The Quick Verdict
Get the GolfBuddy GB LASER 2S PRO. For $149.99, it covers every core feature you actually need from a rangefinder — slope, pin-finding vibration, scan mode, magnetic mount — and the CR2 battery means you're never stranded on hole 14 because you forgot to charge something. The Voice Caddie L6 is worth the extra $100 only if you specifically want an OLED display and water resistance, and you've decided those two things matter more than a hundred bucks.

What They Have in Common
Both are Tier 4 rangefinders with 6x magnification, ±1 yard accuracy, slope mode, pin-finding vibration, and scan mode. They're genuinely comparable in range — 1,093 yards vs 1,000 yards, which in practice is the same thing unless you're trying to range a barn door across a valley. At their cores, these are honest mid-tier rangefinders doing the same job.
Where They Differ
Price and What You're Getting for the Gap
A hundred dollars is real money in this tier. The GolfBuddy comes in at $149.99; the Voice Caddie L6 is $249.99. That gap needs to be justified by the hardware, and honestly, it's a thinner case than you'd expect at first glance. The L6 gets you an OLED display and water resistance. That's the list. The GolfBuddy brings a magnetic mount, belt clip, and a battery format (CR2) that you can grab at any pharmacy on the planet. Whether the L6's premium is worth it depends entirely on how much those two features mean to you.
Display: OLED vs. Unknown
Here's where the Voice Caddie makes its clearest argument. OLED displays are genuinely better for rangefinder use — sharper contrast, better readability in variable light, cleaner look through the eyepiece. GolfBuddy doesn't publish what display type the 2S Pro uses. In real-world use, the difference is most noticeable when you're reading yardages in shade versus bright glare — neither display is perfect, but OLED typically edges out LCD in those in-between conditions.
Water Resistance
The Voice Caddie L6 is rated water-resistant. The GolfBuddy 2S Pro has no published water resistance rating at all. If you're regularly teeing off in the Pacific Northwest or playing fall rounds in soggy conditions, that matters. A rangefinder that gets wet and dies is worth nothing. That said, most golfers in most conditions are fine — and if it's truly pouring, you probably shouldn't be out there anyway.
Battery and Mounting
The GolfBuddy runs on a CR2 lithium battery rated for 5,000+ actuations. CR2 batteries are at every pharmacy in the country, which matters when you're mid-round and realize you're running low. The Voice Caddie L6 doesn't publish battery specs at all, which makes it hard to compare directly. The GolfBuddy also includes a magnetic mount and belt clip out of the box — useful, practical, and not something you want to buy separately. Voice Caddie doesn't mention a mount for the L6.
GolfBuddy's Extras
The 2S Pro includes a "Buddy Mode" and triangulation feature, along with what GolfBuddy calls ZST Plus — a speed technology for fast measurements (0.15 seconds). These aren't dealbreakers either way, but the triangulation feature is genuinely useful for verifying a flag distance when you're not sure you've locked the right target. The L6 doesn't list an equivalent.
Who Should Buy Which
Get the GolfBuddy GB LASER 2S PRO if:
- You want a capable slope rangefinder without spending $250
- You play year-round and want the peace of mind of CR2 batteries you can find anywhere, any time
- You're the golfer who forgets to charge things — a rangefinder that runs on a replaceable battery is one less thing to think about
- You want a magnetic mount included without paying for an accessory separately
Get the Voice Caddie L6 if:
- You tee off at 6:30am on October mornings when the light is flat and murky and you want the sharpest display possible — that's where OLED earns its keep
- You play in wet climates and have killed a non-waterproof rangefinder before
- You've handled both and the OLED display through the eyepiece was noticeably better to your eye
- Display quality is genuinely the feature you optimize for
The Bottom Line
The GolfBuddy GB LASER 2S PRO does the job — slope, vibration, scan mode, magnetic mount, replaceable battery — for $149.99. The Voice Caddie L6 has a better display and water resistance, and those things are real. But at $100 more, the L6 is asking you to pay a premium for two features that most golfers in most conditions won't notice every round. If the OLED and water resistance are specifically what you're after, the L6 is worth it. For everyone else, the GolfBuddy gets you there.
