I've used several rangefinders on my travels and this one is by far the easiest to use with one hand. The focus wheel at the top of the rangefinder can be adjusted with just your index finger, while the meter and mode buttons at the bottom can be operated entirely with your thumb. This one-handed operation is particularly useful for eyeglass wearers like me, as it virtually eliminates the common smudges that result from having to adjust the image with one hand while trying to steady the rangefinder with the other. The interface is simple and intuitive, with discrete functions to control distance, angle, and speed. The accuracy is among the best I've seen, adjustable to tenths of a degree. I like the lock-on mode that locks on a specific target. USB-C charging is a great convenience for me. It can be charged anywhere - at home, in the car, in a coffee shop, etc. I really appreciate not having to keep changing batteries. Overall, the picture is clear and true to color, ideal for either watching the game or just enjoying the scenery. The range finder is extremely compact and lightweight, yet robust. It comes with a protective cloth pouch and is small enough to fit in a pocket, backpack or gear bag.
