The Infiray Tube TL35 is a great short to medium range 384×288 pixel thermal, it has a 35mm lens with a higher base mag of 3.1 which allows for decent quality image and accuracy at close to mid range distance from 35m out to 150m, offering a relative narrow field of view. A Low Budget choice for Deer, Kangaroo and pig Harvesters as well as recreational pursuits; we do recommend game harvesters to consider a different model. Not the best for longer range targets and head accuracy can be limited to mid range. Close to mid range moving targets are harder due to higher base mag but not out of the question. Overall its a great budget optic 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 TL35 has 1280px x 960px LCOS display that offers a good viewing experience, in addition it includes Two built-in 18650 batteries and one replaceable 18500 battery; with a running time of up to 15 hours. The traditional-style 30mm Tube meets the needs of hunters who value traditions and seek technological superiority, ensure an extreme detection range of up to 1816 meters.
