The Quick Verdict
Get the Leupold GX-2c. At $149.99 versus $249.99, it's fully waterproof, ships with a published ±0.5 yard accuracy spec, and Leupold's reputation for optics is hard-earned. The Voice Caddie L6 is worth the extra $100 only if you want an OLED display and a genuinely longer range window — and you're okay with ±1 yard accuracy and water-resistance instead of waterproofing.

What They Have in Common
Both are 6x magnification rangefinders with slope modes in the same tier. Both lock onto pins and give you adjusted yardages for elevation changes. Both are light enough that you won't notice them in your bag. That's where the overlap ends — the differences underneath are more interesting than the shared headline specs suggest.
Where They Differ
Accuracy and the Spec That Actually Matters
Here's the one that jumps out: the GX-2c is rated ±0.5 yard. The L6 is rated ±1 yard. That's a doubling of the stated tolerance, and at this price tier, it's not a small thing. For a stock approach shot, one yard probably doesn't change your club. But on a 165-yard carry over water with a 6-iron that you know goes 167? You'd rather have the tighter number. Leupold's DNA engine has been around long enough that the ±0.5 claim isn't marketing fluff — that's my read, anyway, based on how consistently it shows up across their lineup.
Display: OLED vs Bold Black
The L6 runs an OLED screen, which sounds like a clear upgrade. And in low-light conditions — early morning rounds, overcast days — it probably is. OLED contrast is genuinely better in those situations. The GX-2c uses what Leupold calls a "bold black display," which is their LCD implementation. It's readable, but nobody reads a rangefinder in bright sunlight without shading it with their hand anyway. Call it a mild edge for the L6, not a decisive one.
Weather Protection
The GX-2c is waterproof. The L6 is water-resistant. Those aren't the same thing. Water-resistant holds up in a drizzle. Waterproof survives getting dropped in a puddle, rained on for three holes, or fished out of a cart cup holder that collected an inch of water overnight. If you play somewhere with real weather — Pacific Northwest, Florida in August, really anywhere that rains — waterproof matters more than it sounds on paper.
Range Window and Scan Mode
The L6 claims a 1,000-yard maximum range and includes a rapid-fire scan mode. The GX-2c tops out at 700 yards reflective, 450 yards to a pin. For most golf courses, 450 yards to a pin is enough — there aren't many par-5 flags you need to range from the tee box. But the L6's scan mode, where it updates readings continuously as you sweep across targets, is genuinely useful for finding the front edge of a green versus the flag versus the back bunker. That's a practical feature, not just a spec.
Price and What You're Buying
The $100 gap is real money. That's a decent range session, or most of a box of good balls. The GX-2c delivers Leupold's optical quality, tighter accuracy, and full waterproofing at $149.99. The L6 asks $100 more for a better screen, longer range, and a scan mode — while giving back something on accuracy and weather protection. That trade doesn't favor the L6 for most buyers.
Who Should Buy Which
Get the Leupold GX-2c if:
- You want the tightest accuracy spec in this tier — ±0.5 yard, not ±1
- You play in actual weather and want a rangefinder that's fully waterproof, not just splash-resistant
- You're buying your first quality rangefinder and want a name that'll be easy to get serviced under its 2-year warranty
- You're the golfer who plays the same course every weekend and just wants reliable yardages without fussing over screens or scan modes
Get the Voice Caddie L6 if:
- You play a lot of early-morning or overcast rounds and the OLED display genuinely matters to you — it's noticeably better in low light
- You like scanning across hazards and green complexes continuously rather than pointing and locking
- You're measuring distances beyond 700 yards for course management on long par-5s (this is rare, but some layouts call for it)
- You're someone who obsesses over display quality the way some golfers obsess over shaft feel — you'll notice it and it'll bother you if you don't have it
The Bottom Line
The L6's OLED and scan mode are genuinely nice features. But you're paying $100 more for a worse accuracy spec and a step down in weather protection. The GX-2c is tighter where it counts, built for real weather, and costs less. It's not a close call. If the L6 were priced closer to the GX-2c, the OLED alone might tip it. At a $100 premium, the math doesn't work.
