10 Best Golf Rangefinders with Slope of 2020 – Reviews & Top Picks

Last Updated on November 18, 2020

TecTecTec Laser Golf Rangefinder

Rangefinders provide important information on a wide range of environmental landmarks on the golf course. Really good units supply distances, and can even account for wind and elevation. Experienced players know that a few yards can mean the difference between a birdie, and a double bogie, so these stats are no joke.

Unfortunately, though, not all rangefinders are equal. While a good product will effectively fulfill the duties of a PGA Tour caddie, a subpar unit may actually be counterintuitive, supplying you inaccurate numbers that jeopardize your game.

The products highlighted today are accurate and effective. Read on for some golf rangefinder with slope reviews!

  • The 10 Best Golf Rangefinders with Slope – Reviews 2020

    1. TecTecTec Laser Golf Rangefinder – Best Overall


    TecTecTec is known for making very high-end rangefinders that are typically available at a competitive price. Such is the case here. The VPR0500S features an impressive range of 540 yards—more than enough for even lengthy par 5s.

    It benefits from pin sensor technology that produces a sharp vibration when you lock onto the flagstick. This feature is great because it allows you to be confident that you’re getting a read to the hole—not a tree branch behind it.r

    And of course, there is also the slope mode. Like all of the products on this list, the TecTecTec adjusts its readings relative to the slope of your position, making it much easier to accurately select a club. Slope mode can then be deactivated during tournament play to keep it in compliance with the USGA rules.

    The lens is able to be magnified by 6X, helping you to get a good look at the nuances of the green, as well as other important features of the course.

    The only downside to this instrument is that the actual optical quality is a little bit lacking. The image rendering isn’t as vivid as it could be, though it should be sufficient enough for you to comprehend what you’re looking at.

    • 6X magnification
    • Slope mode that can deactivate for tournament play
    • Affordable price tag
    • Pin locking mode
    • Optic quality is a little bit lacking

    2. Saybien Golf Rangefinder – Best Value


    The Saybien’s features lend themselves equally well to both golf and hunting. The measuring laser features a massive range of 1,200 yards—more than enough for evaluating even the longest holes on the planet (several times over, in fact).

    It also features a “continuous scan” mode that is particularly well suited for hunting. This component means the device is always taking data, so when you actually identify a target, the stats are available in the blink of an eye.

    The laser also accounts for slope, making it easier to tell how a shot will play.

    We also really like the battery situation. While many rangefinders require pricey batteries that often need to be replaced, this one can be charged via a USB port, making it convenient and economical. Indeed, the price of this rangefinder is also very friendly to the pocketbook, which is why the Sabien earned the distinction of being our best golf rangefinder with slope for the money.

    The big issue is that it can be very challenging to actually lock onto your target. Users report that it sometimes takes several minutes to hit the flag. This issue is offset somewhat by a pin seeking “jolt” that notifies you when you’ve hit your mark. However, the delay can be frustrating all the same.

    • Affordable
    • 1,200-yard range
    • Slope measurement
    • USB port charge
    • Very hard to lock in on the target

    3. Leupold Gx 5I3 Golf Rangefinder – Premium Choice


    The Leupold comes loaded with all the fixings. Potential buyers may first notice the overall build quality. The unit is armored with a durable rubber coating and made to be resistant to fog and moisture. You probably won’t want to take it for a swim, but a rainy day on the course probably won’t be an issue.

    The unit also features a comfortable rubber eyepiece that will be cozy for long periods of use. In terms of actual scanning, there is a good deal to admire. Like some of the other options on our list, it features a continuous scan mode that helps render measurements very quickly.

    Readings are accurate to within one-third of a yard, and the unit can even go so far as to recommend a club for you. Simply punch in the average distance that you hit each club, and the Leupold will provide a recommendation with each reading. These recommendations also account for slope.

    Finally, the lens is also really great. It features a special coating that produces excellent image quality.

    The only real issue is the price. This unit is several times more expensive than many of the other options featured here today.

