• Long‑range hunters pursuing deer, elk or hogs across wide fields and open plains
• Competitive shooters and night hunters requiring precise ranging and ballistic solutions
• Users who want maximum detection (~2.6 km) from a 640‑sensor Adder

• Dense timber or close‑quarters hunting where 3.5× base is too much magnification
• Weight‑sensitive setups – the larger lens and dual batteries add heft
• Budgets that don’t need maximum range; the 35‑640 LRF is more affordable

Compared with the 35‑640 LRF, the 50‑640 increases the objective diameter from 35 mm to 50 mm and base magnification from 2.5× to 3.5×. This yields detection rated up to ~2,600 m versus ~1,800 m and enhances long‑range clarity. However, the field of view narrows to 8.8° × 7.0° and the scope gains weight.

The 50‑640 LRF uses a 50 mm lens and 3.5× base magnification to extend detection by roughly ~800 m over the 35‑640 LRF. It remains heavier and pricier but offers greater detail at distance.

Field reports praise the 50‑640 LRF for its bright, detailed image and accurate rangefinding. Users easily identify deer and hogs beyond ~1,000 yards and appreciate the 3.5× base when shooting at extended ranges. The ballistic calculator simplifies holdovers once you’ve ranged the target. Battery life is about 9 hours, though the heavier lens adds weight.

• Wi‑Fi streaming and mobile app integration
• IP67‑rated aluminium housing with 5‑year warranty

The AGM AdderV2 LRF 50-640 combines a traditional 30 mm scope layout with integrated laser rangefinding. Its 50 mm germanium lens and 3.5× base magnification suit buyers who prefer a closer starting view. The 640×512, 12 µm sensor has sub-15 mK thermal sensitivity, helping distinguish small temperature differences. A 2560×2560 OLED display presents the image, but it does not change the sensor’s resolution. Detection is not positive animal identification.

The rangefinder is built into the front lens assembly, avoiding an external LRF housing. An onboard ballistic calculator uses configured data to calculate a correction. Shutterless NUC maintains viewing during image calibration, while optional 0.5× zoom increments let you adjust the view gradually. Digital zoom enlarges existing image detail. Video and audio recording, 64 GB storage, picture-in-picture and Wi-Fi connectivity make it easy to review and share recordings.

AGM rates the rechargeable internal and removable 18650 battery system for up to nine hours. USB-C external power is also supported. The included ADM Recon one-piece 30 mm mount and IP67 housing round out the package. Choose this model for its traditional layout and integrated features; a compact Rattler may suit you better if size and weight are priorities.
