included, so they cannot establish a direct carry-weight ranking against the other series.

For ranging, Mile 3 PFI-M625 LRF, Arc LRF PFI-A425P LRF and Arc LRF PFI-A625P LRF each have a 1,000 m (3,280.84 ft) laser-ranging specification.

Mile 3: Strengths, Limits and Uses

• Strengths. Our Mile 3 thermal monoculars include a closely matched pair for buyers considering laser ranging. Mile 3 PFI-M625 and Mile 3 PFI-M625 LRF both have 640 × 512 detectors, 25 mm lenses and a 30.6 × 24.4 m field of view at 100 m. Both also have a 1920 × 1080, 0.49-inch OLED display and 64 GB of storage. Choosing Mile 3 PFI-M625 LRF adds laser ranging while retaining those specifications.
• Mile 3 PFI-M325 has a rated total runtime of ≥11 hours, while Mile 3 PFI-M625 and Mile 3 PFI-M625 LRF have rated totals of ≥10 hours. All these figures are combined runtimes across two included rechargeable 18650 batteries at 25°C (77°F); they do not establish a per-battery runtime advantage over Mile 2 or Arc LRF.
• Limits. The matched Mile 3 pair has different listed battery-excluded weight limits: ≤313 g for Mile 3 PFI-M625 LRF, compared with ≤290 g for Mile 3 PFI-M625.
• Best Uses. Choose Mile 3 PFI-M625 LRF when your requirements include 640 × 512 resolution and laser ranging. For a narrower frame, Mile 3 PFI-M335 combines a 384 × 288 detector with a 35 mm lens and a 13.6 × 10.3 m view at 100 m. Mile 3 PFI-M325 gives you the same detector resolution with a 25 mm lens and a wider 19.3 × 14.3 m view.

Mile 2: Strengths, Limits and Uses

• Strengths. Our Mile 2 thermal monoculars include manual-focus 25 mm models at both 384 × 288 (Mile 2 PFI-M425) and 640 × 512 (Mile 2 PFI-M625). Their fields of view match the corresponding 25 mm Arc LRF models. Each has a 3,200 mAh rechargeable lithium battery.
• Limits. These two 25 mm Mile 2 models have higher published NETD thresholds than the matched Mile 3 and Arc LRF models. If laser ranging is essential, confirm that capability for the exact Mile 2 model before buying.
• Best Uses. Choose Mile 2 PFI-M425 when you want manual focus, a 25 mm lens and 384 × 288 resolution with a rated operating time of ≥8 hours. Choose Mile 2 PFI-M625 when you want 640 × 512 resolution and its wider 30.7 × 24.6 m frame at 100 m; its operating-time rating is ≥6.5 hours.
• For the smaller 256 × 192 alternatives, choose Mile 2 PFI-M215 for fixed focus or Mile 2 PFI-M215M for manual focus. Both have 15 mm lenses, a 20.5 × 15.4 m view at 100 m, ≤35 mK NETD at f/1.0 and a 3,200 mAh rechargeable lithium battery rated for ≥8.5 hours. Their listed net weights are <270 g (0.60 lb) for Mile 2 PFI-M215 and <300 g (0.66 lb) for Mile 2 PFI-M215M.

Arc LRF: Strengths, Limits and Uses

• Strengths. Our Arc LRF thermal monoculars provide laser-ranging options across different lens configurations. Arc LRF PFI-A425P LRF combines a 384 × 288 detector with a 25 mm lens; Arc LRF PFI-A625P LRF combines 640 × 512 with a 25 mm lens. Each has manual focus, a 1,000 m laser-ranging specification, one replaceable 3,200 mAh 18650 battery and a 0.41-inch OLED display. Rated operating times on that single battery are ≥7.5 hours for Arc LRF PFI-A425P LRF and ≥6 hours for Arc LRF PFI-A625P LRF.
• Limits. Arc LRF PFI-A625P LRF has a listed battery-excluded weight of ≤370 g, compared with ≤313 g for Mile 3 PFI-M625 LRF. Their fields of view are close: 30.7 × 24.6 m and 30.6 × 24.4 m at 100 m, respectively. Arc LRF PFI-A625P LRF therefore deserves particular attention to its carry-weight specification when you’re comparing these two ranging models.
• Best Uses. Choose Arc LRF PFI-A435P LRF when you want laser ranging with a 35 mm lens and a 384 × 288 detector. Its field of view is 13.2 × 9.9 m at 100 m. If you want the same focal length with a 640 × 512 detector and a broader frame, Arc LRF PFI-A635P LRF provides a 21.9 × 17.6 m view at 100 m.