    • Great build quality
    • Recommends clubs
    • Super accurate
    • Accounts for slope
    • Fast readings
    • Excellent optical quality
    • Very pricey

    4. Precision NX7 Pro Slope Golf Rangefinder

    Precision Pro

    The Precision Pro is a more moderately priced product that still packs in a wide range of great features. The unit has a 400-yard range and is accurate to within one-tenth of a yard. Measurements take slope into account to help you pick the right club for any situation.

    The lens can be magnified up to 6X and jolts with a vibration when you lock onto the pin. It also comes with a very generous lifetime battery replacement guarantee, which will help you save plenty of money in the long run.

    Clarity is a bit of an issue. It may be somewhat challenging to determine exactly what you are looking at. It’s also a bit slower than we care to see. It may take a while to get a distance reading.

    • 400-yard range
    • Moderate price
    • Pin finding jolt
    • Very accurate
    • Battery replacement guarantee
    • A bit slow
    • Optical quality is somewhat lacking

    5. Callaway 300 Pro Golf Laser Rangefinder


    The Callaway features a range of up to 1,000 yards and benefits from a continuous scan mode that gives you info on a variety of different targets at once. This means you can quickly get intel on fairway bunkers, water hazards, and the pin.

    The rangefinder automatically scans for slope, but this mode can be deactivated for tournament play. Callaway has also implemented what they call “birdie mode”—an audible chirp that is emitted whenever you lock onto the flagstick.

    The lens can be magnified by 6X for clear viewing from great distances away, and the exterior is made to be ergonomic for comfortable long term use.

    Many users do complain that it can take a long time to lock onto the target. We’ve also heard reports that the battery is somewhat unreliable, sometimes dying prematurely in the middle of a round.

    • Hard to lock onto a target
    • So so battery

    6. Wosports Golf Rangefinder


    The Wosports features a 650-yard range (though it can also be switched to read in meters). The unit jolts with a vibration when you lock onto a flagstick, but also benefits from a number of features that will be beneficial for hunters.

    It is able to account for fog, slope, and speed (in the context of hunting) giving you hyper-accurate readings on your distance to the green, or to prey.

    The main problem is efficiency. Many people are reporting that it can take five or six attempts to get an accurate reading on the pin.

    The ultimate performance is still pretty effective, but all the delays may grow frustrating over time.

    • 650-yard range
    • Many quality hunting features
    • Pin jolt
    • Efficiency problems

    7. Bushnell BN201760P Tour V4 Golf Laser Rangefinder


    Bushnell has long been considered the gold standard in the world of rangefinders. They are especially celebrated for producing really high-quality lenses. The glass features special coatings that render picture-perfect clarity.

    The unit jolts when you lock onto the flag and features a slope mode that can be deactivated easily for tournament play.

    It has a range of 450 yards and can be magnified up to 6X, making it easy to take a close look at the green.

    The problems pertain to price and are two-fold. For one thing, it is one of the more expensive products featured on our list today. Unfortunately, though, it is also somewhat lacking in terms of value. Some products featured here today are available at half the price while performing the same functions.

    • Great optics
    • Pin jolt
    • 450-yard range
    • 6X magnification
    • Pricey
    • Value concerns

    8. Gogogo Laser Rangefinder

    Gogogo Sport

    The Gogogo is an affordable product that benefits from many familiar features. It utilizes slope mode for accurate measurements and a large 650-yard range that gives you more than enough coverage to navigate any hole on the planet.

    The Gogogo can also be magnified by up to 6X for a more detailed look at various features around the course. Meanwhile, the lenses are coated with a specialty solution that helps to make the most use out of light.

    Unfortunately, it is a very slow product. Readings can take ten seconds or longer to acquire. It may not sound like much at first, but multiply that by 70, and you’re looking at a lot more waiting throughout the course of your round.

    • Affordable
    • 650-yard range
    • 6X
    • Very slow

    9. LaserWorks PRO X7 Golf Rangefinder


    The LaserWorks is a moderately priced product that benefits from the pin locking jolt demonstrated by so many other options on this list. It also features a very unique charging concept. When you aren’t using the rangefinder, you can mount it to the charging station, ensuring that you’re always at full juice. A single charge may produce approximately 5,000 measurements.

