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. Naše 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. Naše 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. Naše 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.
