Probably the BIGGEST benefit to owning any thermal device is detecting animals (or people) at a VERY LONG RANGE. In any weather, day or night, without you being spotted or disturbing the the wildlife you're hoping to see. And there is no better way of detecting at a very long range than the Pulsar Merger thermal binoculars. In this field test we compare the entry level Merger LRF XQ35, with the mid price Merger LRF XP50 and the premium Merger LRF XL50 at a whopping 1,380m... in 89% humidity. See lots of side-by-side field test footage, showing you exactly how the different Pulsar Mergers compare. And there's a surprise at the end... it's not just a person we're able to spot at that BIG RANGE! There are lots of other MEGA tests too - so subscribe of you want to see more. NOTE: To get a truer view of the image you'll see if you're serious about buying some Pulsar Merger thermal binoculars MAKE SURE YOU CHANGE YOUR YOUTUBE VIDEO SETTINGS (the cog below the video) to the best quality setting available. And to see the very small objects 1.4km away, that are obvious through the eyepiece, ideally watch this on a PC rather than your phone.
