Are you looking to get a new rangefinder that gives slope?

  1. Your current one measures distance but does not factor in the inclines and declines that obviously play a part in the game.
  2. Everyone keeps throwing the word “slope” around when it comes to rangefinders. You don’t know why it matters but you know it does.


3. You are looking to replace a decent device with one that will outdo it. This might just be the way to do it.

There are a variety of reasons why you could be searching for this product. No matter what your reason is, getting the right product counts for more than we give it credit for.

In A Hurry?

I know it is just 5, but even that does not completely do away with the issue of indecision. This can be even worse when you have no experience of using these products or any product that is similar.

To help those that would rather not endure this struggle, we put these 5 against each other in a quest to choose the ultimate one.

After scrutiny and comparison, we have settled on one that we can fully stand behind.

Our top pick is the Callaway 300 Pro Golf Laser Rangefinder.

It is made by a brand that we have used for a while and know to produce good quality products. It measures range for a distance of up to 1000 yards.

You can get these measurements in metres as well if you would prefer. It comes equipped with an LCD screen that makes it easier for you to read the information presented to you.

Our top 5 Golf Rangefinders With Slope

When you are striking a ball from a high or low position on the golf course you know that this has a effect on how far the ball will go. When this is not considered in the distance that you get out of your device, you decisionmaking will also be based on a faulty premise. If the incline means that the distance is a little longer, you may need to use extra force to get the ball to go as far as you need it to.

Where there is a decline, you may need to reduce the amount of force that you use. Except, you would not know that when using a regular rangefinder. There is a reason why these devices are not permitted in tournaments. USGA recognises the power that they hand to the golfer. Perhaps another thing is that this would lead to more and more technology becoming a massive factor in golf at the top level. At least most of us do not have to concern ourselves with it. If you are practising, getting your slope measured will train you to pick the right clubs at the right. Even if you are to then play in a tournament, your judgement will be based on what you have previously learned from your rangefinder.

There are many devices on the market that can deliver this function to you. This is a great thing. We all love to have options. The downside of it is that it also makes it much harder for us to find the right one. We have spent a lot of time to make sure that you do not have to face this issue. We started off by researching product, before going on to test them. Through this process, we were able to pick 5 products that are very good.

Golf Rangefinders With Slope Buyer’s Guide

You will likely have an idea of which one of the top 5 picks you will be purchasing. They have been reviewed above in some detail. Their upsides and downsides have been presented to you. Yet, we are aware that decisions do not always work that way. Perhaps you have come out with more questions as you have been reading about these products. Some of the terms used to describe them may be entirely new to you. That is alright. We cannot all be golf nerds.

The purpose of this buyer’s guide is to provide you with more information in relation to these products. We will be tackling some of the most asked questions about them. Terminology and how things work will also be covered. Our aim is for you to be confident enough to make an informed purchase at the end of this guide. Some of the things that we considered before reaching our decision are covered by these.

Golf Slopes: Incline and Decline

There are two kinds of slope that you will hear about in golf. One refers to the difficulty of a certain golf course. It is given a slope rating and a handicap. The lower the handicap the more difficult a course it. Another form of the slope is the natural English definition of the word. It refers to the elevation or height of two different points in the ground. Where the next place is more elevated than where you are, one can say that there is an incline in slope. Where the other point is lower, one can say that there is a decline in slope. This is what the rangefinders referred to in this article are used for measuring.

Any shot that you take will encounter some resistance from the slope. It may encounter it on the ground when you are putting or after it has landed in the case of your long shots. This is a difficult thing to gauge with the naked eye. Golfers end up hitting the ball too hard or without enough strength. The results are either the ball rolling too far because of the decline that you had not considered. Or the ball not going as far as you would have hoped, because of an incline that you did not consider.

How do you turn off the slope on a Bushnell v4?

The power button on the Bushnell V4 has various functions. This makes it difficult for some users to figure out how to use it as a button to switch the device’s slope off. This is one of the two things that we expect it to do. We want to be able to switch the slope on when we need it and off when we are not permitted to use it.

You simply need to hold the power button for a prolonged period. The device will take you through all the modes. The option that you are waiting for is labelled “no slope meters”. Once you see that, let go of the button. Your slope will now be off. You are now complying with USGA’s rules and can use the device in a tournament.

Are rangefinders allowed in golf tournaments?

Yes, you are allowed to use rangefinders in golf tournaments. The USGA’s guidelines prohibit the use of the rangefinder that measures slope. If you rangefinder does not measure slope or has this function switched off, you will be able to use it in a tournament. In some cases, you will find that the organisers of the tournament may not allow the use of rangefinders at all. So, generally yes, but, here are some situations where you cannot.

Do rangefinders work at night?

Most golfers will not play at night so this question may not necessarily be for them. If you use your rangefinder at night you will find that the laser still works. It does not depend much on lighting. The difficulty will be with you being able to read the data that it comes back with. If your screen is particularly bright, this will not be a bother. You may also be able to introduce a torch to solve the lighting issue.

Final Words

We have presented you with 5 rangefinders that measure slope. If you were to buy any of these, you would be pleased with the service that they deliver. We also picked a top one for you, if you are not keen on doing the selection for yourself. You are encouraged to take the time to read each of the reviews of these devices. Not only will you get to know their ins and outs. You will also be able to learn more about rangefinders in general. Each review includes the good and bad aspects of the rangefinders, based on our research and testing. Reading them will make you aware of these and factor them in your decisions.

We have also included a buyer’s guide. This is for those that have some extra questions that may have come up while reading about these devices. We have answered some of these pressing questions. Our hope is that you will be confident about how much information you have been provided. Whatever choice you end up making should be based on a vast amount of information.

Just to reiterate the key factors that we considered include:

  1. The simplicity of use.
  2. Range measured.
  3. Level of accuracy.
  4. Batteries.
  5. Target locking mechanism.

On top of the usual functionality of checking that the device actually measures slope, the five aspects above will go a long way in ensuring that you end up with a good device. You want a device that is not difficult to use. In all fairness, most rangefinders are made to be simple.

The range measured will tell you how close or far you would need to be from a target for you to get accurate data. The greater the distance is in most cases. This will also tie into the level of accuracy. If the device measures thousands of yards inaccurately, it is inferior to one that measures hundreds of yards accurately.

Batteries are surprisingly an issue here. I still cannot wrap my head around manufacturers who do not provide their device with a battery. It is pitiful. If you can get a device with a battery, that is always better than having to buy one. A rechargeable battery would be my pick, where possible. It is just less hassle.

The target locking mechanism speaks of how a device works when you are trying to pinpoint let’s say a flagpole. Most of the good ones have a jolting effect. They give a vibrating motion to let you know when you have picked it up. This lets you know that the measurement will likely be accurate and that you no longer have to try and keep your hands steady. If you can get one that alerts you in one way or another, it will go a long way.

If you consider all of these things together with the factors that we covered in the product reviews, you will be able to get yourself a great rangefinder. Until next time. Happy Golfing.
