I've just had a GQ50L, XQ50F and an XQ35 out for a quick test. Both of the 50s give an incredible image and were picking a strong heat signature from sheep 1000m away. The Hikmicro gave a very slightly better image with a tiny bit more detail, however there wasn't much in it. The Hic thermal sits better in the hand. The XQ35 is superb value at £1000 less, it was also picking up the sheep at 1000m, but not showing anywhere near the detail. Still a top product considering the price