    It also accounts for a number of considerations that are ideal for hunting. The unit factors fog, elevation, and the speed of your target into its measurements, in order to produce the most accurate reading possible. The range is 656 yards.

    Unfortunately, the optic quality is very lacking. It also can be very hard to lock onto a target.

    • Great battery
    • Affordable
    • Many features good for hunting
    • Poor image quality
    • Hard to lock onto a target

    10. Tacklife MLR04 Golf Rangefinder


    Finally, the Tacklife. This unit features a 600-yard range and can be magnified up to 6X. It jolts when you lock onto the pin, accounts for slope, and can measure at a variety of different angles (including vertically and horizontally).

    Unfortunately, the performance simply isn’t what we expect to see. It can be very hard to get locked onto the flag, and measurements are often more than a club length (approximately 10-15 yards) off, which can have serious scoring implications.

    • 600-yard range
    • Measures at a range of different angles
    • Not very accurate
    • Very slow

    Buyer’s Guide

    If you found the features illustrated above a little complicated, we get it. A lot goes into a good rangefinder, and it can be hard to understand them all. That is why we’ve put together these handy buying considerations to help make your life a little bit easier.

    Range Doesn’t Matter (Much)

    It’s true. For people using this product exclusively for golf, range matters very little. All you really need is a range that is slightly longer than the maximum distance you can hit your driver. After all, why would you need to take a measurement of something 450 yards away, when you can only hit the ball 250 yards?

    Longer ranges are typically used more by hunters. However, some players may appreciate the ability to get distances on a variety of landmarks so they can plan their holes out better. In that case, you still only need a range of 400-500 yards (as this is roughly the maximum length of most amateur level holes).

    Fortunately, pretty much every product on this list is more than qualified to meet those criteria.

    Turning Slope Mode Off

    All of the products on today’s list feature slope mode. This is great because it makes the measurements much more accurate. After all, a shot may be 150 yards, but if it’s 10 yards downhill, that can have a huge impact on your club selection.

    However, slope mode is not allowed by tournament play. This means that if you want to bring your rangefinder to a USGA governed event, you need to be able to deactivate slope mode.

    Some rangefinders make a point of clearly demonstrating that slope mode is off. They may do that by featuring a blinking light that goes off when the instrument is in compliance with the USGA requirements.

    This feature is nice because it can help you avoid on course disputes. So long as that light is blinking, your playing partner will never be able to accuse you of cheating.

    Pin Seeker

    It can be surprisingly difficult to know what you are measuring with a rangefinder. It may look like you’re dialed onto the flag when really you are measuring the distance to a tree behind the green. It is for precisely this reason that many rangefinders feature a pin “jolt” mode.

    This feature is great because it effectively ensures that you won’t have to second guess your readings.

    Saybien Golf Rangefinder

    Water Resistance

    You’ll also want to make sure that your rangefinder is resistant to water. Many weekend warriors won’t let a little bit of rain keep them from their weekly loop. Wouldn’t it be nice if you could safely use your range finder, even on days where the weather isn’t fully cooperating?

    Fortunately, many options are water-resistant, or even waterproof. For a little bit of extra protection, consider getting something resistant to fog. Unfortunately, excessively moist days can compromise readings, and even infiltrate the inner workings of your rangefinder. A fog-proof seal should eliminate these problems.

    Club Selection?

    We saw one unit on our list today that can actually recommend clubs. It worked by allowing players to put their average distances. It would then base its recommendations on how far you usually hit your clubs.

    This feature is great because it eliminates a lot of the guesswork that can come up during trickier shots. It also completes the caddy experience that many people are looking for from their rangefinder.

    This feature is pretty rare but still great to have when you can get it.


    You’ve read our golf rangefinder with slope reviews. Hopefully, you’ve already made your decision. If not though, it may be to your advantage to remember a couple of our personal favorites.

    If you want the best of the best, you’ll probably favor the TecTecTec VPRO500S Laser Golf Rangefinder — a high-quality product that includes just about every feature you could hope to encounter from a rangefinder.

    There is also the Saybien Golf Rangefinder — a great product that comes in at a bargain price. Ultimately, though, all 10 of these rangefinders are pretty good at what they do. You’ll just have to find the one that is most appropriate for your needs.
