This will help make fixing and maintaining your rangefinder easy and simple so you can see clear results out on the course as soon as possible.

Golf Rangefinders: Parts And Pieces

Before you can start fixing your golf rangefinder, you should first get to grips with all its bits and pieces so you know what goes where and what each part does to help you improve your golf game.

Here are some of the features that all rangefinders have that are vital to its usage:

  • Eyecup – this is where you press your eye against your rangefinder so you can look through it and use it to find the area you want to aim for with your next swing.
  • Strap – most rangefinders come with some kind of attached strap so you can easily hold it and carry it around without potentially dropping and damaging it.
  • Battery Chamber – this is where the battery is kept. It should be easily accessible.
  • Objective Lenses – these are the lenses you look through to find your next desired area.
  • Power Button – the button used to turn your golf rangefinder on and off.

When you go to use your rangefinder, it is always handy to check these parts over first. Ensure that your battery is charged and that nothing is visually damaged or broken before use. If there is an issue, you can then move on to fix it.

Rangefinders And Common Problems

Now, we are going to go through some of the most common problems a lot of people have with rangefinders.

This way, you can recognize the symptoms yourself and be able to follow through the steps so you can quickly fix your rangefinder without having to fork out for repairs – or even, a completely new rangefinder.

Learning to fix your rangefinder yourself can save you a lot of money, plus some of the most common issues are easy to fix all by yourself. So, let’s take a look at some of these issues and what you can do to solve them.

Blank Display

This is probably one of the most common problems when it comes to using your rangefinder.

You’ve gone to use your rangefinder, powered it up and – nothing. The display screen is completely blank. So, can you fix this?

First, try changing the mode. Rangefinders often come with different modes like target priority mode or pin seeking mode. These are featured to help you get the most out of your range finder and make it more versatile, so you can use it on lots of different kinds of courses.

If you try changing the mode, it could boot up the rangefinder and kick it into gear for you. This is how most people fix this issue but if it still fails, then it’s time to look elsewhere for a solution.

First, read through your manual to see if there are any back-up booting options like holding certain buttons down for a longer period of time. If not or your display screen still is not working, then it’s time to look inside the rangefinder for the issue.

The reason behind your blank display could be loose connections inside your rangefinder. This is when most golfers would take their rangefinders to a professional for them to fix it.

This is because to fix those loose connections, you will have to open up the rangefinder and fix them manually. However, if you try to do this step yourself, you could end up causing more damage than you are fixing.

So, if loose connections seem to be the problem, take your rangefinder to a professional.

Not Capturing Your Target

This is the worst issue for your rangefinder to have because it can be caused by a number of different reasons.

So, if your rangefinder is failing to focus on the target properly, try going through these steps to find which issue is causing your rangefinder to fail at pinpointing your exact target.

The first cause of this issue could be dirty lenses. Dirt and debris can interfere with your rangefinder’s pinpoint mode and make it difficult to properly read the laser. So, give your lenses a clean and make sure that you regularly clean them to avoid this issue in the future.

To clean your lenses, you can use a cleaning cloth used to clean glasses or the one your golf rangefinder was supplied with. You can also use a lens cleaning fluid to give it a good polish. It’s just like cleaning a pair of glasses – it’s very easy to do!

If dirty lenses are not the cause, it could be due to a weak battery. All batteries degrade over time so if you have had your rangefinder for a while, this issue is bound to pop up eventually.

Replacement batteries are easy to purchase but first, check that your battery is properly placed in its chamber. You can open up the battery chamber yourself and reconnect the battery.

This might fix the issue but if you notice anything like broken wires or connectors, these will probably need smoldering back in place. Unless you are confident with smoldering yourself, you will have to take your rangefinder to a professional for it to be fixed.

No Readings Of Faulty Readings

These two issues are very similar. You’ve gone to use your rangefinder, pinpointed the target, and the readings are coming back … well, they either just don’t make sense, or there are no readings at all.

The solution to these problems are, luckily, very simple. Sometimes, all you need to do is switch modes (make sure that you were in the right mode originally) and consult the manual to make sure that you are choosing the correct mode for your use.

If changing the mode does not help, try giving the lenses a clean. It could be that dust or debris are giving your rangefinder false readings, so wiping it away will clear your lenses so your rangefinder and properly see your target.

Sometimes, lenses may need replacing if they are cracked or old. They are harder to come by than replacement batteries so contacting the manufacturer directly is probably the best way to find new lenses.

You can replace the lenses yourself by deconstructing your rangefinder and swapping the lenses yourself, or you can take it to a professional to reduce the risk of you causing further damage. It all depends on how confident you are with fixing gadgets.


And that is how you can fix some of the most common issues with your rangefinder!

Knowing that sometimes, it just takes a few clicks of a button to fix what seems like a damning issue is such a huge relief. This can save you a lot of time and money going to a professional too!

Just remember to maintain your rangefinder and clean the lenses frequently. This will help you avoid certain issues so you can keep golfing happily and improve your game using your handy little rangefinder!
