[Roof] very easy to use. Locks on target quickly and easily. Battery usage much better than expected. Used 5 rounds and battery still shows full charge. Very clear picture. works well with unsteady hands. Only drawback is no magnet mount for cart.

[1x Built-In] I've owned some of the most popular rangefinders and used most of the rest at one time or another while playing golf with others. As a longtime Canon user, I was happy they jumped into this category with their optics and technology.
As a rangefinder:
+ Locks onto pin with prism immediately. -Faster than all the rest I've ever used, it's actually quite surprising how fast it locks on.
+ Unit vibrates when lock is established.
+ Numbers are crisp and easy to see in viewfinder. Integrated diopter adjustment for those who need it like me.
+ Unit is small, lightweight and fits in back pocket - I mostly walk while playing and wanted a small form factor. Always wondered why most of them are not smaller. Not an issue in my hand to hold steady while taking readings with image stabilization.
+ Rechargeable battery via USB C (no more searching for CR2s). Battery charge icon is lit in viewfinder each time unit is utilized.
+ Zoom function is handy to located far targets and even help identify golf balls- was on the tee side of a creek and wasn't sure whose ball carried the hazard. Used the zoom function to identify the ball from 20 yards away.
+Canon menu is simple to navigate and set the unit/change and modify.
+ Camera is an added bonus; I did not purchase it for that function but have used it and works to my expectations with a small handheld device. Same with the video.
- Only option that some will miss is the internal magnet that other brands have to enable the unit to be put on the support bar of a golf car and help you forget your rangefinder after golf.

[7x] Very affordable triagonal prism, which is big enough for fitting any lens, and strong enough to be handled roughly. Cleans out very easily.

[OLED] Very fast to read. Ultra clear display

[1x Built-In] Excellent sight. Easy to install. Fast shipping. Good service from B & H.

[Roof] This is my 3rd rangefinder. I have a Callaway with no slope and bought a value rangefinder with slope and it was inaccurate and was easily put into meters. I decided to buy a highly recommended one and looked at the Bushnell's as they seem to be everyone's favorite. I liked the size of the Nikon better and was a little bit less money. It is very accurate and the stabilization is great. Easy to turn off the slope for competition and light indicator let's competitors know it's off.

[Monocular] ued it many times works well

[1.46 lb] My 15-year-old Nikon rangefinder couldn't lock onto the flag unless it was blowing in the wind, which was frustrating. The 50i solved this issue, plus it indicates the ball-path yardage based on elevation change.

[Monocular] 5 star

[1.46 lb] This is the 4th rangefinder I have purchased over the last 25 years or so...And this is by far the best.


Nikon quality optics, clear display, light weight and very accurate. I have purchased other name brand RF, but this one, especially when bought while on sale...surpasses them all.
New features, e.g., slope measurement, flagstick lock-on and variable brightness settings are great.
I highly recommend this laser rangefinder.
