The Quick Verdict

Get the GolfBuddy GB LASER 2S PRO. At $149.99 versus $220 for the Nikon, the $70 gap is real money — and the GolfBuddy gives up almost nothing to earn those savings. Its range is 300 yards longer, it has a faster measuring speed, and it includes slope with a magnetic mount. The COOLSHOT 20i GIII is worth a look only if you specifically want rainproofing and a five-year warranty, and those matter enough to you to pay a meaningful premium for them.


What They Have in Common

Both are 6x magnification rangefinders with slope, ±1 yard accuracy to 100 meters, and CR2 battery operation. They're in the same price tier and aimed at the same buyer: someone who wants a reliable, slope-equipped rangefinder without spending $350 on a Bushnell Pro X3. Neither connects to an app or has GPS. These are pure laser rangefinders.


Where They Differ

Range and Speed

The GolfBuddy reaches out to 1,093 yards; the Nikon tops out at 800. For actual golf, neither limit matters much — flags are rarely beyond 500 yards, and even forced carries to layoff spots seldom push past 300. So this isn't a practical edge for most rounds. Where the GolfBuddy does have a meaningful edge is measuring speed: it claims 0.15 seconds, which is genuinely fast. The Nikon's spec sheet doesn't publish a measurement speed, though it does list an 8-second scan mode. I'd guess the real-world difference is small, but fast acquisition is one of those things you notice when conditions are tough — shaky hands, low light, gusty days.

Accuracy — Closer Look

Both claim ±1 yard, but there's a catch with the Nikon: that rating applies to 100 meters (about 109 yards). Beyond that, Nikon specifies ±2 yards. The GolfBuddy lists ±1 yard without a stated distance cap. Whether ±2 yards matters on a 220-yard par 3 is debatable — you're probably not going to flush a 5-iron to exactly that number anyway — but it's worth knowing the specs aren't identical.

Slope Features

Both units have slope mode. The GolfBuddy calls its implementation "ZST Plus" with what it describes as triangulation — essentially a more involved calculation of the angle and adjusted yardage. The Nikon calls theirs "ID Slope" and includes a physical slope switch, which makes toggling tournament-legal mode a simple flip rather than a menu navigation. Honest admission: you'll toggle slope off before you tee off in a tournament. You'll probably forget and play the whole round in non-slope mode anyway. Still, the Nikon's physical switch is a nicer implementation if that routine matters to you.

Build, Weather, and the Warranty Question

Here's where the Nikon earns its higher price. It's rated rainproof; the GolfBuddy has no published water resistance rating. If you play early mornings or live somewhere that gets afternoon showers, that matters. The GolfBuddy also comes in at 161g versus Nikon's 130g — not a dramatic difference, but the Nikon's lighter and slightly more compact footprint does make it easier to pocket.

The Nikon also carries a five-year warranty. GolfBuddy doesn't publish one in the spec data I have. Five years is a long window for electronics in a category where models turn over pretty regularly, but it's a real differentiator if you keep your gear for a while.

The GolfBuddy brings a magnetic mount and belt clip as standard. The Nikon includes neither in its listed features. If you use a cart rail or magnetic mount system, you'd need to add one separately for the Nikon.


Who Should Buy Which

Get the GolfBuddy GB LASER 2S PRO if:

  • You want a solid slope rangefinder at an honest price and the $70 you'd spend on the Nikon upgrade is a sleeve and a half of Pro V1s you'd rather keep.
  • You use a magnetic cart mount — it's included, not an add-on.
  • You're buying your first rangefinder and want to see how much you actually use the thing before committing more.
  • You're the golfer who plays three or four times a month on dry afternoons in good weather and has no real use for rainproofing.

Get the Nikon COOLSHOT 20i GIII if:

  • You tee off at 7am on October mornings when the fairways are still wet and you want to know the rangefinder will survive the round.
  • You keep gear for five-plus years and want the warranty peace of mind — the Nikon's five-year coverage is genuinely uncommon at this price.
  • The physical slope toggle matters to you: you play in tournaments, you switch modes often, and a flip switch is faster than a button sequence.
  • You're buying this as a gift and want something that feels premium in-hand. The Nikon's lighter build and Nikon optics branding carry some perceived quality that's hard to quantify but real.

The Bottom Line

The GolfBuddy LASER 2S PRO does the main job — fast, accurate, slope-adjusted yardages — for $70 less. The Nikon's advantages are real but specific: rainproofing, a longer warranty, and a slightly more polished feel. If those things speak to your situation, pay the premium. If they don't, you're spending $70 for features you won't use. Most golfers playing recreational rounds in normal conditions won't feel the difference.

Can I use these rangefinders in tournament play?
Both the GolfBuddy GB LASER 2S PRO and Nikon COOLSHOT 20i GIII have a tournament-legal slope switch — toggle slope off and the unit becomes USGA-conforming for events that prohibit slope compensation. Check your specific competition rules, but a slope-switch unit is accepted in most handicap and club formats when the switch is off.
