Review on 🎯 Uineye Laser Rangefinder: Accurate 1312-1950 Yard Range for Hunting, Golf & Engineering Survey with Height, Angle, & Horizontal Distance Measurement by David Shah

Uineye sells several models of these golf laser rangefinders with different maximum distances (up to 1800 meters). The further the maximum distance of the range finder, the higher the cost. I bought a 1200 meter range finder that uses two AAA batteries. Long range instruments use a CR2 battery. The device shuts down fairly quickly after a period of non-use, saving batteries that last a very long time. I use a range finder to determine the height and distance of trees, for hiking, and for general shooting. It meets the requirements exactly and has performed well. When you turn on the instrument and take measurements, it shows the distance to the object in a straight line (in yards or meters) and the angle to the horizontal (positive - up, negative - down). If you first press the mode button, the equivalent horizontal distance ("level") and vertical height ("high") are also displayed. All measurements are displayed to the nearest tenth of a yard, meter or degree. The company claims distances are accurate to 0.33 yards (1 foot) and angles to 0.35 degrees. I checked the range from 4 to 100 yards and it was measured as follows: 4 years = 3.9 years, 16 years = 15.9 years, 50 years = 50.7 years, 100 years = 100.4 years. I find it hard to believe it will maintain its claimed 1 foot accuracy to hundreds of yards. The 1312 yard range finder is said to measure from 5 to 1312 yards; In fact, it is displayed from 3.8 yards to around 1400 yards (above 1000 yards it can be difficult to get a reading). Scan mode displays continuous readings as you move the rangefinder across different targets. To measure the height of a tree or other object, simply measure the top, then the bottom, and concatenate the two vertical heights. The only calibration you can do is angle, which is done in a horizontal position. (0.0 degrees). I calibrated it in the morning and sometimes found it to be off by a few tenths of a degree at the end of the day. But it's usually accurate and doesn't require recalibration. It will be calibrated upon purchase. But to calibrate it yourself accurately, you can use the usual carpenter's or tripod spirit level. You can also calibrate it fairly easily by finding a flat spot (like inside a building) and shooting at the marked spot on the wall at eye level, then shooting in the opposite direction to check. As another reviewer mentioned, it's very handy in its carrying case, and you can tape the battery cover over it to keep it from opening. I keep my range finder in a zippered pouch that makes it easy to slip in and out of the bag. The device is small enough that I usually just carry it in a Ziploc in a large shirt pocket. The eyepiece has a focus ring so you always get a sharp image. The numbers on the screen are easy to read and remain on the screen for about 15 seconds after the measurement; So if the view is dark or at night you can just redirect the tool to a brighter object and just read the numbers before they disappear. The 8x monocular is very clear, but I don't have steady hands, so I usually take a few readings on my target. Even with shaky hands, measurements are well reproducible to at least 100 yards, within about 0.5 yards. The rangefinder struggles when you're measuring an object with branches or tall grass in front or to the side, and also rarely in normal sunlight (don't know why). In these cases it either gives you no reading or wrong readings e.g. B. 5 times the correct distance. But in those few cases, I've always found ways to work around the situation. Overall, I'm really enjoying using this range finder. It has all the features I was looking for and it's small and light.
