Fetch Falcon10x50 BAK4 FMC 船用 IPX7 双筒望远镜（2023 测距仪、数字指南针和温度紧凑型）多功能船用带背带和颈带

I really like them as binoculars but I did not realize the "built in rangefinder" is based on marine use.As an example it is like a golf manual rangefinder where the height of the distant object " like a flag pole on the green is known.So the scale is permanently in the right lens .Prior to ordering I mistakenly envisioned it was used like a hand held rangefinder which sends a signal to target object and calculates distance from time it takes for signal to return.Having said that the description did not fully explain how the rangefinder worked to potential customers.Again great binoculars for knowledgeable mariners but not for hunters and hikers.

The picture quality is great up close, true HD. Anything 50 yards and over though becomes blurry, even seeing doubles. I've adjusted a fair share of binoculars in my life and I could not correct these. Looking at anything in the distance made me dizzy.The construction feels solid and I had high hopes but ended up being disappointed.

Belle image mais mes jumelles avait deux taches sur la lentille droite donc je les ai retourné.
