I just got it, it is given to a 18X52mm for just 6 more than the above.
Please note that the user guide is in Chinese and it turns out that this is a 1.5-18X52mm telescope (18 being the infinity on the device). I put the zoom to maximum sharpness and I have settled on a 150m target. Ja took my rifle with a telescope and 4-12x50 i pointed the same target, with zoom 12. I looked at the difference between optical and 2 i dropped my glass to have the same vision as the monocular we had between 8 and 10.
I put a white dot on the 10th of the monocular and if we decrease the zoom, we arrive at 3 so we 3-10X52 a telescope.
I'll see to the use and dusk, but for now, for the price, this is robust and that is of good quality, it is also given waterproof, even if nest Quà rain, it's not bad.
So still happy for this purchase to 18.
