Getting Started: Unboxing and First Steps
Opening the box is exciting, but let’s make sure we do the setup correctly. Most Bozily models come with the rangefinder itself, a protective case, a CR2 battery, a lens cloth, and a lanyard. The first thing you need to do is install the battery.
Look for the battery compartment, which usually has a small tab you can lift and twist. Pay close attention to the diagram inside - it will show a '+' and a '-' to indicate the correct orientation. Pop the battery in, secure the cover, and you're ready for the most important step that nearly everyone gets wrong at first: focusing the eyepiece.
The Single Most Important Setup Step: Adjusting the Diopter
Before you even try to get a yardage, you need to calibrate the display to your own vision. This is done with the adjustable eyepiece, also called the diopter. Don't look through the lens at a distant object yet. Instead, press the power button once and look at the display itself - the numbers, the crosshairs, and any icons that appear.
Is the text perfectly crisp and sharp? If not, twist the eyepiece ring left or right until everything on the internal screen is in sharp focus for your eye. Once that’s done, you won't have to touch it again unless you share the device with someone else. A blurry display is one of the most common "problems" new users face, and this simple adjustment fixes it instantly.
Switching Between Yards and Meters
Your Bozily rangefinder can display distances in both yards and meters. Typically, you can switch between the two units of measurement by pressing and holding the "Mode" button for a few seconds. The display will flash between 'Y' for yards and 'M' for meters. Stop on the one you prefer, and you're all set. In the U.S. and U.K., yards are standard for golf.

Your rangefinder is more than a simple point-and-shoot device. Understanding its different modes is how you unlock its full potential on the course. You'll switch between these modes by a short press of the "Mode" button (the one that isn't the power button).
Mode 1: General Ranging
This is the default mode. It’s for general use and will give you the distance to any large target you point it at. Think of it as your "scouting" tool.
Aim the crosshairs at a target, like the front of a fairway bunker or a large tree you need to carry.
Press the power button once.
The distance will instantly appear on the display.
This mode is fantastic for getting lay-up numbers or figuring out the distance to hazards. If you want to know how far it is to the front edge of the water, this is the mode to use. It’s quick, simple, and effective.
Mode 2: Pin-Seeking with Flag-Lock (Golf Mode)
This is the money-maker and the mode you'll use for most of your approach shots. It's designed specifically to isolate a slender target like a flagstick from a busy background of trees and hills. Golf courses are full of visual noise, and this mode cuts right through it.
Here’s how to use it expertly:
Make sure you are in "Golf Mode." You'll usually see an icon of a flagstick on the display.
Aim the crosshairs slightly to the side of the flag, at the background behind the green (e.g., the trees).
Press and hold down the power button.
While holding the button, slowly pan the crosshairs across the flagstick.
Your Bozily will emit a short vibration, or "jolt," and the display will lock onto the distance of the closest object it found - which is the pin.
This process of scanning from the background onto the pin is the most reliable way to use this technology. By doing this, you are telling the device to ignore the farther objects (the trees) and lock onto the nearest one (the flag). That tactile vibration is your confirmation that you've got the right number. You can swing with total confidence.
Mode 3: Slope Compensation
This is an incredible feature that acts like a veteran caddie whispering in your ear. Slope mode reads the actual, line-of-sight distance and then calculates what that yardage will actually play like based on the change in elevation.
When you're in Slope mode, you'll see two numbers on the display:
The Actual Distance: This will be the main, larger number. It’s the true, straight-line distance from you to the target.
The "Plays-Like" Distance: This will be a second number, often next to an angle measurement or a small icon of a ramp. This is the number you should base your club selection on.
A perfect example: You laser the flag and it reads 140 yards. But it’s an uphill shot. Your rangefinder shows the actual distance of '140y' and a slope-adjusted distance of '152y'. This means you shouldn't grab your normal 140-yard club, you need to club up and hit the shot as if it were 152 yards. It takes all the guesswork out of uphill and downhill shots, which is where amateurs often make critical mistakes.
A note on tournament play: Many formal competitions prohibit the use of slope-compensating devices. Most modern Bozily rangefinders feature an external switch on the side of the unit that you can slide to disable the slope function, making it legal for tournament use. Just be sure to check the local rules for any event you play in.
Plan every shot like a pro

Having a rangefinder is about more than just finding the distance to the hole. The best golfers use it to gather information and build a strategy for every shot.
Scan the Landscape
Don't just shoot the pin. Before your approach shot, gather a few key numbers to map out your target area:
Yardage to the front edge of the green. This is your "must carry" number.
Yardage to the back edge of the green. This tells you how much room you have to work with.
Yardage to carry a bunker or clear a water hazard.
Distance to a part of the green far away from the pin, if the pin is in a dangerous spot. A 30-foot putt from the middle of the green is always better than a short-sided chip from deep rough.
Tips for Stable Aiming
If you find that your hands are a bit shaky (especially on a cold morning!), getting a steady lock can be difficult. Here are a few coaching tips:
Use Two Hands: Hold the rangefinder with both hands for a more stable base, just like you would with a pair of binoculars.
Brace Yourself: Stand with a solid golf posture and try tucking your elbow into your ribs or chest. This triangle creates a much more stable platform.
Use Your Cart: If you're in a golf cart, rest the base of your hand or the rangefinder itself on the steering wheel or windshield frame to eliminate any shaking.
Care and Maintenance
Your rangefinder is a precision instrument. Treat it well. Use the provided soft case to protect it when it’s bouncing around in your bag. If the lenses get smudged or dusty, use the provided microfiber cloth to clean them gently - don’t use a towel or your shirt, which can scratch the coating. Finally, turn it off and store it without the battery if you won't be using it for an extended period to prevent any battery leakage issues.
