The Infiray Tube TH35 is a great short to medium range 464 x 464 pixel thermal, it has a 35mm lens with a higher base mag of 3x which allows for good quality image and accuracy at close to mid range distance from 35m out to 200m, offering a relative narrow field of view. A good choice for Deer, Kangaroo and pig Harvesters as well as recreational pursuits; a great mid range device that would offer good head accuracy for game meat harvesters. Close to mid range moving targets are harder due to higher base mag but not out of the question. Overall its a great value for money unit for those that can’t afford the next step up. All units in the Tube series are easily mounted using traditional 30mm rings often fitted to a picatinny or weaver base rail. The stand out feature of the TH35 is its industry first round 1.39 inch screen with a whopping 2560px × 2560px display, offering a next level viewing experience. The TH50 includes Two built-in 18650 batteries + one replaceable 18500 battery with a running time of up to 11 hours. The traditional-style 30mm Tube meets the needs of professional hunters who value traditions and seek technological superiority, ensure an extreme detection range of up to 1816 meters.
